TL;DR: Sony’s ULT Field 3 delivers strong bass, long battery life, and IP67 durability in a compact Bluetooth speaker — now $119.99 for an open-box unit.
Portable Bluetooth speakers often promise big sound, but many struggle to balance volume, clarity, and durability. Sony’s ULT FIELD 3 focuses on the fundamentals — strong low-end performance, long battery life, and reliable build quality in a compact form. The open-box Sony ULT FIELD 3 Speaker is currently available for $119.99, down from its $209.99 retail price.
The speaker is tuned for impact without sacrificing clarity. Sony’s dedicated ULT button boosts bass on demand, while a two-way speaker design separates lows and highs to keep audio balanced at higher volumes. For more control, the Sony Sound Connect app includes a 7-band equalizer, letting users dial in sound profiles for music, podcasts, or video.
Battery life is rated at up to 24 hours per charge, with quick-charge support providing several hours of playback from a short charge session. Bluetooth 5.2 delivers stable connections across phones, tablets, and laptops, and Party Connect allows compatible Sony speakers to sync for larger setups.
The ULT FIELD 3 is built to travel. An IP67 rating protects against dust and water exposure, and its compact design with an included strap makes it easy to carry without adding bulk. Its open-box label means it is a brand-new item, but was either excess inventory or returned and repackaged.
