Review on CUIZI Wireless Earbuds Bluetooth Headphones, 5.0 HD Stereo Sound Wireless Headset, Waterproof IPX7, Built-in Mic, Noise Canceling, Long Playtime, Charging Case by Dezz Watson

Quickly connects to my phone via Bluetooth. The sound quality is good. Waterproof in the shower. Last week, while shoveling snow, my earphone fell out of my ear and I didn't see or hear it land. I couldn't find it anywhere - I even tried using my metal detector to no avail (they have to use the metal to build concrete driveways). I gave up trying to find it, thinking the car or trunk had crushed it in the mud and I might find it ruined next spring. I checked again after 4-5 frosty wet days as the snow had melted a bit and here it is! It's waterproof and hasn't been exposed to salt so I connected it to the charger where it charged fully and it's been working like new ever since! I replaced the silicone ear cup with a size larger and it held in place better.
