FAQs
Please read our FAQs page to find out more.
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.
Connected very easily. Lights look good. Controls volume of TV very easily. Knob has no ends, so you will feel to keep moving it or playing with it once you are not using for increasing or decreasing the volume. I Ioved ❤️ the Vol20.

I love this. I no longer need to have a volume knob on my keyboards - I can control the volume anywhere with the VOL20. The build quality is excellent, and it feels solid and heavy. Very easy to connect to PC. I highly recommend to get one.

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!

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.

Excellent knob, installed it at my home workstation. Thank you

The knob has a nice feel and weight to it. I actually don't mind the wobble. I would rate this 5 stars but the bluetooth connection is terrible. It constantly disconnects and reconnects. It's sitting 6 inches from my mini pc so it's not a range issue. I have tried it on 3 different pc's and they all exhibit the same behavior. Also windows has no idea what the battery percentage is at, it just seems to give a random number. Hopefully they come out with a gen 2 with either better bluetooth or a 2.4ghz dongle. I would buy it in a heartbeat.
Funky looking device that connects esily and works well. Also has good battery life and easy to recharge. The turning knob doesn't have a crisp volume control fell and has a floaty/wobblely feel, not firm like an amp volume control. 3/5

Knob works great, but the other comments about the "play" in the dial is very true. There's about 3mm of wobble in the dial which is very noticeable, and while it doesn't impact function, it degrades the feeling compared to a smooth and solid bearing.
The weight is pleasing, and BT connectivity works as it's supposed to.
Battery life is great - 25+ days with the "light when used" setting, and charges quickly.

Let me start by saying that I love this volume control. Fit and finish is excellent however, windows constantly reports a low battery state even on a full charge and it is extremely annoying. I swapped the unit out through Amazon because the first one was doing this as well. Hard to believe this would be user error or a case of RTFM.

I use this as my volume control when listening to music. It's much easier to use than the controls on the laptop, tablet, or phone I normally use. Not only is it handy to use, It also allows for very fine control. No more accidental spikes in volume due to over adjusting. One improvement I would suggest is to make the ability to skip forward easier to use.

The Fosi Audio VOL20 is a fantastic little Bluetooth volume knob that brings tactile control and smooth wireless audio to any setup. Easy to pair, responsive, and feels solid in hand, it makes adjusting volume way more intuitive than tapping a screen. Great sound quality and dependable performance — a simple upgrade that just works.

看了其它买家的评论，很客观，蓝牙4.2频繁锻炼，受干扰的因素很多，在电脑端的音量显示也不准确，希望能升级固件，推出软件自己可以设置旋钮的功能，阻尼感一般，段落感不强，希望第二版能有棘轮，手感和声音体验会更好，另外希望通过合计改进晃动的问题。
Works well, though the bluetooth lag takes some getting used to. Also, I find the pause/ff/rew button to be mounted too low, it’s hard to make good thumb contact when it’s laying flat on the desk.
