On a full charge, at full (or nearly full) volume, the Megaboom made it through most of the trip, having to hand duties over to its smaller brother in the tail end. I did put them to the test during an 11-hour road trip from Metro Detroit to upstate New York in which I used the speakers as my primary audio source.

My experience saw results a hair under those numbers, but they still lasted long enough to fit my use. You can also rest easy thanks to each speaker having healthy battery estimates, 20 hours for the Megaboom, 15 for Boom 2 and 9 for Roll. The UE Roll even comes with a floaty, essentially begging users to bring it on their next trip to the pool. In order for the speakers to be waterproof, there are hefty flaps covering any plugs that can be quite cumbersome but the tradeoff is worth it. I was not brave enough to test that myself, but the knowledge did make me less nervous to have them anywhere I went. It helps that all three are waterproof, with claims they can be immersed in water for up to 30 minutes. Not elegant like Sonos’ line of wireless speakers, but with what Ultimate Ears has built you won’t fear bringing them on a camping trip, a day to the beach or pool party. Fingerprints are prone to show up on the devices, particularly in darker colors like the black and grey combination our Megaboom came in.

All three are made out of a rugged rubber material that makes them feel solid and durable. Ultimate Ears’ larger speakers, the UE Boom 2 and UE Megaboom have a distinct cylindrical design, whereas the less expensive UE Roll looks like something closer to a UFO.
