Cambridge Soundworks OontZ Angle 3
Score: 73/100Rankings

The OontZ Angle 3 delivers loud, clear audio with a marathon-long 30-hour battery in a compact, IPX5-rated package. It supports stereo pairing but lacks an aux input and uses an older Micro-USB charger.

The OontZ Angle 3 Ultra delivers long playtime, robust waterproofing and solid sound, with the added benefit of dual-pairing for stereo, though it lacks an app and has an always-on LED.
