The verdict

The Sony ULT Field 7 may not be the smallest or most affordable Bluetooth speaker out there, but it makes up for it with a feature set that rivals much larger party boxes. If you entertain regularly, its bass-forward sound, rugged design, and wide range of connection options make it a serious contender for your next backyard BBQ or tailgater.
