QUB Sound Quality
MB Quart Universal Bluetooth™ technology delivers loud, high quality music in a very small package.

High Voltage Power
QUBFour plays louder and delivers more deep bass with a built in high power amplifier that operates at higher voltage without sacrificing sound quality.

Large Drivers
Making music loud and clear requires larger speakers. QUBFour delivers an intense sound experience by using oversized drivers paired to ultra-efficient neodymium magnets.

Dual Source
QUBFour features Dual Source technology allowing two devices to be paired to one speaker. Go between tablet and phone without the need to reconnect.

Full Power
QUBFour includes a 110v adapter for quick charge of the QUB battery. Apple users can view battery status on screen.

Secure Simple Pairing
Secure Simple Pairing provides a quick and secure wireless connection between speaker and device. This reliable connection is impervious to outside interference, providing a lock-tight connection to your speaker so you can enjoy your music uninterrupted!

12 Hours of Music
Fully charged QUBFour will deliver up to 12 hours of continuous music playback.
