Good value for the money
Barley-Popper✓ Verified Purchase•November 6, 2023
My monitor has such a thin bezel that it ends up clipping onto the screen rather than the bezel so I ended up just setting it on the desktop and that works fine. The green LED is way too bright. For best performance the speaker obviously needs to be pointed straight at me and it always feels like that led is trying to burn a hole in my retina. It needs to go on top or in the back. Actually since this thing doesn't have an on/off switch I don't esee the point of having that LED in the first place. The sound quality is decent, I didn't expect exceptional at this price point. I would buy it again.
Great Quality

It sounds great, controls with the OS sound so turning down on the speaker turns system sound down, and being a 1 wire speaker with a clamp makes it easier to take around for my laptop.
The clamp sits well in any direction you put it on and sounds great even if its on a side vs the top middle.

Works well, but is a bit heavy for a laptop screen

I blew out my laptop speakers watching the expanse in a hotel, with sound up to 100 so I could hear everything over the A/C, horrible buzzing on the laptop speakers made me want to find a small portable speaker I could hook up.
I didn't fully read the size specs of this and it looked like it fit the bill and bonus is I didn't have to pay for a battery. It seemed small enough based on the video reviews and pictures, but in person it's bigger than I would have liked.
Sound is about 100 times better than (fully functional) laptop speakers, which is no surprise. Minimal base output which is also no surprise, but it is definitely better than built in laptop speakers. The 4 star sound quality rating I provided based on "Quality relative to size and price", not in absolute terms.
While it does stay on the laptop screen, it is heavy enough to give the hinge a bit of an issue. It holds, but the extra mass at the top of the screen results in more screen wobble while typing than when the screen is unencumbered. It works, but I wouldn't want to leave it here for long typing sessions. So using it for movies, etc with minimal typing is about the only use I'll give it.
The clamp does affix it to my laptop screen, the angle of the clamp forces the speaker to lean forward a bit, and its "secure enough" but not such that it is not at risk of falling off if you move the laptop around halfway energetically moving from one seat to another. On my 15" HP pavilion it does obscure about 1/4" vertically of the top of the screen. Its a minor annoyance. However, they did design the clamp such that it provides a nicely stable stand for it to rest on a flat surface when not clamped. That was a nice surprise and lets you use it as a plugged-in bluetooth speaker for anything you care to pair it with.
Chord length is about 5 feet, so you shouldn't have too many issues being able to plug it into a "charger" and sitting it on a table or window sill for that secondary use. Currently I as use it for the laptop I don't have it sitting on the screen, just on the coffee table (or table) behind the screen so I don't add any wear and tear to the laptop hinge.
Overall, a nice product. I just wish there was something available about half its size. I know it wouldn't sound as good as this, but a smaller item would have suited my particular need better.

I use it in the courtroom as a court reporter

I attach this to my laptop in the courtroom while working as a court reporter. Whenever I need to play back my audio, this does an excellent job! I even had a judge comment that he needed one of these for his laptop! The audio quality is nice, clear, and loud. It's very, very portable and lightweight. Definitely love this item! Thank you!!
Great Sound for Price and Size
Matts✓ Verified Purchase•August 13, 2023
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.
