Sony GTK-XB90 High-Power Portable Audio System with Bluetooth

Bring true energy to your party with EXTRA BASS beats and party lights from the Sony GTK-XB90 High-Power Portable Bluetooth Audio System. Incredible Infinity Mirror lighting takes visual effects to the next level, and a rechargeable battery lets you hold parties anywhere.

EXTRA BASS Technology

Bring the dance floor to life by activating Extra Bass. It enhances the low frequencies of the track, for beats that get everyone moving. Convenient carrying handles make it easy to transport your GTK-XB90 from party to party.

Infinity Mirror Lighting

Create an instant club experience, with pulsing strobe lights and colored speaker lights that change with the music. Infinity mirrors are positioned around the speaker edges, bouncing light back and forth continuously to create an energizing party atmosphere.

Wireless Connectivity

Near Field Communication (NFC) and Bluetooth technology remove the need for wired connections and complex set-up sequences. Simply touch your NFC enabled device to the headphones for a quick, seamless connection, and then start streaming your music collection. No NFC? No problem. Connect via Bluetooth and you’re ready to go. Connect up to 10 compatible speakers with Wireless Party Chain for even more audio power and an exciting party atmosphere with synchronized lights. It's all done with Bluetooth technology, so you don't need to use any connecting cables.

Digital Sound Enhancement Engine

Boost the quality of your compressed music files. When an original music source is compressed, it loses the high-frequency elements that add detail and richness to your favorite tracks. The Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce high-quality sound that’s closer to the original CD recording.


Unique to Sony, ClearAudio+ automatically adjusts sound settings for an enriching listening experience. By bringing together expertise in digital signal processing technologies, ClearAudio+ is able to optimize audio to deliver a consistently clear, high-quality sound, whether you’re gaming or enjoying music and movies.

Control the Party with Sony Music Center App

Run the party from the dance floor using the Sony Music Center app. It lets you choose tracks, change sound settings and create playlists, all from your phone. The Fiestable plug-in puts you in charge of the light colors and lets you adjust EQ or activate DJ control. Make changes with a flick of your wrist, thanks to the intuitive motion control.

Up to 16 Hours of Music Playback

Got no mains electricity? The Sony High Power Portable Audio System's built-in rechargeable battery powers your party for 16 hours with the speaker lights off and the volume turned to level 16. Even at full volume with Extra Bass sound and lighting on, you can party for 3 hours. If you’re running low, just activate stamina mode to make your battery last longer (up to 4.5 hours).
