Sirus DI USB/BT

Great product, really good build quality and good sound quality. When using Bluetooth it can sometimes boost low frequency but for testing equipment and listening to music while working it's really good.

These units are a must when running stages for acts that use backing music. It is much more practical, reliable, and offers better quality audio than running cables from a headphone jack from a phone, tablet or laptop etc.
The units have a very impressive range, and very good battery life from a single charge.

Massive box, firm knobs, stiff controllers, several features - mono stereo, ground knob, usb & BT mixer, rechargeable battery etc - flawless connectivity, perfect sound... I bought it a year ago, use it constantly....All this at this price?! Could certainly cost double+ ! CPERFECT!
