Sony ULT FIELD 3 is a portable Bluetooth speaker with a bass-boosting ULT button, app-based equalisation and a detachable shoulder strap. Its listed 24-hour battery life and IP67 protection suit travel and outdoor listening, while its 1.2 kg weight is worth factoring in for longer carry distances.

Pros and cons
Pros
- A dedicated bass mode and app-based 7-band EQ provide two ways to adjust sound.
- The claimed 24-hour battery life, quick-charge playback claim and phone-charging function are useful away from a mains supply.
- The strap, upright or horizontal placement and stated IP67 protection make it adaptable for travel and outdoor listening.
- Hands-free calling and noise-adjusting Sound Field Optimisation are listed features.
Cons
- At 1.2 kg, it is portable but not a negligible load for extended carrying.
- The ULT mode boosts bass, which may not suit listeners seeking a more neutral presentation.
