USB Powered 3.5mm Audio Laptop Speaker CL-SPK20138 Clip-On Soundbar - Portable Compact Travel Stereo Speaker Bar Design Uses USB for Power 3.5mm Jack for Audio Black.

This speaker works perfectly. It is advertised as a USB powered speaker but still requires to be plugged into a headphone jack as well. The sound is great, and the volume is easily adjusted from the source.

THIS THING IS RIDICULOUSLY LOUD!!! It also isn't tinny like I expected. It isn't exactly full of bass or the best speaker ever, but holy moly, this thing does the job. OK, I'm not a fanboy for anything, but I rarely if ever come across a product that actually does what I purchase it to do. Every other desktop or portable speaker I've ever purchased was clearly made of junk and useless bits. They never work like you expect, even when you spend upwards of $50 for a portable speaker. So, I'm about to gush a bit about this Connectland one, deal with it. For a cheap speaker it is LOUD, and the sound is full. I've listened to MLB announcers, and just a few moments ago listened to some varied styles of music. This speaker finds its comfort level in the 50%-65% of full volume range(on the PC of course, there is no adjustment knob or slider on the speaker) . Over 70% of full volume the sound washes out a bit but keeps its fidelity all the way up to 100%. I'm listening to Lamb of God (who remembers 10 years ago eh?) as I type this and while it isn't full and perfectly clean, it is leagues, LEAGUES better than even the desktop set of CA and Logitech speakers I've blown through in the last few years. For someone using a desktop, these would be useful if you don't have the space for a more expensive set, but for the cost you absolutely can't go wrong with these. I'm right now going to order another one to keep in my laptop bag to travel with. To address the main issue in other reviews, yes the way the speakers "sit" on top of the monitor make it fall off onto the keyboard if you tilt the screen past 90° toward you. If the screen is leaning back it sits perfectly. An easy fix, you could just take a couple of the mid to large sized binder clips and clip the thing to your screen. Not optimal I know, but you're also not shelling out the big bucks for a high end speaker here. In regard to the speaker and primarily the SUPER BRIGHT LIGHT BURIED IN THE FRONT OF THE SPEAKER I'm just going to set the speaker behind or under my laptop and let the sound amplify a bit in the room. It's a bit more muffled, but I don't have the bright light in my face and the sound is already so loud that it creates a bit of a surround feel. Seriously, it sounds great. Lastly, if you're the kind to use the cheap style desktop speakers with a cheap subwoofer and two dinky desktop cans, throw those away. Buy this, an audio jack splitter, and a USB hub, and put one on either side. No, they won't be true stereo (unless you buy an R/L splitting jack, wink wink) but the sound is absolutely worth it. All in all, this is absolutely worth the $11 or so I paid for it, and while on a budget, I'm going to buy another right now to ensure I always have one available. Buy this. You won't regret it. It's awesome. I'm going to buy another one ASAP!

Works well, simple to use

Works great. Sound quality is acceptable for this small speaker. However, the speaker does not fit tightly on top of the laptop lid. Using Velcro really helps stabilize. Put one piece of Velcro on the back side where the lever attaches to the back side of the screen and two small pieces of Velcro on front (left and right) where the speaker makes contact on the top of the screen side (it will stay in place nicely).

Very good, compact speaker. Only issues(minor ones) that I have are, the sound is more on the base side and with it sitting on top of the laptop screen, it is quite loose. Prone to falling off. Installed velcro in front and in back to secure it in place.
