Sony's Ult Field 1 portable Bluetooth speaker has hit its lowest ever price during Prime Day, sliding from the original $139.99 to just $78 after a 44% discount. The Seattle‑based reviewer notes the deal makes the otherwise mid‑range speaker a bargain for anyone looking to bring loud, bass‑rich audio to beach outings or backyard gatherings.

Weighing under a kilogram, the Field 1 packs a 12‑hour battery, IP67 water‑ and dust‑resistance, and a dedicated ULT button that activates side passive radiators for extra bass. While it remains a single‑driver unit, users can link two speakers for true stereo sound, a useful trick given the steep price point. It also supports Bluetooth 5.0 for a reliable connection up to 30 feet.

For users craving more power, Sony offers the newer Ult Field 3, which adds a 7‑band equalizer, 24‑hour playtime, fast charging and the ability to chain up to 100 compatible speakers. At the price, the Field 1 delivers volume for most casual outings, making it a sensible choice for budget listeners who want performance. Its USB‑C port can double as a power bank for devices.
