What happened

Nothing kills the vibe of a beach day faster than forgetting the music, which is why shoppers are snapping up this portable speaker while it’s 30% off ahead of Prime Day (June 23 through June 26).

Why it matters

The Ultimate Ears WONDERBOOM 4 was practically made for sand and surf.

Common ground

It’s IP67-rated, waterproof, dustproof and floatable, so nothing gets between you, a good playlist and a sunny summer day.
