We set out to design the perfect audio wearable,

and leave old fashioned designs behind.

Ultra low profile

Behind-the-ear design makes Hy virtually invisible from the front and fits beautifully to the contour of your ears

Huge battery life

Hy has over 2.5x the battery capacity of other leading wireless earbuds¹, for up to 12 hours playback

Natural sound

Our wishbone driver² uses a hybrid of air and bone conduction to give you amazing sound, without blocking your ears

All day wear

Place Hy in your ears, and forget it's there until you want to make a call or listen to music

¹ Hy (520mAh) vs. Bragi The Dash (200mAh) 

² GB Patent Application No. 1614883.5



Hy are wireless headphones for music, calls and voice actions. Hy doesn't block your natural hearing, so you can wear them all day and forget they're even there…
