EarFunAir Pro 4 Adaptive Hybrid Noise Canceling Wireless Earbuds, Qualcomm Snapdragon Sound, aptX™ Lossless, 6 Mics AI CVC 8.0 Call, LDAC Hi-Res Audio, 52H Playtime, Bluetooth 5.4, in-Ear Detection

Fantastic for the price. These aren't quite as good for flying as an over-the-ear Bose or the like, but they're pretty darn good and small too. Battery lasts for ages. Very comfortable; I can listen for hours. They are my go-to for traveling light and listening in a noisy environment. I used them sitting at a busy pool with other music going, pool motor sounds, kids yelling, and I was totally lost in my music. The ANC does a fantastic job of blocking out outside sound. Sound quality is great. My music sounds amazing. Punchy bass, great tone for rock. I love these headphones. I tried some foam olives to see if isolation could be even better, but it didn't make much of a difference and didn't seat nicely in the case, so I'm sticking with the silicone olives it came with that work quite well. A steal at this price point.

These headphones have it all, and everything is done well. They have a great fit; the silicone tips are soft and comfortable, even during long hours of wear, the earbud shape also helped. The features are impressive: everything can be customized in the app, ear detection works amazingly well, and I appreciate the sunk touch sensor that prevents accidental touches on the controls.The sound quality is fantastic, and if you ask me, they sound better than other overpriced fruity earbuds on the market. The noise cancellation was excellent during my flight, blocking out the sound of the plane engines like a champion. Speaking of my flight, which lasted almost nine hours, I kept the volume at around 60% with noise cancelling on, and I didn't have to charge them once—I still had battery left when landing! That's amazing; I didn't even think about it until now.They can be paired with two devices simultaneously, and they don't switch automatically to the device I'm not using for every email notification, which is great.They are also beautiful. I got the black ones, which have a slight bluish tint in the stem, and I love them, though now I think I would have loved them even more in white.Great job, Earfun! Thanks!

Let me preface this by saying that I am not an audio expert, but rather a regular user. I had been a user of Earfun Air Pro 3 for about a year and I REALLY liked it. So, I was excited when the Earfun Air Pro 4 came out and I bought it since I got a 30% off (early adopter benefits ig). And it actually is what it advertises itself as! It features Sony's LDAC codec, along with Qualcomm's aptX Adaptive codecs, AND Bluetooth LE support with the LC3 codec, which is literally unheard of for the pricepoint that it sells at. On top of that, it has Google Fast Pair support and has the runs atop the latest Bluetooth 5.4 standard. I have a Google Pixel 8 Pro so I have all of the aforementioned feature and codec support.First impressions are completely positive. Even without using any equalizers, it sounds crisp and wonderful. The bass is just where it should be and isn't overpowering. Same with the treble. It has 6 noise cancellation levels. The noise cancellation is excellent for its price point. I felt that the AI based noise cancellation settings need some work, so I primarily stick with the Strong and Balanced settings. It also has numerous built-in EQ profiles and a custom equalizer for anyone who needs it. I haven't had the opportunity to test the battery life, but I belive it would be better than the previous Earfun Air Pro 3 since that lasted very long for my use case. I NEVER had it run out on me, so I expect the same with this. The in-ear detection feature also works great. Now, onto some criticism ...What I didn't like is that Earfun never mentioned that you cannot have the options of all codecs at once. They're all an either or. AptX is the most "compatible" codec with it not affecting the availability of other features of the product. LE and LDAC have to be enabled manually, and are mutually exclusive. On top of that, enabling LE **disables** the aptX and LDAC codecs, Fast Pair support, and Game Mode support. I then later researched this and found out that the codec disabling is because of the experimental nature of the LC3 (Bluetooth LE) codec. It doesn't mention it, but enabling LDAC **disables** the aptX and LC3 (Bluetooth LE) codecs since I couldn't find the option to switch to the other two in the codecs in the Developer Options menu.Also, when you do enable the LE codec, you then have to manually go into the Bluetooth settings for the Pixel and then enable LE Audio, but that's probably a Google issue. However, when you do have that option selected and go into the Developer Settings option, it doesn't show LC3 codec as selected but rather says "Use System Selection (Default)." I am not sure what's going on, but I will give the benefit of the doubt here that LE is indeed active, and it is some bug on Android's side. What I also don't like is that the in-ear detection is VERY sensitive. It just takes a little bit of the earbud to loosen in the ear for it to activate, which is really frustrating especially in outdoor settings and in physical activity based settings. I hope they can somehow lower the sensitivity.Overall, it's an extreme value product and is a steal for its price point, and more so when you have discount coupons. Consider the points I listed above when purchasing the product. I have attached some settings pages that reflect the features and restrictions of the product with different settings, for you to consider.

Really high quality build for the price. I have experienced the clipping and audio cutting out that others have described but it was at extreme distances. The ear buds have been comfortable for all day wear and the dual pairing has been a life saver for WFH. Sound quality is okay for music but not mind blowing. The case really does give you several days of charging so they haven't been a nuisance with needing to be charged incessantly. Am able to use for about 10 hours a day before battery gets too low. The suggested app does help with sound tuning and eq and it's the only way to change the drivers.
