Cambridge Soundworks OontZ Angle 3 Bluetooth Speaker

The OontZ Angle 3 (4th Gen) is a compact, triangular portable Bluetooth speaker from Cambridge Soundworks that delivers clear 12W stereo sound, boosted bass, and up to 24 hours of battery life for home, travel, and outdoor use.

Designed and engineered by Cambridge Soundworks in the USA, the Angle 3 blends a distinctive angled silhouette with dual precision stereo drivers and a passive bass radiator to produce punchy lows and defined mids and highs. Lightweight and splashproof, this model aims to be a versatile everyday speaker for listening at home, in the shower, at small outdoor gatherings, or while traveling.

How does the Angle 3 improve sound in a small space?

The triangular chassis and driver arrangement focus audio projection while the downward-facing passive radiator adds low-frequency impact without excessive size. Together these elements deliver surprising volume and clarity for rooms, patios, and hotel rooms.

• 12 watts of amplified stereo output with a dedicated volume booster circuit
• Dual precision acoustic drivers for clear mids and highs
• Passive bass radiator positioned to enhance low-end presence
• Angled cabinet design that improves spatial sound dispersion

What battery life and connectivity can I expect on the go?

The Angle 3 provides up to 24 hours of playback on a full charge, making it suitable for day trips and long listening sessions. Bluetooth pairing is fast and stable, and the extended antenna design enables connection at distances up to 100 feet in open spaces.

• Up to 24 hours of continuous playtime on a single charge
• Bluetooth range up to 100 feet (unobstructed)
• 3.5mm AUX input for non-Bluetooth devices and TVs

Is the speaker durable enough for outdoor use and moisture?

The OontZ Angle 3 is splashproof and resists rain and light water spray, making it suitable for kitchens, poolside use, and outdoor patios. It is not designed to be submerged, so avoid full immersion and deep-water exposure.

• Splashproof construction ideal for light rain and shower use
• Protective housing that keeps controls and ports accessible
• Compact, lightweight form for easy transport (about 10 oz)
• USB charging cable included for convenient recharging

Who is this for? The OontZ Angle 3 (4th Gen) suits listeners who want big, clear sound from a pocketable speaker — commuters, travelers, cooks, and anyone who needs reliable Bluetooth audio with extended playtime. It’s especially practical for people who want a louder portable speaker with enhanced bass without carrying a bulky unit; the added AUX input and hands-free mic also make it a flexible choice for non-Bluetooth sources and calls.
