Professional reviewers rate the OontZ Angle 3 Ultra highly for its portability, robust IPX7 waterproofing, long battery life, and surprisingly powerful 14 W sound output.

Everyday users consistently praise the speaker's loud, bass-rich audio, long battery life, and waterproof durability, describing it as an excellent value for outdoor and casual indoor listening. Recurring complaints focus on distortion at max volume, occasional Bluetooth dropouts beyond 30 ft, and limited controls on the secondary TWS unit.

“the perfect portable Bluetooth speaker”
Professional reviewers and editors consistently praise the Boom 2 for its massive 80W output, deep BassUp-enhanced bass, long 24-hour battery life, and rugged IPX7 floatable construction, while also highlighting the PartyCast 2.0 multi-speaker sync and customizable app features. The main criticisms focus on its relatively heavy 3.66 lb chassis and the tendency for bass to dominate the mids at full volume.
Everyday users echo the professional praise, emphasizing the speaker's portability, strong bass, long playtime, and useful power-bank function for outdoor activities. Common positive remarks center on the easy carry strap, intuitive controls, and suitability for beach or camping parties, while the few negative comments mention the weight and occasional bass-overpowering effect.
