Works great. Sound quality is nice. It hangs right under the monitor and is conveniently away from the rest of the needed desk space. It is super affordable and is definitely a more bang for your buck type of purchase. It is light weight, easy to install, and easy to adjust as needed.

This speaker is exactly as shown!! I love it! It fits so nicely right under my desktop screen. The sound is also incredibly loud and clear. It was also so very easy to set up and connect all by myself. It lights up as soon as the computer is on and stays on until the computer is turned off. As far as I'm concerned the price was extremely reasonable compared to other higher priced speakers. Definitely worth the money for all of the above reasons!!!

This is a nice little speaker. I like the small form factor, a clip with a very strong sprain that helps it hold the cup of a monitor or similar. I also like that it USB power. I appreciate the new buttons, and they play post buttons as well as the indicator lights on top of the unit. The speaker also did not require any type of drivers. I plugged it into my Windows 11 computer and it was immediately recognized USB audio device. My only complaint, and I don’t know whether it’s due to the speaker or not, is that the microphone function doesn’t work. Even though I can see the speaker listed as an option for audio input as a microphone, it simply will not work. Which is a disappointment. Yes that is the reason why I am only giving it four stars. Other than that, it’s a very small, useful speaker, and as long as you keep your expectations at an appropriate level, I think it is very decent as far as sound quality goes for things like watching YouTube videos or casual gaming. I also think it’s really good value for the money.

Iv been using for over a year. Being remote since 2020, I acquired my own curved flat screen and other equipment to assure it was under My control. Obviously speaker won't clip to a flat screen, But it works perfectly attached to flexible phone arm that connects to back of desk. ( one of the arms to take your own pictures w/cell ph) Perfect , connected to Teams by Blue tooth. Loud crisp sound. 👌

Great volume! My all-in-one computer of over 5 years had a front speaker with loud volume. When that computer went down and I had to get a new one, the volume of the new computer's speakers is much lower. I do have a high-pitched hearing loss, but the other computer's volume was perfect. So I needed an external speaker for the new computer to increase its volume. Wondered how this one would work, but it's great! Attached easily to the top of the screen, and the volume is truly great. Most of the time, I don't even have to turn it all the way up for it to be loud enough. Fabulous speaker! The only thing I would change is for the USB C adapter to actually be attached to the power cord. It comes a tiny packet inside the larger box that the speaker comes in. The adaptor is small, and could be easily lost or overlooked. The power cord of some similar items have both USB A and USB C options attached. But, this speaker comes with USB A on the power cord ~ and a USB C adapter included in the packaging. Speaker is still great quality! Have used it for a couple of months now, and hope it'll last well! Couldn't use my new computer without this speaker! Used a different all-in-one computer today, and while its volume was much louder than my computer ~ even with this speaker ~ the sound quality is so much clearer and better with this speaker! The other computer's sound was terrible compared to this speaker's crystal clear sound! Impressed, and grateful to have this speaker! Thanks so much for carrying, Amazon!!

This little speaker plugged into my computer's USB-A port (it comes with a USB-C adapter) and immediately began working. I didn't even need to read the manual. It clipped on my monitor and boom, done, working. The sound is perfect for my needs - surfing the web, watching videos, etc. But if you plan to use this to listen to music while you work, I would advise you buy a different speaker that has bass response. This speaker has zero bass. Zero. Again, it's great for my needs and for the price. I am very happy with it. I don't need bass, and I appreciate how well designed it is and how easy to use it is.

I wasn’t sure what to expect with these soundbars, especially given the price. However, I am very pleasantly surprised! I ordered a pair of these for both myself and my fiancée and I couldn’t be happier with the purchase. They are incredibly easy to install. You literally just take them out of the box, clip them to your monitor, and plug them in! I will say, it is pretty snug on my monitor, which is a little thicker on the bottom. My fiancée has an average gaming monitor, and it fit perfectly on hers. As soon as I plugged the soundbars in, both computers recognized them immediately. Each soundbar came with a USB-A to USB-C converter. Neither of us needed it, but it could be nice if we upgrade in the future. The sound quality is really good as far as we can tell so far. For this price, these speakers really do pack a punch. Even at max volume, there isn’t a perceivable drop in audio quality. I see some reviews mention a lack of bass, but it hasn’t been that noticeable. Depending on what you’re watching/listening to/playing, it may be more noticeable to you. The soundbar also has four buttons on the bottom. Two to adjust volume alongside play/pause and mute buttons. This isn’t the biggest deal for me, but my fiancée has a tenkey-less keyboard that lacks the function of volume adjustment. This saves her from having to tab out of what she’s doing just to turn her volume up or down. Overall, these soundbars are an absolute gem. We got ours on sale, which made the deal even sweeter. These will be perfect for long sessions at the computer where we don’t want to continue wearing headphones or during times where we might want to play music/videos together. I could not recommend these enough! If you’re even thinking about it, just buy it. It’s worth well more than what you pay!

I am specifically reviewing the non bluetooth version of these. They are great simple speakers. I have gone through a few different more expensive speakers for people that have been just horrible for people with laptops and docks. The other speakers turn off if the laptop is not docked. Require reconnecting to bluetooth if they take their laptop back to the office and need to use the speakers. These just plug in and work. No power button, no bluetooth. And because USB A ports are almost always used up on the docks, having the USB A to C adapter is a godsend. Sound is perfectly fine for office computer speakers. The only issue i have is that the clamp is not wide enough for some monitors. Two stations, 1 has curved samsung monitors and they will not clip to the bottom. Another station has the same size and curved monitors but different brand, and they clip on and look great. If the clip was just a little larger I would give them 5 stars.
