Cambridge Soundworks OontZ Angle 3 Ultra Bluetooth Speaker

The OontZ Angle 3 Ultra is a compact, 14-watt portable Bluetooth speaker that delivers boosted bass, clear stereo sound, and IPX7 waterproofing for up to 20 hours of playback.

Designed for people who want louder, fuller audio from a pocket-sized speaker, the OontZ Angle 3 Ultra combines dual precision drivers, a dedicated bass radiator and a tuned digital audio processor to produce rich sound that travels. With Bluetooth 5.4, a claimed 100-foot wireless range and the ability to wirelessly pair two units for true left/right stereo separation, this model suits home use, outdoor gatherings, travel and poolside listening.

How does the OontZ Angle 3 Ultra improve bass and overall clarity?

The speaker uses a digital audio processor to boost low frequencies while keeping mids and highs clear. Dual precision stereo drivers handle detailed tones and the proprietary bass radiator adds punch without muddying the mix, even at high volume.

• 14 watts of combined power for room-filling sound
• Dedicated bass radiator for deeper lows
• Digital audio processing for clearer mids and highs
• Distortion-free output at maximum volume

What connectivity and range can I expect for Bluetooth playback?

The Angle 3 Ultra uses Bluetooth 5.4 and an advanced antenna design to maintain a stable connection up to 100 unobstructed feet from your device. Pairing is quick and works with smartphones, tablets, laptops and compatible Echo devices.

• Bluetooth 5.4 for fast, stable connections
• Up to 100 feet of unobstructed wireless range
• Simple one-step pairing routine

Can I use more than one speaker for improved stereo sound?

Yes — two OontZ Angle 3 Ultra speakers can be linked wirelessly so one plays left and the other plays right, creating wider stereo separation and a more immersive listening field. Place the speakers up to 100 feet apart to tailor the soundstage to your space.

• Wireless two-speaker stereo pairing supported
• Left/right channel assignment for proper stereo imaging
• Speakers remain independently portable when not paired
• 3.5mm cable lets one speaker accept audio from non-Bluetooth devices

Is the OontZ Angle 3 Ultra durable and good for outdoor use?

Built with IPX7 waterproofing, the speaker can be submerged up to 1 meter for 30 minutes, making it suitable for beach, pool and outdoor use. Its lightweight, portable design and long battery life make it easy to bring along on day trips and gatherings.

• IPX7 rating — submersible up to 1 meter for 30 minutes
• Ultra-portable, lightweight housing for travel
• Up to 20 hours of playtime on a single charge
• Includes USB-C charging cable (carry case sold separately)

Who is this for: The Cambridge Soundworks OontZ Angle 3 Ultra is aimed at anyone who wants a small, affordable speaker that punches above its weight—music lovers who need stronger bass and clearer highs than typical pocket speakers, beachgoers and poolside listeners who need IPX7 protection, and casual audiophiles who want the option to pair two units for real stereo separation. It’s a smart choice for commuters, students, small parties, and outdoor adventurers who value portability, reliable Bluetooth range and extended battery life without sacrificing sound quality.
