    Works great! Pair it with two other BOOM 3s for surround sound on the pontoon boat. Works great for getting enough volume to drown out the motor but quiet enough where everyone can still have a conversation.

      That's an awesome setup you've got with your Ultimate Ears BOOM 4! It's super cool to hear you're pairing it with two BOOM 3s for surround sound on your pontoon boat. We're thrilled it's delivering the perfect balance of volume to enjoy your music over the motor while still letting everyone chat comfortably. Sounds like a perfect day on the water! Logitech

    I originally bought this speaker thinking I would use it for a small outdoor gathering. Thank goodness I tried it before I wanted to use it because the sound quality was horrible. The music sounded grainy and definitely not worth $150. We had an older version of this speaker which sounded great, but unfortunately, this model was a let down.

Your feedback is important and helps us understand where improvements can be made. We truly appreciate your honesty. Logitech
