O2 Open Ear Wireless Earbuds,Multi-Angle Adjust 42H Bluetooth 5.3

These are comfortable and have great quality sound, even compared to my AirPod Pros. I stopped using my AirPods because they were starting to have some problems and also weren’t very comfortable for long time wear, but the Tozo Openbuds have performed just as well if not better in every area. They connect easily to my phone (and my computer if I want), they don’t cause any ear wax buildup since they are open, they are comfortable, they have a good mic for phone calls, a long battery life, and are overall just easy to use. In case it’s a concern to anyone, as a full-time glasses wearer, these don’t interfere with my glasses at all. They are lightweight enough that it’s easy to forget I have them on. They’re adjustable so once you find the right spot for them they are snug and cozy. The only thing I miss about my AirPods that these don’t do is noise cancellation, but even when I’ve been seated next to the jet on a plane, if I position the right over my ear hole they do pretty well anyway. I’m constantly recommending these to people in my personal life since I like them so much and they’re not a bad price for the quality. Big fan.

Update 3/5/2025: After almost 3 years (purchased 6/29/2022) using these earbuds, they are still great. They seem to do well enough on calls, so it may have been location that was the issue in the past. The only negative (still) is that they fall out very easily. If the stem that goes into the ear canal was longer and the oval piece at the outside was not so large, I think they would be more secure. If that was fixed, they would be perfect. I love these for traveling, to have the case hanging around my neck for easy access and for keeping charged. Even with them easily falling out, I would still recommend them and would buy again if the need arose for another pair of earbuds. Update 8/22/2022: I've had a couple phone calls using these earbuds, and both calls the other person said I was hard to hear or was breaking up. When I switched to my wired earbuds then the other person could hear me fine. So, in my experience, these wireless earbuds are great for listening, but not great for calls where you need to be heard clearly. I would still buy them again, but for listening use only. Original review July 2022: These TOZO T10 earbuds have turned out to be great. At first I wasn't so sure, but after a month of using them, traveling and at home, I really like them. I'm still not completely comfortable with how easily they could fall out and get lost, but other than that, they're fabulous. The sound is ideal, in my opinion. Just the perfect balance of bass, treble and mid range. The noise cancelling is really good. I don't usually wear both at the same time, because I want to be able to hear my surroundings (for safety), but when I have worn both on the airplane and at home, they do a really good job of blocking out external noises. The charging case is awesome. I typically wear one earbud at a time and then switch to the other one when the battery gets low in the first. I'd say it's probably 6 hours before I get the low battery warning. The individual buds switch on/off and connect without any effort other than taking them out of the case. The charging case can recharge the earbuds a few times, before the case itself needs charging. I like that the case charging port is a USB C. My other personal devices all use the same cable, so I don't have to carry a different one for this. The earbud case does come with its own charging cable included, if needed. It is a power only cable (not for data transfer). The instructions say the case is wireless charging as well. I don't do any of that wireless charging stuff myself, but for those of you that do, it says the case can be charged that way too. The "lanyard" that came with it I found to be useless, as it was just a narrow strap with a tension buckle that wouldn't hold tight. So instead, I just used a lanyard I already had - easy fix. I like that I can wear the case around my neck, which was very convenient while traveling, so I didn't have to search through a bag to find it, and had them easily accessible. Recently, I started using them with my TV at home, which was such a great discovery! I didn't even think about using them for that, until I read another reviewer mention it. I was so excited when I found that they worked really well with my Fire TV. Interesting thing is that when the earbuds are connected the volume level changes to 50+, but the normal volume when they're not connected I have set at 13. When I first saw the 50+ volume level my concern was that it would stay at that level when they disconnected. But I was happy that when they disconnected the volume reverted to the normal level. Whew! When the earbuds are connected to the TV, I can change the volume up/down with the remote like normal, as well as with the earbuds (hold left for down, hold right for up). Another reviewer said they couldn't adjust the volume, but I don't have any trouble doing so. Noted exception: changing the volume down using the left earbud only works when both earbuds are connected. If only one is connected then the earbud will only increase the volume, not decrease it. The earbuds are comfortable for wearing a long time. I have small ears/auricles so most earbuds are too big around and make my ears sore after just a short time. These TOZO earbuds are a good size and don't make my ears hurt, even after wearing 8 hours. I use the smallest ear cap (it comes with 4 sizes). I also like that the earbuds are almost identical in shape, so they're basically interchangeable, even though there is a left and a right earbud. Since I usually just wear one at a time, and I like to wear in my left ear, I can switch earbuds when the battery gets low and wear the right one in my left ear. The only minor improvement, in my opinion, would be if the headset part was a bit narrower and the stem that goes into the ear canal was just a touch longer, which would give a more secure seating to not fall out as easily and have a more direct sound angle. But that's just a personal preference, not anything negative about the product. Overall, I would highly recommend these earbuds and would buy again.

