ULT FIELD 1 Wireless Speaker - Black

The Sony ULT Field 1 is a portable, durable (IP67, shockproof) speaker ideal for outdoor use. It boasts long battery life (up to 28 hours 45 minutes) and a unique ULT mode for enhanced bass. However, the white cloth finish is prone to staining, and the sound quality is limited at higher volumes, lacking deep bass even with ULT mode engaged. The app's EQ is also limited.
