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.

Great Sound for Price and Size
Very happy! Would definitely recommend. I bought the blue tooth model. Been using it for 3 days, so far here are the pros and cons. Ultimately I would recommend this sound bar for general computer sound needs - would not recommend for hardcore gamers or as a sound system for music - don't think its marketed as such anyways. Pros: 1. Compact 2. Easy to carry and pack 3. One cable connection, usb for power and sound 4. With cable connected, no lag issues 5. Very good sound quality and range for office computer, voice/vocals are load and clear, music is good - not great but definitely good 6. Controls are easy, and work well, mute, bluetooth, volume up and down 7. If can't clip onto monitor, monitor clips works as good stand 8. Microphone is good. 9. Volume is great for the size and cost. Max volume is loud and there is very little distortion/noise. Cons: 1. Does not clip on to my monitor - not on the top or bottom. Bottom, the clip is not big enough. Top, clip goes on, but spring force is to strong causing it to slip off. I just place it on my desk, its compact so you don't need much room. 2. Bass is okay, but you wouldn't be buying a soundbar at this price and size for deep bass. Mid to high frequency is good.

Good Sound at an Affordable Price Point
I'm pleasantly surprised with this speaker. The last one I got was of another style and type and a poor performer. This one is clearly better right out of the box. My monitor turned is huge and out to be too thick to mount on with this clamp. However, I have a book shelf right above the monitor and was able to easily clip right on at arm's-length.

Good for the price, QOL some issues though.
For my Switch, I use a monitor that doesn't have a speaker, and so I bought this just for my Switch. I connect via USB, but got the BT version of this speaker since it was only 5 bucks more to have the expanded utility should I ever want it. It's easy to set up, stays put when clamped to the monitor, and the sound quality is quite good for a 30 dollar USB/Bluetooth speaker. However, I have two major gripes: 1. The LED lights are large (compared to what I see on similar electronics), bright, and can't be turned off without disconnecting the speaker. I use a product called light dims blackout edition (you can buy them on Amazon for cheap, they're very useful beyond this product!) to block this LED so it's not an actual issue for me, but it's notable as an issue that you can't dim or disable the LED. 2. There is a voice alert that says, I believe, "PC connected." when it senses it has received a connection. I have never paired anything to it with Bluetooth, only USB. I can *maybe* understand this voice alert for wireless connection, but it's pointless with a wired connection, I know when it's connected, I plugged it in! This is an issue because, for some reason, this will occasionally sound "PC connected" when my Switch is in sleep mode. I suspect perhaps this has something to do with the Switch semi-waking to check for system/software updates or something, but it was quite the surprise when it sounded out in the middle of the night! I checked the (ahaha right as I'm typing this, with my Switch sleeping, it said it!) paperwork that came with the speaker and can find no way to turn this alert off. It happens a few times a day. This will likely cause me to return it, since I don't want it randomly making noise in my bedroom.

Buy it!
I love this speaker. I will clip on my monitor, however my monitor must be a bit wider cuz with the slightest touch it falls. I have no complaints. The volume is great and it was easy to install.

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.

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.
