The verdict

While the ULT Field 3 packs a decent low-end punch in ULT mode, it’s a bit of a one-trick pony, sound-wise. If you’re not a fan of the ULT EQ setting, your only option is to use the custom EQ, which won’t give you the same bass-heavy performance—leaving you with a less-than-satisfying overall sound.

✓Liked: IP67, Long battery life, ULT setting sound quality, Shoulder strap included

✕Could be better: Large enclosure, Strap can be challenging to remove, Custom EQ cannot match ULT bass levels

Owners

How we verify owners

Nobody who owns the Sony ULT Field 3 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.
