[3] Ultimate Ear's claims that the speaker is IPX7-rated waterproof, meaning that it can be fully submerged in water up to 1 m (3 ft 3 in) depth for up to 30 minutes.
[3] The speaker comes in several colour schemes, and includes a "snap & go" bungee cord loop attached to the back of the device, which can be detached on one end.
It is suggested that this allows the speaker to be hung up, or attached to, fixtures, as well as clothing, shower heads, bicycles, or even a person's hand.
It also supports Bluetooth 4.0, allowing it to be remotely switched on by a connected mobile device running Ultimate Ear's app, and giving the speaker a wireless range of up to 20-metre (66 ft).
[3] While generally well received as a rugged, weather-proof speaker, the UE ROLL has been criticised for a lack of deep bass.
