Purpose-built portable audio

The Ultimate Ears Everboom is a wireless Bluetooth speaker designed for outdoor use. Its IP67 rating makes it dustproof, waterproof and able to float for up to 30 minutes at a depth of 3.3 feet. The cobalt blue enclosure uses at least 58% post-consumer recycled plastic by weight.

Build integration and freedom

Pair the speaker with a smartphone, tablet or any device supporting the A2DP profile for audio playback. Two source devices can connect simultaneously, and the wireless range reaches up to 180 feet. A USB-C cable is included for recharging the lithium-ion battery, while a carabiner lets you clip the unit to a bag or loop.

Sustained-output behaviour

The battery delivers up to 20 hours of playback between charges. Two active full-range transducers measuring 56.6 by 56.2 mm work with two passive radiators of 49.4 by 87 mm to produce a maximum SPL of 90 dBC in normal mode and 91 dBC with Outdoor Boost engaged. The speaker can also be linked with other compatible Ultimate Ears models for expanded coverage.

Questions about this item

How long can the battery last at maximum volume before it needs recharging?

Does the speaker become hot or make fan noise during extended outdoor use?

The EVERBOOM has no internal fan and relies on passive cooling; the IP67-rated enclosure stays cool to the touch even after hours of continuous play.

Any smartphone or tablet supporting Bluetooth A2DP works; the speaker pairs wirelessly up to 55 metres away and can remember two devices simultaneously.
