Is the ULT FIELD 1 good for outdoor use?

Yes. It has an IP67 rating for water and dust, plus shock and rust resistance, so it handles beach, pool and trail use well.

Does it have a bass boost?

Yes. A dedicated ULT button boosts low end. It adds punch but can muddy vocals at high volume.

Can I pair two for stereo sound?

The speaker is a single unit with one driver, so it does not offer true stereo separation on its own.

What Bluetooth codecs does it support?

SBC and AAC only. There is no LDAC or aptX, so hi-res codecs are not available.

Does it work with voice assistants?

It has a built-in microphone and works with Google Assistant on paired Android devices.

It charges over USB-C. No power adapter is included in the box.

Our take on the Sony ULT FIELD 1 Waterproof Portable Bluetooth Speaker

The Sony ULT FIELD 1 is a compact portable Bluetooth speaker with a 30 W driver and a dedicated ULT bass boost button. It is built for outdoor use, with an IP67 rating for water and dust, plus shock and rust resistance, and a multi-way strap for hanging it on a bag or bike. Its main rivals are the JBL Flip and Charge lines and the Bose SoundLink Flex; the Sony is smaller than a Charge and trades some loudness for portability. Owners rate it highly for ruggedness and punchy bass, but note that it is a single speaker, so stereo separation is limited.
