ULT Field 3

Reviewer verdict

Across 16 YouTube reviews, the Sony ULT Field 3 earns an Index score of 4.2/5, ranking #14 among Bluetooth Speakers. Reviewers most often praise its features, sound quality, portability, while the most common criticisms concern features, battery life.

The ULT Field 3 is repeatedly praised for packing a rich set of features and solid ecosystem integration, with many reviewers (73 mentions) highlighting the Sony Sound Connect app, Party Connect for linking up to 100 speakers, a seven-band EQ, USB-C in/out powerbank capability, and handy physical controls including an alt/Extra Bass button. Reviewers also commonly commend its sound quality (41 mentions) — loud, clear output with punchy bass from dual passive radiators and an angled tweeter, plus a distinct Alt mode that boosts presence — and its portability (33 mentions) via a lightweight, well-balanced chassis and durable shoulder strap. Battery life and charging received frequent positive notes (32 mentions) for long runtimes at moderate volumes, quick-charge capability, and a battery care mode. The speaker’s rugged build and IP67-rated durability (29 mentions), premium-feeling design and color options (25 mentions), and reliable Bluetooth connectivity and pairing features (8 mentions) round out what most reviewers liked.

Criticisms cluster around missing or limited features (27 mentions), notably the lack of position IQ and LDAC support, limited lighting/customization and only a single, non-programmable Alt mode, plus absence of some higher-end bells and whistles found on larger models. Battery performance at max volume is a common caveat (10 mentions), with real-world runtimes dropping to roughly five hours at full volume and advertised 24-hour figures applying only at much lower volume levels. A smaller set of reviewers noted sound tradeoffs (9 mentions) such as bass compression or a mids dip at loud levels and less bass depth than the larger Field 5, and a few usability niggles around strap removal, the rubber charging flap, and the white color option staining more easily.
