The Sony ULT FIELD 7 SRS-ULT70 is a wireless portable party speaker built for music, outdoor entertainment and karaoke. It combines ULT POWER SOUND with two selectable bass modes, ULT1 and ULT2, giving you control over the bass-focused sound profile according to your listening preference.
Its two woofer units and two tweeter units work together with Sony's X-Balanced Speaker Unit technology to deliver a full-range listening experience. The speaker also features a 7-band custom EQ and Sound Field Optimization, allowing the sound to be adjusted for different listening preferences and environments.
For extended use, the built-in rechargeable battery provides up to approximately 30 hours of playback under specified conditions. IP67 water and dust protection, a carrying handle, colourful lighting, karaoke connectivity, USB smartphone charging and Party Connect make the ULT FIELD 7 suitable for both indoor gatherings and outdoor entertainment.
Key Features
ULT POWER SOUND with Two Bass Modes
Different types of music can benefit from different bass levels. The ULT button provides two sound modes, ULT1 and ULT2, allowing you to select the bass-enhanced profile that suits your listening preference.
X-Balanced Speaker Unit
The ULT FIELD 7 uses an X-Balanced Speaker Unit for its woofer section. This speaker construction is paired with two woofer units and two tweeter units to support the speaker's overall sound reproduction.
7-Band Custom EQ
A fixed sound profile may not suit every listener or music style. The 7-band custom EQ allows you to adjust the sound profile to your personal preference.
30-Hour Battery Life
Frequent charging can interrupt longer listening sessions. The built-in rechargeable battery provides approximately 30 hours of battery life under specified playback conditions, while 10 minutes of charging can provide approximately 3 hours of playback under specified conditions.
IP67 Water & Dust Protection
Outdoor use can expose a speaker to water and dust. The ULT FIELD 7 carries an IP67 protection rating, providing water and dust protection for suitable outdoor use.
Colourful Party Lighting
Music-focused gatherings can benefit from synchronized visual effects. The ULT FIELD 7 features colourful lighting that adds a visual element to the listening experience.
Karaoke & Guitar/MIC Input
The speaker includes a dedicated 6.3 mm Guitar/MIC input for karaoke and guitar use. This makes it possible to connect compatible microphones or a guitar directly to the speaker.
Party Connect & Stereo Pair
A single speaker may not always be enough for a larger listening environment. Party Connect and Stereo Pair allow compatible Sony speakers to be linked for a larger sound setup.
Bluetooth 5.2 with LDAC
Wireless music playback is supported through Bluetooth 5.2. The speaker supports SBC, AAC and LDAC codecs, with LDAC available when used with compatible devices.
USB Smartphone Charging
Long listening sessions can also drain a connected smartphone. The built-in USB power port can provide power to a compatible smartphone while the speaker is being used.
Portable Handle Design
Moving a larger party speaker between locations can be inconvenient. The ULT FIELD 7 features a comfortable carrying handle to make transportation easier.
