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.

After searching and trying many different types of earbuds, I finally found a great pair that works well for me. Based on my ears, Apple earpods do not work well at all. They do not stay in my ear no matter what I do.This is the first time I have ever heard of or tried EarFun. Over the past week, I have tried various models from Soundcore, JBL and TOZO. There was something that was just not right with those models. They either did not have wireless charging, or poor / bad sound, did not support Noise Cancelling, etc.Well ... boy was I surprised when I get the EarFun earbuds. I was very skeptical since I had such disappointing results from the other earbuds.The Good:------------------------------------- Sound Quality: These earbuds were very very good. Nice clean sound and great range from lowest bass registers to the highs.- The App: Nicely done App. Allowed full control including creating and saving personalized EQ preferences. I was able to tailor the sound to my exact liking.- Phone Audio: Great. I could clearly hear persons on the other end and everyone said my voice came through loud and clear.- Multiple Devices: These earbuds did support multiple devices and the App made it convenient to switch between them. Setting up multiple devices was great. Finally a product that has a simple process to add a second device.- Noise Cancelling: It just works. Stable and does not 'switch in/Out' like other models I have tried. Nothing spectacular about the ANC but not bad. The noise cancelling is not at the level where it could be used as hearing protection at a shooting range ... but they are not designed for this ... so not a negative at all.- Charging: These earbuds do provide for wireless charging. Surprising I have this in the 'Good' .. but I have tried many newer pricey models that do not offer this capability.- Fit: I generally wear medium bud cups. A few of the models I tried, even though they had mediums, did not fit well. These fit just right. Thus far, I have only worn them for a couple house ... so not sure what they will feel like after a full day ... but so far they are quite comfortable.The Not As Good - But still OK:------------------------------------- These earbuds do not stream sound simultaneously from both sources. It will stream sound from the 'active' source. If both sources are active at the same time, it will stream from the source that was connected 'first' during the set-up phase. Therefore, probably a good idea to make sure your 'main / primary' source is set-up first.- Touch controls seemed consistent. I need more time with these to determine how good it is. Typically, I generally only need touch controls for volume up/down and pause/play. These earbuds offer additional controls like (previous / next selection, ANC settings, etc)The Bad:------------------------------------- Multiple sources: The multi-source capability works quite well. The only issue is, once the primary source is playing sound, it does not pause the other source. That would be nice ... but it's not all that bad really.

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.
