★★★★★

Good sound quality

Eggo—December 8, 2025

Not as much bass as I would like but it still sounds really good and really clear. The range is also one of the reasons I bought this. You ca walk away from it pretty far and it doesn’t loose connection with your phone. Read more

Must buy

Rufino Diaz—December 23, 2025

Best speaker I own. I love the battery life on this thing. Read more

★★★☆☆

Overpriced beyond all recognition.

Candyflipper—December 22, 2025

For 730$ you can get a jbl partybox 520. I would love to see a comparison video between the turtlebox and the pb520. The JBL would wipe the floor with the turtlebox. Also, the 126 db rating is a complete lie. Try more like 105 db and at that volume the driver distorts terribly. Read more

★★★★★

Loudness and the way sound carries

ROBERT W DONNER—November 24, 2025

Exceptional sound. Sound travels further than any other outside speaker we’ve used on a job site. Read more
