Review on Bluetooth KKUYI Earphones Waterproof Headphones by Joey Makarovski

I had never heard of this brand before but was pleasantly surprised at how good they are. It has all the features you are looking for in a true wireless headphone: Bluetooth 5.0, wireless charging case, Apt-X, IPX5, touch controls, built-in microphone, deep bass, powerful sound, long playback time and surprisingly good quality. looks good and is well built. I've been using it regularly for over a month. They fit my ear very comfortably (with medium sized earbuds) and stay secure even when I walk or eat. The touch function works very well. When it comes to sound quality, remember that the sound quality of your headphones is highly dependent on how well they fit your ears. I have a pair of Bose wired headphones (SoundSport) which are always the gold standard by which I rate all my other headphones. I also have Bose noise canceling headphones (QC25) that I use to evaluate other headphones. Headphones are much less sensitive to how you put them on to get good sound. With headphones, even my Bose SoundSport, I rock them a little each time I use them to get into the position that produces the best sound. The same applies to KKUI. It took me less than a minute to determine the best position on first use. Now I'm comparing KKUYI to my Bose SoundSport after finding the best possible position with the best fit for both - I used "Welcome to the Machine" for comparison which has a good mix of bass, treble and vocals. KKUYI really has a bright bass pronunciation as advertised, treble and vocals are as crisp and clear as Bose. However, if I loosen the fit a bit, I can reduce the amount of bass from KKUYI, but it will also reduce the overall volume, although I do get slightly more balanced bass/treble/vocal. Personally, I prefer Bose's balanced bass/treble/vocals that don't shake too much required when I put it on Bose, is also a bit higher in the highs, but only if I listen very carefully, KKUYI is never objectionable. Overall, the sound quality of KKUYI can match or surpass any wired or wireless headphone under $50, but oh no better than my Bose. I particularly like the wireless charging function. While charging, the green indicator on the case "breathes” (turns on and off slowly, watch the video). When fully charged, the green indicator light will be on (see figure). I used the headphones continuously for 4-5 hours and the battery still holds a charge without having to put them back into the charging case. Overall, the equipment is rich, the sound quality is very good and the workmanship is impeccable.
