Meet the Yuni

The Yuni is the world's first true single-sided stereo headphone. Initially designed for listeners with single-sided deafness (SSD) / unilateral hearing loss (UHL), the Yuni has also proven popular among users who need to keep one ear open while listening to music but still want to enjoy stereo sound.

The Yuni uses a revolutionary system of vertical stereo spacing, which places one transducer above the user's ear opening and the other below the ear opening. This technology results in the user's ability to hear 100% of their audio, distinguish between the two stereo channels with a single ear, and hear stereo panning between the two channels.

The first-generation Yuni launched in 2013. We launched the Yuni V2 in 2024, updated with the latest technology and improved to incorporate the numerous suggestions we have received over the years from our users.

The Yuni V2 is a Bluetooth-enabled (with optional 3.5mm cord) single-sided stereo headphone with both stereo channels in a single side, one above and one below the ear opening, so the brain perceives them as two separate sound sources. This way, you get stereo depth, localization, and panning just like you would with stereo, but using just one ear.

Though designed for listeners with SSD / UHL, other users who just want to keep one ear free while they listen to music – such as while working, walking, biking, DJing, or recording music – have also found the Yuni useful over the years.
