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 Jenny Maestas

Fairly easy to set up, sound quality is satisfactory. I didn't expect anything better for $20 and got what I expected. They don't handle high volumes well, but at reasonable levels they sound great. My only criticism of them is that they don't come with any instructions at all. If you've never paired items via Bluetooth before, you won't get instructions on how to do it. I still can't figure out all the declared functions, again due to missing instructions.
