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.

Wonderfull product for wfh colleagues
Has all the things one would need, single usb connection, great quality speaker and mic, can stand on table or hang below monitor, easy buttons and bluetooth for pairing with phone simultaneously. It switches as per the signal and is totally worth it

Good
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.

Fits my monitor - smart and doesn't buzz
I've got this speaker attached to the top of my monitor where it's completely out of the way. It grips very securely and is exactly what I needed to replace the tiny buzzy speakers I had before. When not in use it's silent and the sound quality is great for video calls, occasional films and music. I don't use it at high volume, it's on my home office computer. Set up was really easy - I just plugged it in. Great price. Recommended.

Works as advertised. Good sound, volume and connectivity. Recommend
QUICK SUMMARY: -It works as expected. -Good sound quality (not excellent, it's not a Bose speaker) but good. -Works for Zoom and Music. -Easy to set up and use. -Would recommend. MORE DETAILS: I have an older monitor and the speakers on it started failing so I began using the audio on my laptop that is to the side of my monitor. It probably seems silly, but it was bothering me to have sound on one side.. my right ear started feeling funny - I don't have a better way of explaining that right now - but ultimately, I knew I needed to have the sound come from the middle of the monitor. This speaker does the job as advertised. It has a clip so you can clip it to the top or bottom of your monitor. I put mine right in the middle, bottom of my monitor. It clipped on fit fine with no issues. The part of my monitor I clipped it to is between 1-1.5 in. wide. As far as fit, I'd say this can accommodate most monitors. If you need this just for your computer, you can get by with the cheaper non-bluetooth version, as if it's just for your computer, the speaker's USB cable needs to be connected for power... for me, connecting it to power also means connecting it to the computer therefore the bluetooth is not needed unless I decide to connect my phone to it, which is unlikely. I connected the USB and it popped up as an option for audio right away. I haven't had to use through bluetooth but I did connect and it worked fine. You can also use this as a mic. I don't use it because my webcam has a mic, but if needed, you can use this for that. The sound is clear and works great. The volume controls are great, you have a good range of volume. I appreciate that as sometimes I need some music/sound without being too loud to distract me and had previously struggled with the volume controls of the monitor that didn't allow a wide-range. I use it for work meetings through zoom and have had no issues, just changed my speaker option in the zoom app - keep that in mind. Sometimes with Zoom, selecting the speaker for the computer itself is not enough, you have to go to mic, the arrow on the side, and select which speaker you want to use. I've noticed that Zoom trumps this setting over the computer. Overall, this is a good choice and for the price, a solid buy. Would recommend.
