Review on 8 Sets of Colorful Call Earphones with Mic - Stereo Earbud Headphones Bass Enhanced (Black, White, Pink, Green) by Devin Pishey

For headphones under $4, the comfort and sound quality are quite decent. Taking a star off the 4 star rating because 1/3 to 1/2 of the units are broken in the most annoying way. Faulty devices cause my phone to mute the playback volume at random times. Please note that this is not an accidental pressing of the built-in mute button, the sound will decrease until it becomes silent. This also happens when I hold the phone away from my body and the headphones aren't touching anything other than the headphones in my ear and the jack in my phone.
