## At a glance

- Manufacturer claims up to 18 hours of playback at under 50% volume and a full USB-C charge in approximately 2.5 hours.
- Bluetooth 6.0, NFC Fast Pair and dual-device connection are listed. USB-C audio is claimed to have less than 60 ms latency.
- Pair two Speaker S units for left and right stereo playback. Auracast Party Mode is described for compatible speakers.
- The listing claims IP68 dust and water resistance, including submersion up to 1.5m for up to 30 minutes.
- Sound options include four stated presets and a custom EQ through the Nothing X app.

## Pros

- Compact listed dimensions and 334-gram weight make it easier to carry than a larger speaker.
- USB-C audio offers a wired option for desktop films and gaming, while Bluetooth and NFC support wireless pairing.
- Physical controls include a playback knob and dedicated power, Bluetooth pairing and Auracast buttons.

## Cons

- The claimed 10W output and small 45mm driver indicate a compact-speaker format rather than a high-output party system.
- The stated 18-hour playback is conditional on listening below 50% volume, so louder use may not match that figure.
