Review: Perfect! - My laptop audio was way too quiet even on full volume. With this speaker I now get much better audio, the tone is richer and deeper (and louder!). I clipped it to the top of my laptop screen and it’s perfect. Very happy with it
Review: complete absence of any real bass sound - Nice design its very small it 'clamps' itself onto bottom bezel of monitor surprisingly well it will never fall off, looks great the speaker bar quality is about right for its high price, the controls are easy to find and use. however, while it may go surprisingly loud for its small size, it's also a thin tinny sound absent of any bass whatsoever, which is hardly surprising considering its small compact size. If a complete absence of any real bass in the sound is not important? then its a great little sound bar likely last years

### ⭐⭐⭐⭐ complete absence of any real bass sound
*by M***N on 11 March 2023*

Nice design its very small it 'clamps' itself onto bottom bezel of monitor surprisingly well it will never fall off, looks great the speaker bar quality is about right for its high price, the controls are easy to find and use. however, while it may go surprisingly loud for its small size, it's also a thin tinny sound absent of any bass whatsoever, which is hardly surprising considering its small compact size.

### ⭐⭐⭐⭐⭐ Good clip on speaker for my laptop
*by D***N on 26 November 2022*

I was getting fed up of the frankly rubbish sound quality from my (otherwise good) laptop speakers, so after searching online settled on these to solve the problem. And they do, not massively loud, but a big improvement on laptop speakers for music, video and teleconferencing. The clip is a convenient shape that avoids blocking the camera, and the sound quality is pretty good. I like the option to plug into USB or USB-C (I mostly use the latter as it doesn't get used for much else), and not requiring power or more than just the one plug. The buttons on it are interchangeable with screen/keyboard controls for volume and muting. A good honest sensibly priced product, that isn't too big (photo here is on a 15.5" laptop screen), and will fit in the pocket of my laptop bag without taking it all up.
