Earbuds so nice, I purchased twice
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.

Excellent Customer Service!!! This is for bass lovers and folks with multiple devices...
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.

Excellent Product for the Price
I purchased these to use these for running paired with an Apple watch. I think they are really nice considering the price point. Pros: Nice fit. My first pair of "open" earbuds which takes a little getting used to, but on balance I like being able to hear the outside world while I'm running. Good sound quality. Open style didn't degrade the sound as much as I thought it might. In the context of price point, overall above average. Pairing very simple and has worked uninterrupted so far. Seem to last as advertised from a charging perspective. Con: Volume control is difficult IMO. I find this a common thread among running earbuds I have used. Overall a good investment and I would recommend at this price point.

Best buds for the price!
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.

very good quality at an excellent price.
I was at first looking for a pair of small over the ear traditional headphones for my wife. She cannot find ear buds that are comfortable ( very small ear canal), and her full size Sony headphones are just too cumbersome in some situations. In my research I found the TOZO O2 open-ear headphones. They reminded me of the over- the- ear hooked headset we used for our cell phones many years ago. The TOZO O2 appeared to be the perfect fit for her problem, something that could go over her ear without messing up her hair or making it uncomfortable to wear a hat outdoors. After about two weeks of using them she is absolutely in love with them. She uses them around the house, when she is out walking, or working in the garden. They are lightweight and she says that she doesn't even realize she is wearing them sometimes. I am especially happy that when she wears them while walking around the neighborhood she can still hear cars , kids on bikes , or just the neighbors saying hello. I have used them a few times and for my needs they are worth twice the price. The sound is crisp and clear with good bass that's not overwhelming and great mid tones for listening to music or podcasts. The TOZO app allows her and I to adjust the sound to our own tastes, which is a great feature. The batteries have lasted over 30 listening hours in the charging case. The charging case is small enough for me to drop it into my pants pocket or for my wife to drop into her sling bag. The TOZO O2 was an excellent choice for us and I would strongly recommend them to anyone who is on the go and enjoys great sound, and especially so for those who can not comfortably wear earbuds.

Not impressed at all.
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.

Amazing Headphone!
Absolutely love! Great sound. Easy to connect. Perfect size. Worth the money. Very durable. They are water resistant too which makes it even better. I absolutely love them. 100% better then my old ones. Im so glad I switched to these. Definitely worth the purchase and money. They block out the sound around me too which is amazing. I love them so much! My house is very loud with normally 3 kids and 1 dog but sunday dinners we have a housefull. 6 - 8 kids 5 - 7 adults, 2 dogs these block everything/everyone out. I definitely needed them.

Open ear, great sound, long battery life, great price...what more could you want?
We've become real TOZO fans here, have several models now. Great quality, great prices, hard to beat. And I'm a music fan--almost all types--and listen about 20/7 (yes, most of the night on low profile TOZO T6), and I don't tolerate poor music quality I noticed everytime I wore closed earbuds or my terrific TOZO headset, I was yelling at people because I couldn't hear my own voice. So when I lost one of my beloved red T21s, I decided to go with over-the-ear (not as easy to lose) and open ear. LOVE these! Terrific sound for music (with equalizer settings) and I can hear anything I want to around me; no more yelling because I can't hear my own voice. Mic is great for calls with same friendly TOZO commands. Long-lasting charge (days), which is good, as I do miss the case numbers telling me how much charge is left. But I was already using the TOZO app for the other TOZO items, and remaining charge for these is easily seen on that. Another great product from TOZO--Thank you!!!

What a fabulous pair of earphones, I'm in love haha!!
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!!!!!

Sorprenden muchísimo por el precio que tienen
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.

Ses seviyesi gayet yeterli
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

oordopjes om muziek te beluisteren.
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.

Super competitive wireless earbuds on a budget
** 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.
