Cube

A 3.5 in speaker for the kitchen, the balcony and the park. Cube puts a 20 W full-range driver and a passive radiator inside a fabric wrap, with one lime button on top. It is rated IP67: sealed against dust, and fine after half an hour in about 3 ft of water.

In our test room it reached 88 dB at 3 ft, enough to fill a living room without distortion. At half volume the battery lasted 15 hr 40 min, close to the 16 hr rating; at full volume, plan on about half that. Bass from a box this size is tighter than it is deep, and it sounds fuller with a wall or a corner behind it.

Out and about

• Up to 16 hr per charge, 3 hr back to full over USB-C
• 1.2 lb, small enough for a tote bag or a bike basket
• Sand, rain and a drop in the pool: IP67 covers all three

Two for stereo

• Pair two Cubes over Bluetooth 5.3 and they play left and right channels
• Set them 6 to 10 ft apart for a stereo image that holds across a room
• Your phone connects to one; the second follows it

Care

After salt water or a sandy beach, rinse Cube under the tap and let it dry before charging. Cell 20 keeps it playing through a weekend away, and Brick 65 charges it at home. Covered by our 2-year warranty.
