Review: Good VFM speaker for PC - Sound quality is superb. I got this because the speaker assembly of my aio pc broke down after service center guys opened it. It's a USB plug and play. No need to pair via BT. If your aio has a thick bezel then this may not be useful at the bottom. The size is appropriate - not too big nor too small. The performance is adequate - it's doing the job it was bought for. Insanely good value for money product. Would highly recommend this.
Review: Good speaker - Nice speaker go for it ,it's compact size makes it a exceptional speaker

### ⭐⭐⭐⭐ Good
*by S***U on 9 October 2023*

Good & Clear sound. Loud enough for personal use. Has been looking for a similar speaker (which can be clamped to laptop) since the Philips one went off market. Only a single cable is a big plus. However, considering that it costs almost thrice as the Philips one, let's see how long it lasts. It is simple plug and play, both on Windows and Linux. However the volume in digital mode is noticeably low than analogue mode.
