[Upgrade] True Wireless Earbuds,Bluetooth Earphones Bluetooth 5.0 Earbuds IPX7 Waterproof Headphones Auto Pairing in-Ear Stereo 90H Cycle Play Time Wireless Headset with 3350mAh Charging Case

I bought these during Prime Week 2019 at 30% off. Seemed like a great deal. It was not. I use a simple Bluetooth transmitter connected to the Aux port of a Marantz receiver to listen to TV when my wife is sleeping. I've been using Bose QC35s for several years. No better noise cancelling headphones than them. But decided to try true wireless since sound quality was not an issue for an hour or two of TV. Followed the charging instructions. First use after 30 minutes of fiddling around with the earphones, I got them to connect. Pain in the patoot. But I assumed once pairing was 'learned', subsequent pairing would be seamless. The earphones never paired again. I went through the troubleshooting checklist provided. I heard the earphones pairing with each other L/R. Lights were blinking. But nothing. Pairing is either easy or the earphones are worthless. Returned for a refund.

Overall good ear buds. I am not an audiophile and I did not buy these for listening to hours of music. I bought them for when I go running. I managed to kill a few other wireless headphones that are connected to each other before this. I only use the left bud when I run so I am not completely cut off from my surroundings so the right side would of the other headphones would rest on my shoulder. I guess the sweat would get into the charging port and kill them. That’s why I went with these buds.Sound quality is good enough for my needs. I wasn’t blown away by it but I didn’t have the impression that it was bad. I tested with both in my ears listening to music and video. I didn’t notice any lag for the video. Connection to my phone is usually straightforward but can be a bit finicky to the point that I have to reboot my phone to get them to work. But I haven’t figured out the exact cause of the issues so it might not be the buds’ fault.The fit is good for my ears. I do go running with them and they’ve fallen out a couple of times but I was fiddling with them shortly before so that might be my fault. The touch controls are easy to activate accidentally when I try to adjust the buds in my ears. I end up pausing the music when trying to resecure them in my ear. So far my sweaty runs haven’t killed them.I hardly receive calls on my phone ever and one day it started ringing while listening to music on my run. I picked up the call and I was able to hear my caller clearly. However he said there was a lot of background noise coming from my end.Battery life is good but I don’t use them for hours on end. I have used them for a couple of hours straight and they lasted fine. Charging the buds is very convenient with battery case. It is a little hard to take the buds out of the case because they are held in magnetically and they are small so it’s not easy to pull them out. I hardly have to charge the battery case.

I've thoroughly tested these earbuds and I am quite surprised and very happy with their performance. While battery life does depend on the volume at which the music is being played, it seems at full volume between 2.5 -3 hours is pretty accurate, but I had mine around 60% volume and was still at 40% battery life pushing 4 hours. And from 40% to a full charge in the case didn't take very lone (full drain to full charge is about 1.5 hours, but I've not depleted the battery on mine yet so I cannot fully verify, but seems accurate). Works flawlessly with my iPhone SE 2, Siri capable and seems to be around 95-97 dB max, but since they're third party hardware the Health app can only guesstimate. Great HD sound, great high fidelity with rich bass that doesn't distort, tickle your eardrums and make ya sneeze! The nanocoating gives the buds a nice soft touch and the power bank/case has a solid feel to it as well. The touch buttons are responsive and easy to use. Fantastic price for a fantastic product! Definitely recommend (already have to a few people).

Very nice product. It's compatible with my phone's sound settings which is helpful with those who are hard of hearing. It connects to the phone quickly and easily, and the earphones have easy to understand settings that allows you to skip, replay, and pause/play music.The case is not fall proof though, so if it falls the buds will fall out easily.Other than that the sound quality is great, it can get pretty loud, noise cancellation is also good, and battery life is pretty good. Can last from 8 hours continuous play to 2 days off and on play.Update 05/06/2020: I liked the last one I bought but I gave it to my daughter so I bought another one for me. It arrived 2 days ahead of schedule. I noticed that one ear bud depletes very quickly. I thought because the clear film to protect the charging port prevented it from charging. I removed the film and charged overnight. After a complete charge, I used it for one minute then returned it to the base. One ear bud took about 5 minutes to recharge. Upon using both for 3 hours, that same ear bud chimed in saying battery is low. I put it back onto the charger and only using one bud. May send this pair back
