The Pro Ears : Stealth 28 HT 

The Pro Ears : Stealth 28 HT behind-the-head electronic hearing protector delivers a better fit while wearing glasses, hats or for those with longer hair. It fits snug, but not tight, so you feel secure while avoiding nasty compression headaches.
Very light weight and evenly balanced so you barely know you are wearing
electronic hearing protection.
The audio is designed for people who enjoy listening to music and need
hearing protection. Music enjoyment should not be an afterthought. 10 mm
diameter speakers, dual drivers and a top line Bluetooth chip all result in
crisper sounding highs and deeper lows.
Pro Ears is known for with their proprietary DLSC technology. The hybrid
analog/digital system ensures your safety from loud sounds and you can
enjoy more natural sounding amplification.
The omnidirectional microphones provide situational awareness so you
know exactly where a sound is coming from. Noise isolation helps provide
clearer phone calls.
All of this in a very small ear bud because the electronics are all in the
controls tucked securely behind your head. Universal fit for tiny adolescents
to large adults with our unique coil system headband.
