Sony ULT FIELD 3 review: what the specs say
Rustproof and shockproof with a real bass button — built for the beach. At $199.99, Sony's 2025 model sits in the middle of the range — the bluetooth Speakers we compare run from $34.99 to $549.95. It scores 7.8/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Durability at 9.5/10 — IP rating, drop resistance and whether it floats. The weakest is Features at 7.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: bluetooth 5.2 with no LDAC, which is odd on a Sony product; and sony publishes no power rating. Every specification on this page comes from Sony's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
