Cambridge SoundWorks OontZ Solo
Score: 70/100
JBL Go 3
Score: 70/100Rankings

The OontZ Solo is an ultra-compact speaker delivering 5 W of surprisingly loud, distortion-free sound with a 100-foot Bluetooth range and IPX5 water resistance. Its limitations include a real-world battery life far below the advertised 30 hours and the use of an older Micro-USB charging port without stereo or TWS features. It suits users who need a portable, rugged speaker for personal, on-the-go listening rather than extended high-volume or party scenarios.

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 and editors describe the OontZ Angle Solo as a compact powerhouse with a surprisingly loud, distortion-free output, a standout 100-foot Bluetooth range, and solid IPX5 water resistance, but they caution that its battery life diminishes quickly at higher volumes and it lacks advanced features like TWS or a companion app.
Everyday consumers consistently praise the speaker's portability, loudness, and ruggedness for outdoor activities, while the most common complaints revolve around shorter-than-advertised battery life and its limitation to personal-use scenarios.

“Exceptionally loud volume without distortion even at maximum output power”

“Designed for personal, mono listening; not powerful enough for large rooms or parties”



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.
