Cambridge SoundWorks OontZ Ultra
Score: 83/100
JBL Go 3
Score: 70/100Rankings
The OontZ Ultra delivers 14 W of sound, 20-hour battery life and IPX7 waterproofing with true wireless stereo capability. Android latency and distortion at max volume are notable drawbacks. Perfect for users seeking a compact, waterproof speaker with long playtime and TWS pairing.
The JBL Go 3 is an ultra-compact speaker offering punchy bass, a built-in noise-cancelling speakerphone, and IP67 waterproof/dustproof protection. Its limited volume, short 5-hour battery and older Bluetooth 4.1 limit its use for longer or louder sessions. Ideal for travelers and casual listeners needing a pocket-sized speaker.

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. They commend its accurate frequency response and reliable 100-foot Bluetooth range, while noting the higher latency on Android devices and the absence of multi-device pairing as the main technical shortcomings.
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.
“one of the best sounding under $40... EVER!”
Choose the Go 3 if you need water resistance and louder sound; stick with the original Go for ultra-compact portability and lower cost
Professional reviewers commend the JBL Go for delivering a surprisingly full-range sound with punchy bass and clear highs despite its miniature size, highlighting its value-for-money feature set that includes a speakerphone and wired input. However, they note its limited maximum volume, short 5-hour battery, and lack of any IP rating as drawbacks compared to newer JBL mini speakers.
Everyday users appreciate the big, punchy audio and the convenience of multiple colors and a strap hook, finding the 5-hour battery adequate for casual use and the speakerphone handy for calls. Common complaints revolve around the limited loudness, faster battery drain at high volumes, no water resistance, and occasional Bluetooth connectivity hiccups.
