EXTRA BASS™ is better than ever with hardware improvements to reproduce powerful sound with high sound pressure. With a long battery life, three different power supply modes to make the party last longer and the option to hook up even more devices wirelessly, these speakers are something you can shout about.

The same EXTRA BASS™ technology but now with up to 14 hours of built in battery life allows you to take this mighty GTK-XB60 speaker with you if you want to party on the go with the option to switch between battery modes making it easy to keep the party going with AC, Battery and Stamina mode.

But why stop at one? With Wireless Party Chain, you can to connect up to 10 EXTRA BASS™ speakers[1], allowing you to bring more power to the party. Let your friends join in the fun with multi device connections, up to three smartphones at once, so you can all play DJ. And with a mic input, you can now sing along for those late-night karaoke sessions!

Line, speaker and strobe lighting give your party the real edge with the lighting adapting to all the music you love, from EDM to grime to pop, the XB60 can sync to any song. Customize your lighting options with the Sony Music Center & Fiestable apps on your mobile device, putting all the power of this lightweight, compact but mighty speaker in your hands!

Feel the bass vibrate with the XB90

The EXTRA BASS™ GTK-XB90 has infinity mirror lighting to replicate festival lighting, pair that with higher sound pressure than ever and you can imagine you’re watching your favourite DJ live.

The bigger brother to the XB60, the GTK-XB90 can last for up to 16 hours on just 4 hours charge, using one of the three modes: AC, Battery or Stamina to save battery life and keep the party going longer.

More party features on the Fiestable app such as customizable lighting, motion control, sampler effects and DJ control mean that you are in control of the party and how your speaker acts. Alternatively, let the XB90 do its thing as it syncs the lighting whilst you party away or increase the fun with Wireless Party Chain so all your friends can connect their EXTRA BASS™ speakers to yours[2], for a huge party wherever you are.
