FAQs
Please read our FAQs page to find out more.
Which devices are compatible with the VOL20?
The VOL20 is compatible with digital audio sources that support USB or Bluetooth peripherals, including PCs, Macs, laptops, mobile phones, tablets, digital audio players, and streamers.
Can VOL20 be used with Apple TV?
VOL20 can be used with Apple TV, but the connected TV must support HDMI CEC functionality.
Can the VOL20 be used to control a DAC or amplifier?
VOL20 is primarily designed as a peripheral for audio source devices, requiring USB or Bluetooth peripheral support to function. Generally, DACs or amplifiers do not support this feature.
Why can't my computer detect the VOL20 in pairing mode?
If the VOL20’s blue light is solid instead of flashing, it's connected to another device. Delete the VOL20 from any previously paired devices, then try connecting again from your computer.
The connectivity with the Fosi VOL20 is hit or miss. I upgraded the Bluetooth with only nominal improvement. Is there a driver update that might improve the performance re connectivity?
Great addition to my desk setup. I love the weight and feel of the knob. I find myself adjusting the volume just because I want to use the VOL20. 😂 Great product and good value!
The design of the device is excellent and the quality is good. My only ask would be to release an app that allows us to reassign the functions. Instead of controlling volume, I want to be able to use the dial to FF/RW. This should be configurable.
I used this for my motorcycle so I could easily turn up and down the volume and it is perfect. I love I can change the LED color to match the Black/Red theme. The VOL20 is the only bluetooth know like this available. I tried a few different ones, USB included and none of them worked well. Well-built.
This volume knob not only saves me the trouble of fiddling with the keyboard when I need to adjust the volume on my Mac Studio, but it also looks awesome!
