Some things were meant to be two.

Most music is mixed in stereo. The voice sits in the center and the music spreads out around you. But all portable speakers currently on the market are single boxes, meaning everything comes from one spot, and the space in the mix is gone.

Two speakers bring the air back to your music. Until now that would mean having to buy two objects you need to charge separately, manually pair, and pack together. CoAudio OneTwo sets that right.

CoAudio OneTwo is a single unit that opens and automatically pairs - a brand new category of portable audio - so you carry them as one yet still listen to the full stereo image of your music.

Music breathes again.

The sweet spot moves with you. Put one speaker on either side at your desk, on the balcony, or across a hotel room, and the center of the music is wherever you are.

A true stereo pair that packs down to one speaker.

01

Music needs air

Pull the two halves apart and both speakers wake up and connect to each other on their own. Once you’ve paired them with your phone, there’s no app you need to open and no stereo setup to repeat. Place them an arm's length apart, press play, and you’re in the middle of the music. When you’re done, slide them back together and drop the single unit in your bag.

02

One thing in your bag

Slide the two speakers back together and they lock into one unit that fits in a bag. One thing to charge over USB-C, one thing to pack, and a full day of playtime on a charge. Rated IP67, so rain, sand and spilled drinks are not a problem.

03

Built as a pair

Custom full-range drivers developed with SEAS in Norway and audio engineering with Sonavox in Canada, so the two speakers are matched to each other and produce one stereo image.
