Good when wired, unuseable on BT && works on Linux :)
Reallyzen 14.09.2022
A USB DI is infinitely superior to using the crap minijack output of your laptop for performances, and here the Sirus USB-DI does it for you, no more mess of whatever adapters before going into a DI box anyway - also, I use arch btw and it works straightforwardly.

Did I say "no more mess"? Wait, that device won't work on a usb-c to usb-c cable, you HAVE to plug an adapter from C to A then use a regular A to C cable to use it (forget it on modern hardware)

But, why bother with wires, there's Bluetooth right? Here it falls completely, utterly on its face is with the quality of the sound on the BT interface; it is just unusable, even as background music. I couldn't quite believe my ears so I switched around 2 laptops and my cellphone, each time comparing Wired vs. BT. I have other BT devices around, and was able to check that my BT output was clean, the sound rendered on the Sirus output was awful, mushy, flat while absolutely OK when wired.

One way of testing this was to use a little JBL speaker that features both a minijack input, (wired from the Sirus headphone output), and a BT input ; connecting my phone to the Sirus BT provided very poor sound quality while connecting my phone straight to the JBL provided good sound. With the laptops it was just a matter of switching around between Wired/BT and it's the same, unfortunately.

Buy it for the DI, do it, but forget the BT. And usb-c.

Satisfying product but defective USB-C
Léo 30.01.2024
Overall quite satisfied with this product after 4 years.

The only problem is that the manufacturer decided not to include two mandatory pull-down resistors in the USB-C connector, violating the USB-C specification and making it impossible to use this product with a standard USB-C-to-C cable. As a consequence the product can only be used with a USB-C-to-A cable.

Features: 5/5, Bluetooth works well and is very practical.
Sound: 4/5, perfect sound with USB but slightly quieter with Bluetooth.
Quality: 3/5, solid build but defective USB-C connector.

Final rating: 4/5.

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.

Very stable, with good range.
Phil Boorman 09.11.2022
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.
