Verdict

The Sony ULT Field 3 is a rugged, 1.2 kg portable Bluetooth 5.2 speaker featuring a 2-way active design with a dedicated woofer, a 0.7-inch tweeter, and dual passive radiators. Its defining characteristic is the dedicated ULT button for dynamic bass reinforcement, alongside an IP67 waterproof, dustproof, and shockproof rating, custom 7-band EQ manipulation via the companion app, up to 24-hour battery life with 10-minute quick charging, and a dual-purpose USB-C port that functions as a power bank. Main pros include its robust outdoor-friendly build, handy detachable shoulder strap, multipoint connectivity, and authoritative bass presence at moderate volumes. However, cons include audible audio compression and low-end distortion when pushed to max volume, downmixed mono-only playback on a single unit, a lack of high-res audio codec support (SBC and AAC only), and a lack of a 3.5mm auxiliary input for physical audio connections.

What customers dislike about Sony Ult Field 3?

  • Underwhelming and weak default bass response when the 'ULT' mode is switched off.
  • Restricted to downmixed mono playback on its own, failing to deliver a true stereo soundstage unless paired with a second unit.
  • Noticeable audio compression and slight distortion when pushed to its maximum volume levels.
  • Lacks support for high-resolution Bluetooth audio codecs, missing out on Sony's premium LDAC standard.
  • No physical auxiliary or wired audio input compatibility through its single USB-C port.
  • Slightly bulkier and less packable into standard travel bags compared to some direct competitors.
