Can I use the CS-M1 to watch video or play games?

Absolutely! The Exos-9 can deliver all the power and depth of a “true” 2.1 system in a single unit. Depending on your device, you may find that using the 3.5mm aux-in jack works best. This is because some devices create a small delay when streaming over Bluetooth, which can slightly throw off the viewing experience. Your mileage may vary, but using the aux-in jack can sometimes create a better viewing experience.

How do I set up the CS-M1?

All you need is something to play music from, the Exos-9, and maybe a wall outlet. Take the Exos-9 out of the box, plug it in, switch it on, and either pair your phone/tablet/PC with the Exos via Bluetooth, or plug an audio source into the Aux-in jack on the back. From there, enjoy the sound! It’s as easy as that, you should be up and running within a minute.

With a large, powerful, bass-reflex speaker like the Exos-9, where you put the speaker can affect the sound. If you place the Exos-9 near a wall or in a corner, the bass may increase. You can use the equalizer to adjust it if necessary.

What’s your warranty policy?

We offer a 1-year limited warranty.

Will the CS-M1 work with my phone or device?

The CS-M1 will not work wirelessly with Bluetooth audio-compatible devices. It will work only with micro cassette tapes and AM/FM radio channels.
