Sony has unveiled two of the best wireless-powered outdoor party speakers with enhanced bass for powerful music reproduction: the ULT Field 3 and 5. Both speakers actively monitor ambient noise to compensate for clearer music playback.

Sony has launched two new ULT Power Sound series wireless portable speakers: the ULT Field 3 and the ULT Field 5. Both powerful outdoor Bluetooth speakers feature enhanced bass and a carrying strap for optimal portability.
Two identical speakers can be paired for stereo output, while up to 100 Party Connect-enabled speakers can be synchronized to play the same music throughout a large venue. The Field 3 features a single-stage bass booster and a 7-band EQ, while the Field 5 has two stages and a 10-band EQ. Both units automatically adjust the music to compensate for ambient noise and improve clarity.
The wireless outdoor speakers portable model supports Bluetooth 5.2 multipoint connections with two devices simultaneously. They can be controlled from a smartphone running the Sony Sound Connect app, and EQ, lighting, and other settings can be adjusted. The Field 5 features a 360° party light that syncs to the music.

The ULT Field 3 has a battery life of 24 hours, and the ULT Field 5 has 25 hours. You can quickly charge both in 10 minutes, adding 2 hours of battery life. You can also use them as USB-C power banks to charge smartphones and other devices. The speaker’s app can check the battery level from any smartphone.
