The perfect Bluetooth speaker would have great sound and a ton of features at a cheap price. The Ultimate Ears Roll comes as close as any to meeting all three criteria. It delivers full sound in a very portable, waterproof form, all for $100.

Full treble and midrange; Waterproof; Loud for an inexpensive speaker

No speakerphone; Can't control music from speaker

Available in a range of colourful finishes, the UE Roll 2 is heralded as 15% louder than the original with an extended Bluetooth range.

In a world of square or cylindrical Bluetooth speakers, Ultimate Ears' circular Roll 2 stands out, freshly updated for 2016 for music-lovers on the move. The form-factor is the same, a saucer-sized disk of tough fabric and rubber with a handy bungee cord loop on the back, it's still waterproof to...

The is fun. How do I know it's fun? Look at all the press images on the side of the box. It's gone skiing, bike riding, mountain climbing and rolling around in the mud with a bunch of attractive product models.

Overall I love my EU Roll Bluetooth Speaker. I should mention that I received the product for free to use for this review! Definitely a win for someone like me who listens to music whenever and wherever possible.

The UE Roll was one of my favorite compact Bluetooth speakers of 2015 and now there's a sequel: the UE Roll 2, which offers a couple of modest improvements over the original. For starters, it plays louder. About 15 percent louder according to UE.

The UE Roll 2 is a compact, waterproof Bluetooth speaker with a unique design, very good sound for its size, and decent battery life; It has an integrated bungee cord and an included inflatable life preserver that allows it to float in water.

It has no speakerphone capabilities

The UE Roll is a magnificent little speaker. ( Read my review about it here!) It's small, unassuming size belies the loud, impressive sound it puts out. It's sandwich roll shape shuns the boxy or cylindrical shape of most Bluetooth speakers.

Integrated bungee; Waterproof; 100-foot range; Louder than everyone; App works great; Can be turned into a stereo pair; Includes Floatie; Sounds great

Not a thing; This speaker rocks and rolls

You can only get so much power out of a small Bluetooth speaker. Ultimate Ears seems to have hit this wall with the UE Roll 2. The small, rugged follow-up to the UE Roll has longer wireless range than the original, but doesn't offer any significant audio improvements over its predecessor, and struggles with deep bass when you crank it up. But it still boasts a clever design, and sounds very good when you don't push it to maximum volume. It's a solid option at $99.99, though our Editors' Choice, the JBL Clip 2, can be found for about half as much. DesignThe Roll 2 looks and behaves identically to the original. It's a 5.3-inch disc that measures 1.6 inches at its thickest point, with front and back sides that curve toward each other to form a single circular edge. It weighs 11.6 ounces and is rated IPX7 waterproof, meaning it can handle total submersion in 3.3 feet of water for up to 30 minutes. While the Roll 2 can survive being dunked, you can't easily listen to it underwater. Fo...

The Ultimate Ears UE Roll 2 is a smartly designed waterproof speaker that offers very good sound quality as long as you don't crank the volume too high.

Waterproof; Built-in bungee cord; Crisp, clear sound
