Review on 🎧 Chstarina Wireless Earbuds Sports - Bluetooth 5.1 IP7 Waterproof Earbuds with Ear Hook, Charging Case, 40H Playtime, Deep Bass, Noise Cancelling - Perfect for Gym, Running by Muharik Khalifa

sounded good for about 3 weeks and connected to my phone with no problems. Then, at week 4, the headphones stopped syncing with each other, creating some weird ear-to-ear sound effects. It's very difficult to have a conversation on the phone when you hear a person in one ear, and then an echo in the other, jumping back and forth. The only way to solve the problem is to disconnect the phone and then connect it again. Then everything is fine for about 20 minutes and starts to get out of step again. I've read other reviewers saying the same thing, but I was hoping it was just isolated cases or broken/early versions. If you're only going to plug in your headphones for a few minutes, that's fine. They are very comfortable. But if you need to be on them for more than a few minutes, they can be problematic. I would not recommend it.
