Is the Ultimate Ears WONDERBOOM 4 worth buying?

Yes, for most people. It is the right buy if you want a small, cheap speaker that floats in the pool and clips to a backpack. We score it 8.2 out of 10.

A fair price to pay

$69–$99

Usual price range in the US. At or below $69 is a good deal. Paying more than the top of the range? Check another store, or wait for a sale.

Our higher-rated pick

JBL Flip 7

Usually $119–$149. Pick it if you want a tough, waterproof speaker that sounds big for its size and fits in a backpack bottle pocket.

Before you check out

  • Buy from the store itself or the brand’s official shop, so the manufacturer warranty applies.
