OontZ Angle 3 Bluetooth Speaker Review

Having personally used the OontZ Angle 3, it’s easy to see why this speaker is so popular. Despite its small footprint, the sound quality is crisp and surprisingly loud. The bass response is balanced, and vocals remain clear even at higher volumes. I’ve tested it in multiple settings—whether in my shower, during picnics, or while working in my home office—and it has consistently impressed me.

One of the most standout features is its incredible battery life. A full day of playback without recharging is a huge advantage, especially for travel and outdoor use. The 100ft Bluetooth range is another game-changer, letting me control the speaker from across my backyard without signal drops. Its IPX5 rating makes it stress-free to use near water, and its compact size ensures it never feels like a burden to carry.

I personally own four OontZ Angle 3 speakers—one for my car, one for my bathroom, and two that float around the house and outdoor trips. For the price, it’s almost impossible to find another portable speaker that matches this performance and reliability.
