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.

✓Liked: Sound quality, Connection options, Light show

✕Could be better: Large, AC charge only, 7-band EQ should be more powerful

Owners

How we verify owners

Nobody who owns the Sony ULT Field 7 has written in yet.

Owner reviews are not paid for, not solicited from specific owners, and not rewritten by us: at most we proofread typos, which is shown on the review’s own page and which the author can undo. The commission SoundGuys may earn on this page comes from retail links, never from owner reviews.
