Anker Soundcore 2 (AK-A3105)
Score: 77/100
Cambridge Soundworks OontZ Ultra
Score: 77/100Rankings

The Anker Soundcore 2 offers exceptional battery longevity, IPX7 durability and decent sound with BassUp enhancement, making it a solid budget choice. Its lack of modern charging, app support and microphone keep it from competing with premium models.

The OontZ Ultra offers 14 W stereo sound, IPX7 waterproofing and a 20-hour battery in a compact, USB-C-charged package. It excels in range and durability but suffers from a very long charge time and a lack of premium build materials.
