The Sony ULT Tower 10 is a powerful wireless party speaker designed to transform any space into a live concert venue with massive bass, 360-degree sound, and synchronized party lighting. The speaker features an X-Balanced Speaker Unit with an approximately 320mm x 320mm large woofer that delivers deep, powerful bass through Sony's ULT POWER SOUND technology. Press the ULT button to choose between two bass modes: ULT1 for deeper, low-frequency bass that makes your heart tremble, or ULT2 for powerful, punchy bass that gets you dancing.

Four tweeters positioned around the speaker deliver clear audio to every corner of the room, while two mid-range speakers ensure vocal clarity. The 360-degree party light system creates a vibrant festival atmosphere with lighting that synchronizes to the music beat. The speaker includes a wireless microphone for instant karaoke, with echo and key controls on the touch panel, plus inputs for an additional wired microphone or guitar so you can use it as an amplifier.

Key features include TV Sound Booster technology that enhances audio from your television using the optical input, Bluetooth connectivity with Fast Pair and multipoint connection to pair two devices simultaneously, and a 7-band equalizer controlled through the Sony Music Center app. The speaker supports Party Connect to link up to 100 compatible speakers, or connect two ULT Tower 10 speakers for true stereo sound. Sound Field Optimization automatically adjusts settings based on ambient noise to maintain clear audio quality.

The IP64-rated splash-resistant top panel protects against spills during parties. Built for mobility, the speaker features a sturdy handle and large wheels for easy transport. Additional features include USB playback and device charging, control via Sony Music Center and Fiestable apps, Bluetooth standby mode, and auto-standby power saving. The speaker uses recycled plastic materials as part of Sony's commitment to achieving zero environmental footprint by 2050.
