Ready for the pool

The Ultimate Ears BOOM 4 is a portable Bluetooth speaker built for outdoor use. Its IPX7 rating means it can be submerged in up to 3.3 feet of water for 30 minutes and it floats. The Raspberry Red model delivers 360-degree sound with deep bass, weighing 620 g and measuring 184 mm by 73 mm.

Fits in a bag, pairs with a phone

The speaker connects wirelessly to smartphones and tablets using Bluetooth with a 45 meter range. A rechargeable lithium-ion battery provides up to 15 hours of play time at default volume. It charges via USB and includes an attached bungee for hanging. The Ultimate Ears app adds PartyUp for linking compatible speakers and one-touch playlist control for supported streaming services.

Holds output for the full session

At 30% volume the battery lasts the rated 15 hours before needing a recharge. The enclosure is drop-proof up to 1.5 meters, so physical shocks do not interrupt playback. Plastic parts contain a minimum of 52% post-consumer recycled content by weight. Maximum sound level reaches 85 dBC, maintaining balanced audio until the battery depletes.
