TechRadar described the UE ROLL's greatest flaw being "that it replaces the Mini Boom".Amazon ue bluetooth speakers : Ue Bluetooth Speaker While generally well received as a rugged, weather-proof speaker, the UE ROLL has been criticised for a lack of deep bass. Charging is done using a provided micro-usb to usb cable, and is estimated to take 5.5 hours for a full charge. Ī rechargeable lithium-ion battery is built into the UE ROLL, providing up to 9 hours of playback. 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). In addition to supporting Bluetooth, the speaker can be connected via a standard 3.5mm audio input.
In terms of sound output, it supports a maximum of 85 dBA in a range of 108 Hz–20 kHz. UE ROLL consists of a 51-millimetre (2 in) driver coupled with two 19-millimetre ( 3⁄ 4 in) tweeters which are in stereo, so there is a small amount of stereo separation. 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.
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. 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. It is coated in a water-, dirt-, and stain-proof material and partly covered with rubber. The speaker is of a discus-like shape, 13.5 cm (5.3 in) in diameter, 4.4 cm (1.7 in) maximum thickness, and weighing 330 grams (12 ounces). The UE ROLL is an ultra-portable speaker manufactured by Ultimate Ears, supporting Bluetooth and wired connections.Īnnounced on June 16, 2015, the UE Roll replaces Ultimate Ears's UE MINI BOOM as the company's lower-end model.
