Sonos has just released an updated version of the California brand’s smallest and most portable speaker. Sonos Roam 2 comes with improved acoustics, battery, and Bluetooth capabilities right out of the box. Among the main features of Roam 2 are:

• Sound that does not match its size: It delivers the same rich, detailed sound and bass with the clarity, depth and fullness you’d expect from a larger speaker.

• Updated design and user interface: It includes a stylish monochrome logo and separate, independent power and Bluetooth buttons for ease of use.

• Instant setup: Just take it out of the box and it’s ready to connect to your mobile device via Bluetooth to instantly enjoy your music. And when you get home, it can be set up using Wi-Fi to connect to the rest of your Sonos system.

• Automatic Trueplay mode: Calibrate sound to suit your environment and enjoy the best listening experience anywhere, accessible via both Bluetooth and Wi-Fi.

• Power for adventure: The Roam 2’s battery provides up to 10 hours of continuous playback on a single charge.

• Prepared for the elements: Dustproof and fully waterproof with a strictly certified IP67 rating, so it can easily withstand splashes, dirt, heat and cold.

• Five vibrant colors: Available in olive, sunset, wave, black and white to suit any style.

Roam 2 is now available worldwide for the equivalent of US$179.
