Key Features

ULT POWER SOUND with Two Bass Modes

When you want stronger low-frequency impact, ULT POWER SOUND provides two bass-emphasis modes: ULT1 and ULT2. This lets you select between different bass-focused sound experiences depending on the music and listening environment.

360° Party Sound

Sound is not limited to a single listening position. The 360° Party Sound feature helps spread music around the room, making it suitable for group listening and party environments.

Up to 25 Hours of Battery Life

Long events can be interrupted by frequent charging. The internal rechargeable battery provides approximately 25 hours of battery life, allowing extended use without continuously relying on an AC connection.

Easy Movement with Handle and Castors

A speaker of this size can be difficult to reposition manually. The integrated handle and large castors make moving the ULT TOWER 9 more convenient between rooms or party locations.

Karaoke and Guitar Inputs

The speaker includes a dedicated microphone input and a combined guitar/microphone input. This allows karaoke, duet-style microphone use and guitar-based entertainment without requiring a separate speaker system.

Echo and Key Controls

Karaoke vocals can require more control than standard music playback. Echo and Key Controls on the top panel allow adjustments to supported vocal effects while performing.

TV Sound Booster

The TV Sound Booster feature allows the speaker to be used to enhance TV audio. This provides an additional way to use the ULT TOWER 9 beyond music and party playback.

10-Band Custom EQ

Different types of music can benefit from different sound profiles. The 10-band custom EQ provides more detailed control over the speaker's sound according to listening preference.

Bluetooth 5.3 with LDAC

Wireless playback is supported through Bluetooth 5.3, with SBC, AAC and LDAC codecs supported. This provides flexible wireless connectivity with compatible devices.

Party Connect and Stereo Pair

The speaker supports both Party Connect and Stereo Pair functions. Compatible Sony speakers can therefore be connected in supported configurations for expanded listening setups.

USB Smartphone Power Output

Running out of smartphone battery can be inconvenient during long events. The built-in USB power port can provide power to a compatible smartphone while you continue using the speaker.

Splashproof Top Surface

The top surface is specified as splashproof, adding protection against splashes in suitable environments. The speaker is not specified as fully waterproof.
