Dual passive radiators for making the bass sound good from a compact size

Two passive radiators are housed on the right and left sides of the cube-shaped compact body. These receive the air pressure generated from the 10W speaker units and reproduce substantial bass sound despite the compact size.

One-touch listening to play instant music

NFC (Near Field Communication) technology removes the need for wired connections and complex set-up sequences. Simply touch your NFC-enabled smartphone or other device* to the on-body N-mark and start your music. No NFC? No problem. You can also pair the devices manually in Bluetooth® settings. *See compatible devices

Stereo mode and Double mode for integrated use of two units

By connecting two SRS-X11 units via Bluetooth®, you can select audio reproduction using Stereo mode (stereo sound) or Double mode (same sound is output from two units simultaneously). In Stereo mode, one speaker acts as the left audio channel, and the other as the right — so you can enjoy balanced stereo sound with clear separation. Double mode reproduces identical sound over a broader area — making it a great way to pump music to every corner of your party.

Simplify communication with hands-free calling

Enjoy intuitive, hands-free calling wherever you are and whatever you’re doing. Simply pair your phone with the SRS-X11 via Bluetooth®, and you’re ready to make and take calls using the built-in speaker and microphone. Music automatically cuts out, so you can enjoy a clear line with minimal distraction while speaking to family and friends.

Silicone strap included

The SRS-X11 comes supplied with a silicone strap that is colour-coordinated with the colour of the body. This strap comes in handy when carrying the SRS-X11 around with you on the go, and can also be used to hang up the speaker after you return home for casual and fashionable storage.
