Review on 🎧 COUMI Bluetooth Headset 5.0 - Wireless Earpiece with Noise Cancellation Mic for Business, Office, and Driving - Compatible with Android by Tyler Kota

Microphones do not work. I have contacted the seller several times, he replies but does not offer any help. The clay is almost never used. It adapts well to the ear with the right ribbed tip. Nozzles are difficult to install. I can't say anything about the battery life because it doesn't work properly and is therefore unusable. I do NOT recommend this junk.