Firstly, these headphones for the price are amazing. Pros: - Fully adjustable to your ears - Pretty good sound quality - Volume can be waaaayyyy loud - Cheap - Great microphone quality - Don't hurt my ears after wearing them for some time - THEY DON"T FALL OFF!!!!!!! The reason I gave 4 stars instead of 5... - When you put them in the charging case, all your adjustments go away and you have to refit them to your ears everytime because of how they lay in the case. Not a major deal because of how easy it is to adjust them, however it was a little annoying. - While the headphones can play very loudly, everyone can hear whatever you are listening to as well. Because they don't sit inside your ear like a standard earbud, they also allow for others to hear your music much more clearly. - The noise cancellation is not the best. This is pretty much due to the fact they sit on the outside of your ear canal and not inside or cover your whole ear. I used them while weedwacking and could hear everything around me. As far as microphone noise cancelation, I used them in a call in a noisy house and received zero complaints. Overall, I have never used headphones like these before, I always used to get the in ear or over the head ones but over time they start to hurt my ears/head. I enjoy these headphones. A minor side note, this brand I have bought a few different products from and really enjoy them. The one time I had a issue their support team was more than helpful and efficient with their responses. Highly recommend.

Since posting my original middling review on Amazon, the company’s customer service proactively reached out to me with concerns that the earbuds I received may have been a defective item. I must say that floored me because I had previously stated in my review that I had no intention of returning the earbuds... and I am still within window to return them as I write this updated review. Tozo’s customer service offered to either give me a gift card for the purchase price I paid or to give me an upgraded set of Tozo earbuds. Not really interested in the cash, I took them up on the offer of the upgraded earbuds. I received the Tozo T6 earbuds and could not be happier. A quick note on the differences for folks who may be comparing these two: Tozo T10 - I think the bass is better on this pair and after I purchased a fast charging USB-C cord, I am able to get the charging base to fully charge. The key benefits of this one over the T6 is that you can pair each earbud as if it was a separate blue tooth device AND you can pair each/both to two devices at a time. So I would say the Tozo T10’s are for the guy/gal with multiple devices they use daily and bass lovers. Tozo T6 - In hindsight, this is the pair I should have purchased. The charging case is essentially the same size as an Airpods case, it’s IPX8 waterproof has very good bass. The case is noticeably smaller (in a good way) in your pocket. These earbuds have the same quality that I often describe Apple products with: “it just works.” You won’t pair these earbuds separately and with multiple devices at a time... and I don’t care. I love them. So all in, I love Tozo’s products and especially their customer service. Read up on the differences between the Tozo T10 and T6 and make the best decision for yourself... and know that their customer service folks are responsive and want you to be happy! That’s rare and I’m eternally grateful. =============================== ORIGINAL REVIEW: It hard for me to rate this product because I want to love it. Here are my pros, cons, things to consider and final thoughts: PROS: -The bass is legitimately excellent. The speaker drivers are better than any wireless earbuds I have ever used. I am not an audophile nor do I buy $150+ headphones but the sound is legit for hip hop, dance, and other similar music. -the sound is also very good. Not excellent, like the base, but it is very good. No complains here. -Other miscellaneous features that I liked were true to description: water protection, battery life, overall build quality. -Price is extremely affordable compared to other higher end alternatives. I'd rather buy three of these than one pair of Beats headphones. -the earbuds batteries never have run out on me. I run/walk for about two hours each day, so I admittedly have never tried to really drain them. When you read the problems below, this will seem more like a pro point. -these earbuds can pair to two devices at the same time. So I usually have my iPad and iPhone paired up without having to switch between them in the settings. CONS: -bluetooth connection - if you follow the instructions, the separate earbuds pair automatically with each other with no problems. the problem is that I feel like there is a 1-10 minute period where the headphones are "searching" for my phone no matter how close it is to me for a successfully, no drop pairing. The sound can cut out or dip for a minimal period while it is going through this phase, but it's annoying. -Using two earbuds at the same time - My usual usage case is walking/standing with my earbuds in and my phone in my pocket. If i tilt my head in one direction or another one or both headphones lose the connection momentarily BUT they do automatically pair back up. It usually goes away the longer I have them in my ears but I am afraid to leave my phone on a table and walk any reasonable distance away. i am not confident they will stay paired if I was on the opposite end of the same room with no obstructions. -Turning off the earbuds. I think this annoys me the most... I may be wrong in this desire, but I wish the earbuds would automatically shut off when I put them in the charging case. They DON'T! I have put them in the charging base for hours and then realized that they were on the whole time. Which means that they do have a charge, but they were draining the base unnecessarily while I thought I had it plugged in and was charging the base and the earbuds. I've bought a fast charging USB C to micro USB charging cord in hopes that it'll help. The current safest thing I can do to get them to turn off faster/automatically is to have both my iPad and iPhone "forget the device" so that it times out versus remains on and draining the batteries. -the base takes forever to fully charge. related to the above point, I have NEVER had a fully charged base unit. Things to consider: If you're still reading this, these are true wireless headphones. I am currently within the return window, but I won't be returning these earbuds. This is mostly because my expectations are low given the price point. My core headphones are a pair of Apple Airpods Pros. So this pair suffers from me comparing them to a $200+ pair that "simply works." Some additional thoughts and tips that are neither pros/cons to me: -You can use each earbud as a separate "device." When you turn on bluetooth you see each earbud listed as a separate bluetooth device. So, follow their recommendation when it says ONLY use the right earbud as your connection via our phone/device. The right will automatically "add in" the left earbud, but the reverse is not true. What this means is that you can pair one earbud to one device and one to another. This sucks when you then want to pair them together again.. so I use the "forget this device" setting after every independent use of the left earbud. In summary, I want to love these earbuds, but the annoying fickle ways that the bluetooth works or momentarily drops whenever I first put them in my ears was something I could have accepted because of my use case. Add in the fact that its an annoying process to get the earbuds to turn off 100% of the time which effectively makes it near impossible to fully charge the base and you understand why I am writing this review. Again, I am not returning them! I love the sound. I almost always use them in exercise use cases or when I know I am going to be acting carelessly or around water/rain or in a situation where I am concerned about potential theft of my Airpod Pros. So as a second bluetooth device, these are excellent. As your primary headphones, I give them a three out of five stars.

