    • Good speaker, great price.
Style: USB-No Mic
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 is a Great computer speaker!!
Style: USB-No Mic
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!!! ... show more

    • Works well mostly.
Style: USB-No Mic
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. ... show more

    • Great volume! Great speaker!
Style: USB-No Mic
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!! ... show more

    • It works - that's it.
Style: USB-No Mic
It's nice and compact, and you just plug it into any USB port and it works. ... But you have to accept that you're not getting the greatest speaker ever at this price point. The sound quality is a small step down from my old speakers (bought them in 2006 I think). And the volume control is very imprecise; it moves it in pretty large increments, so you may find that the first setting above mute is actually too loud for you. You'll have to do the fine-tuning on the computer. I went with this one because I'm operating under a big constraint in desk space and money, so this was the best option. It works if you just want to listen to music, but audiophiles will probably want to look elsewhere. ... show more

    • Incredible value, highly recommend.
Style: USB-No Mic
The media could not be loaded. 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! ... show more
