Sony ULT FIELD 7 Wireless Speaker

It's all about the bass with the Sony ULT FIELD 7 Wireless Speaker. Using their X-Balanced speaker unit, rich bass sound is provided from a pair of 4.5" non-circular woofers and passive radiators on each end of the ULT FIELD 7's tube-shaped body. If you still need more, press the ULT button twice to select from two levels of bass: deep low end or powerful punchy bass response. Part of the ULT POWER SOUND series, the ULT FIELD 7 is made for outdoor gatherings and parties that go to the break of dawn. IP67-rated, the ULT FIELD 7 can handle dust and water, and up to 30 hours of playback are available on a full charge. Further enhancing your hangout or party are multi-color LED ring lights on each end, and an input for an optional guitar or karaoke microphone.
