Is the Sony ULT Field 1 waterproof?

Yes. It carries an IP67 rating, so it is dust-tight and can be submerged briefly. Sony also rates it shockproof for drops.

How does it compare with the Sony SRS-XB100?

The ULT Field 1 is larger and rated at 30 W, so it plays louder with more bass. The XB100 is smaller and cheaper but has less output.

Can I pair two ULT Field 1 speakers for stereo?

Yes. You can link two units for stereo sound through the Sound Connect app.

Does it have a built-in voice assistant?

No. It has no Wi-Fi or onboard assistant, but it works with Google Assistant or Alexa on a paired phone.

The speaker and a USB-C charging cable. No carry strap or case is included.

Does it have a battery life figure?

Sony does not list runtime in the specs here. Owners say it lasts well at normal volume but drains fast with ULT bass boost on.

About the Sony ULT Field 1

The Sony ULT Field 1 is a small portable Bluetooth speaker with a 30 W front-firing woofer and tweeter, ULT bass boost, and an IP67 dust- and waterproof body that Sony also rates shockproof. It weighs 650 g and measures about 206 mm wide, so it fits in a bag or a bike bottle cage. It is one of the more rugged small speakers around, and owners rate its sound for the size highly. Against smaller rivals like the Sony SRS-XB100 it plays louder with more low end, but it has no Wi-Fi or built-in voice assistant and its plastic body draws some complaints.
