Review on 🎧 AICase TWS Wireless Headphones - Bluetooth 5.0, Mini Sweatproof Sport Earbuds with Mic, Wireless Charging Case - For Android and iOS Smartphones - HQB-U by Cynthia Beauchene

I had bluetooth headphones but lost them. I received this as a replacement. You are terrible. The distance from my phone is 4 feet then the sounds cut off. The sound also turns on and off when walking or cycling (mostly when I'm not standing still they don't work). The sound disappears from one or the other earphone several times a minute, even when standing still. And when both headphones work, the sound is often out of sync and becomes a strange echo between the two headphones.
