Cambridge Soundworks OontZ Ultra
Score: 77/100
EWA A106 Pro
Score: 61/100Rankings
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.
The EWA A106 Pro is a palm-sized, IP67-rated Bluetooth speaker with strong bass for its size, lightweight design and a travel case. It offers up to 12 h playback at moderate volume but lacks a microphone, aux input and can be quiet at high volume.