While I have never tried a pricier pair of wireless earbuds like those created by Google, Sony, B&O, etc., this pair of ear buds definitely are worth their money. ========== Sound quality The volume gets loud enough, and sound is fine. I'm not super audiophile, but I do own about 4 pairs of earphones and headphones/earphones, and this pair doesn't lack in audio quality compared to them. The bass isn't too punchy, which is actually something I like. Ever since Beats by Dre came out, every ear bud manufacturer has been just pumping the bass too much. This isn't one of them. I rated the noise cancellation 3 stars because I didn't buy these to get lost in my own world. I have my Sony headphones for that. ========== Phone quality I was afraid the mics were too removed from my mouth to actually pick up any meaningful sound, but they seem to be fine. Nobody I've been on call with said they can't hear me or something when I'm indoor. However, when I'm outdoors and it's a bit windy, I had to speak up a bit for the recipient to understand what I'm saying. But overall, I'm satisfied. ========== Comfort It's comfortable. When I'm not listening to anything, I can have conversation with people no problem. Actually, even with a bit of music on, I can talk to people. ========== Battery life Battery life is phenomenal. It has these indicators in the case that tells you how much battery the case has, so you don't ever have to worry about running out of battery. The case can be charged wirelessly, and via USB-C cable, so I never worried about battery life. ========== Work out I go on 3.6 mile runs 4 times a week outside. So far, it has stayed in my ear pretty well. Of course it slips a little if you don't fit it in tightly, but in general when I go for a run, I have to maybe adjust the earbuds once or twice at the most during the run, and it stays in the ear fine. It comes with 3 different sizes of ear tips, so you can use whatever fits you best. When I'm just doing calisthenics, it stays in my ear fine. ========== Usability Setting up was super easy on my Google Pixel 3. The earbuds come with some battery charged, so I could pair it up immediately out of the box. Once paired, you can use one ear bud at a time, while leaving the other in the case. I suppose this means when on a long road trip, you can switch between the two to conserve battery. When you take out one out of the case and another one later, there's no syncing issue. I left my phone in one end of my home in a different floor and went to the other end of the lower floor, and it stayed connected to the phone. Even when I was out of range, when I got back in the range, it worked fine. I haven't really had the chance to use it in a rainy condition, so I can't attest to that. I love how it has different functionalities built into different taps to the middle of the earbud. You can go to prev/next track, and raise or lower volume by tapping the ear buds. Tapping your earbud in the middle takes a bit of a practice, though, especially while running. You'd think you know exactly where your ear hole is, but it's actually fairly hard to find it in one tap. But that's just practice. ========== Aesthetics I think the design is pretty good on their own, and when I wear them, but then I'm a fairly big guy, with a big head so it's okay. They look a bit ridiculous on people with smaller head, IMO. ========== Down side - When going to next or previous track by tapping the earbuds, I wish it was simply some beeps instead of a female voice saying "forward," and whatever the other word was. - Speaking of voice, this earbud pair comes with several voice prompts: "forward," "previous (I think)," "power on," "your headset is connected," etc. The problem is, ALL of them are different female voices with different English accents. Some of them are a bit slower than the other, and they're either British, American, or what I think is Austrailian English. ========== Overall I don't know what the more expensive name brands have to offer, but this pair is just fine for me, especially for $30 or so (I bought it during promotion, so it was in the $20s). I was afraid of getting some defective product, but two month in, it's doing just fine. I'll be sure to update when it goes bonkers in another month or so. But so far, so good.

