Sony ULT Field 1 Review: Would Owners Buy It Again?
Disclosure: As an Amazon Associate I earn from qualifying purchases. If you buy through links on this page we may earn a commission at no extra cost to you. How this review was made: We did not test this speaker in person. This verdict is based on our analysis of two independent expert reviews, listed at the end. We did not find enough independent long-term owner data to judge durability over years, and say so below. Our method.
A good small outdoor speaker, not a party speaker
Reviewers agree the Field 1 is compact, IP67 rated and good for beach or park outings, with a ULT mode that adds noticeable bass. They also agree on the limits: mono sound, distortion on heavy bass at high volume, a basic app and an off-white finish that gets dirty. One test scored it a modest 6.1 out of 10. It suits casual, portable use; anyone wanting big sound should look at larger speakers.

- want a small, rugged speaker for bags, trips and the beach
- listen at moderate volume outdoors or in small gatherings
- value long battery life with the bass boost off
Skip it if you…
- want loud, room-filling or party-level sound
- want detailed EQ control in the app
- dislike light-colored gear that scuffs easily
The Sony ULT Field 1 is a compact portable Bluetooth speaker with an IP67 dust and water rating and a carry strap. Its ULT button boosts bass, and it can take calls through a built-in microphone.
Independent coverage we could read was limited to a couple of detailed reviews, so we flag where evidence is thin.

What reviewers like
What reviewers criticise
How it holds up over time
Sony rates it for drops of about 1.2 metres, and SoundGuys expects it to survive ordinary drops but warns harder surfaces could damage it. We found no multi-year durability data, so long-term reliability is unconfirmed.
Tips from reviewers
- Turn ULT off when you want longer battery life.
- Keep volume moderate on bass-heavy tracks to avoid distortion.
- Rinse and dry the USB-C plug area and keep the rubber plug closed to protect the water rating.
- Pair two units through the app if you want stereo.
