Works as advertised. Good sound, volume and connectivity. Recommend
QUICK SUMMARY: -It works as expected. -Good sound quality (not excellent, it's not a Bose speaker) but good. -Works for Zoom and Music. -Easy to set up and use. -Would recommend. MORE DETAILS: I have an older monitor and the speakers on it started failing so I began using the audio on my laptop that is to the side of my monitor. It probably seems silly, but it was bothering me to have sound on one side.. my right ear started feeling funny - I don't have a better way of explaining that right now - but ultimately, I knew I needed to have the sound come from the middle of the monitor. This speaker does the job as advertised. It has a clip so you can clip it to the top or bottom of your monitor. I put mine right in the middle, bottom of my monitor. It clipped on fit fine with no issues. The part of my monitor I clipped it to is between 1-1.5 in. wide. As far as fit, I'd say this can accommodate most monitors. If you need this just for your computer, you can get by with the cheaper non-bluetooth version, as if it's just for your computer, the speaker's USB cable needs to be connected for power... for me, connecting it to power also means connecting it to the computer therefore the bluetooth is not needed unless I decide to connect my phone to it, which is unlikely. I connected the USB and it popped up as an option for audio right away. I haven't had to use through bluetooth but I did connect and it worked fine. You can also use this as a mic. I don't use it because my webcam has a mic, but if needed, you can use this for that. The sound is clear and works great. The volume controls are great, you have a good range of volume. I appreciate that as sometimes I need some music/sound without being too loud to distract me and had previously struggled with the volume controls of the monitor that didn't allow a wide-range. I use it for work meetings through zoom and have had no issues, just changed my speaker option in the zoom app - keep that in mind. Sometimes with Zoom, selecting the speaker for the computer itself is not enough, you have to go to mic, the arrow on the side, and select which speaker you want to use. I've noticed that Zoom trumps this setting over the computer. Overall, this is a good choice and for the price, a solid buy. Would recommend.

Great Sound for Price and Size
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.

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.

Good Sound at an Affordable Price Point
I'm pleasantly surprised with this speaker. The last one I got was of another style and type and a poor performer. This one is clearly better right out of the box. My monitor turned is huge and out to be too thick to mount on with this clamp. However, I have a book shelf right above the monitor and was able to easily clip right on at arm's-length.

Stereo? I am only getting the left channel
I have not tried the Bluetooth usage. I thought this was Stereo (It said it was on the listing), but found that I do not get a right channel out of it. Tested on multiple systems. I bought this for better sound on my monitor that I have connected to my bedstand. Sound is better than the monitor sound, deeper and fuller sound profile... but only on the left channel. No right sound at all. I have tested this on windows 10 and 11 on three different machines, just to see if it was a machine issue. I am not sure if this is a recent thing, or if it came this way, as most of the stuff I listen to with it does not really have a stereo need so did not notice it until I had something that used both channels independently. Surprise, could not hear right side. Pros: - Mono sound is good, deep and fuller sound than most default monitor sounds - Good volume Cons: - Only plays left side sound - Monitor grip is a little long for the top of the two monitors I have tried it on, so I have to lift it off a bit to stop it from occluding the screen, which makes it fall off every now and again and swing from the back of the monitor (I have it anchored at the back)

5-star Customer Service & Brand Integrity!!
Within a few months my bar started to sputter and distort sound when taking calls - of course this was just outside of the Amazon return window. However, once I got in touch with Cyber Acoustics customer service, they handled my issue promptly. After some light troubleshooting, they determined my product defective and quickly sent me a replacement overnight. AMAZED and impressed with the business who stands by its product and customers in today's throw climate.

Good VFM speaker for PC
Sound quality is superb. I got this because the speaker assembly of my aio pc broke down after service center guys opened it. It's a USB plug and play. No need to pair via BT. If your aio has a thick bezel then this may not be useful at the bottom. The size is appropriate - not too big nor too small. The performance is adequate - it's doing the job it was bought for. Insanely good value for money product. Would highly recommend this.

Fits my monitor - smart and doesn't buzz
I've got this speaker attached to the top of my monitor where it's completely out of the way. It grips very securely and is exactly what I needed to replace the tiny buzzy speakers I had before. When not in use it's silent and the sound quality is great for video calls, occasional films and music. I don't use it at high volume, it's on my home office computer. Set up was really easy - I just plugged it in. Great price. Recommended.