Not to happy with these. Right off the bat, you dont know what the weird sounds their making mean. They shut off for no reason. You have to constantly pair them. The volume changes for no reason. You do nt know what state of charge their in. The case doesn't indicate anything, charge state of earbuds or docking case. I really wanted to like these but I'm not satisfied. I do like the fit, the sound, the adjustment of the earbud, and the ability to pair with multiple devices, which is why I love the Tozo brand, but they missed the mark on these. So the hunt continues. I might just need to shell out a few hundred. After all I've spent more looking for the ones.

TOZO has recently gotten into a big trend of releasing these open ear style headphones and while none of them will replace normal in ear earbuds or full over ear headphones in BASS offering, the audio they do deliver really is fantastic given the design limitations while offering the open ear freedom and comfort. The TOZO OpenEarRing buds have been my favorite for a while now. Offering a very unique sort of clip on method and comfort while being really good sounding while I do various household activities. In comes the new O2's and I have to say, these may be my new favorite choice, if anything, a set I plan to use a lot alongside the OpenEarRing's. Audio quality is very good to my untrained ear, the fit over the ear with this new hook style actually feels really comfortable and stable when moving around, and has the added benefit of having a range of adjustment with a clickety hinge that has a pretty good range in it as seen in the pictures. Once you put these things on, they stay in place pretty good and the hinge allows you to adjust the way they position in your ear to optimize the sound going into your ear hole which isn't something you get quite as well from un-adjustable offerings that you have to sort of move into place, and hope they stay. These ones hook on your ear until you are happy and they sit nicely, then you can then adjust the bud itself optimally which then both seem to stay in place really well. It's a unique but very effective design which I really like personally. Like usual, the buds are Bluetooth and seem to have reasonably good range and signal with the latest BT 5.3. It is possible to get them to have a little trouble if you move in a way that blocks your phone from the line of site to the buds and mess with the signal, but it's a lot less of a problem than it was on some of the older bud designs. Battey life seems about on par for the size and design, with charging speed of the buds being reasonably quick to get a few hours of charge with only a few minutes of time spent in the charging case. The case itself is a neat design that's flatter and wider than previous bud designs that go for that taller shape which is just different but still easily pocketable and portable. Possibly it would have been nice if the case was wirelessly chargeable like some older offerings like the T10's since the case size lends to being perfect for that, but it's USB-C and charges perfectly fine by itself and holds a bunch of charge to charge the Buds with while out and about. The buds are also like all of TOZO's more recent offerings, able to connect to the TOZO app on your phone, be adjusted within the app even to change the control methods for both sides to whatever you want, and push FW Updates to the buds to improve them as TOZO releases updates and fixes. (Which has helped a lot of their older designs that have ANC which improved a lot from an earlier to later FW version). Overall like most TOZO offerings, their headphone/earbud offerings continue to be extremely good value for money. I like to keep up on each model they release as I use headphone nearly constantly in my life for both Music, Entertainment, and Work and they area fantastic offering for all of that with options galore you can afford to buy multiple of for the price of one "Premium" model from other Brands. Maybe some of those brands can justify that price in some way shape or form, but for the most part, TOZO really gets within an arms throw for such a better price that it makes the jump hard to justify in my own experience. TLDR : If you are in the market for a set of fantastic open ear buds and want a pair that can fit pretty much any ear and sound great doing it, give these a try. Solidly Recommend.

