Review on Rugged Radios H41-CF Carbon Fiber Behind The Head Two Way Radio Headset: Volume Control, 3.5mm Jack for Music / MP3 Players by Roberto Manzer

This is a great product for the money. They are ideal as hearing protection. The sound quality is excellent for both the 5-pin connector and the AUX adapter. The microphone mouthpiece works great too. Picks up voice clearly and virtually eliminates background noise. The only thing I don't like is the volume control. You only have the volume control through the 5-pin connector. You need to control the volume through the AUX port from whatever device you plugged into it.