Thought I would do a one year review since I believe I didn't give an initial review of the TOZO O2. Two words. love'Em! Very comfortable. I forget they're hanging on my ears more than once and have only remembered when I lay down. I've read other reviews about them making strange noises and they do but if you know what they are of no concern. One is a dbl beep that lets you know that your out of range from your source which is in my guesstimate is about 50 ft. The other is a low battery warning. A graduating lower tone. A mentioned previously I've only had problems with connection about about 50 ft from my phone. Then I just pop it back in my case and back in my ear. Problem solved. I'm really happy with the quality of sound and durability so far with Tozo. I even purchased a pair of TOZO HT3s. My roommate was even impressed and purchased a set of O2.

These are my first pair of wireless in-ear earphones, I'd put off getting a new pair because I'm no longer that computer savvy and I usually give all those things to my son to sort out for me (he's 32 and knows what he's doing!). So the most obvious thing I like is the fact I'm no longer tethered to a computer, iMac or phone by wires, excellent thinking whoever came up with original idea!!!! On taking the earphones out of the box, they paired instantly completely on their own, I didn't have to do a thing! Bluetooth took care of pairing to my various devices, fabulous. However, the most obvious and fantastic thing is the sound quality of these little beauties, so crisp and clear, good treble, good bass. Overall simply fantastic sound clarity - I mean, I have several headphones: Sennheiser, Bose, Sony, Ludos and some other lesser known brands, and these earphone far exceed the quality, design, comfort, and build of all of them, in my humble opinion. I've tried a number of different styles of music on them: classical, classical guitar & world music (Jesse Cook, Acoustic Alchemy and Peter White), Opera, vocal, smooth jazz, easy-listening, rock and indie; my favourite Creedence Clearwater Revival (CCR), just blew me away as does Nelson Rangell (sax and flute) and Dave Koz sax). It's right for me to say that I am well and truly in love with the Tozo T10. I did make a small adjustment to the earbuds though and swapped them out for a pair of small memory foam ones, but these earphones come with several sized silicone buds., so a fit for everyone. I do find that noise cancelling works most effectively with memory foam buds and they are really inexpensive to buy and they make a huge difference........I can't even hear my doorbell or the cats meowing when I use these earphones! I can go mad without creating noise pollution for my neighbours.....yay lol. The only other thing I would say, is that having recently undergone major abdominal surgery to remove a couple of cancer ridden organs, quickly followed by contracting acute pancreatitis (both ongoing situations), these earphones have added so much pleasure into my life. What a way to lie back in bed, relax and let the music and sound float me away, it makes my pain so much easier to deal with. Thank you so much Tozo for providing such exceptionally good earphones, I bet you never thought of that little bonus when you produced the T10. How can you possibly improve or make the sound and comfort any better?? By the way, I bought these online, based on reviews provided by other buyers on Amazon, at around 10pm in the evening and they arrived at 2.45pm the following day, secure in good packaging!!!!!

Llevaba tiempo buscando unos auriculares Bluetooth económicos para el día a día y estos TOZO T10 me han sorprendido para bien. El emparejamiento con el móvil fue inmediato y, desde entonces, se conectan solos cada vez que los saco del estuche. El sonido tiene unos graves potentes, pero sin perder claridad en las voces, y la batería aguanta bastante más de lo que esperaba. Además, son muy cómodos incluso después de llevarlos un buen rato puestos, y el estuche ocupa muy poco. Los uso para escuchar música, ver vídeos e incluso hacer llamadas, y cumplen de sobra. Por el precio que tienen, me parecen una compra excelente.

Tam kablosuz bir kulaklık için çok güzel. Yazılan yorumlar çok isabetli. •Kutusu cepte taşımak için büyük •Ses kalitesi ve yüksekliği gayet yeterli •Sıvı geçirmiyor •kutusundaki şarj ile 2 tam günü rahatlıkla çıkarıyor •Sağ kulaklık üzerindeki mikrofon çok iyi çalıştığı için telefonla konuşurken sorun yaşarsanız sol tek kulakta, sağ tek mikrofon gibi ağıza yaklaştırıp kullanılabiliyor. •Kutusundan çıkarınca 2 saniye içinde (kulağa takana kadar) telefona bağlanmış oluyor

Het opladen in het doosje is leuk en gemakkelijk. De oortjes blijven bij mij niet goed zitten en wanneer ik ze dan goed wou steken drukte ik regelmatig , per ongeluk , op stop. Het geluid is goed.

** UPDATE: more than 3 years later, these little ear buds are still going STRONG. I can not use them for weeks if not months and they are still charged. Still great sound, still connecting easily, still absolutely no complaints. Highly recommend! Super easy to connect, and love the ear bud shape. Sound was great, and they even charge wirelessly. My spouse bought a different brand for over 100.00 and these do all the same things.
