Works as advertised. Good sound, volume and connectivity. Recommend

Works GreatJune 6, 2025

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. Read more

Greatest Conference/speakerphone ever created

Ian McJuly 18, 2021

After 2 weeks of use, I feel I can give an honest review on this conference phone. When I first got it, the first thing I noticed was it’s small size. To test it out, I called my mother - because I knew she would answer. She, of course started talking about the weather. I couldn’t hear a thing. I was very disappointed and felt frustrated and got off the phone with her. I tried playing music on it and still felt it was hard to hear. That’s when I realized the volume was almost turned all the way down. DOH! Once turned up, I played another song that accentuated bass and it sounded great, but I felt it was still lacking something. I moved from my bed to my desk and once I had the device on a solid surface, THAT’S when I heard its full potential. It’s like it uses the surface of the desk to echo the sound out. I’m kind of an idiot so this might not be the case at all, but either way, definitely use it on a solid surface. Once my girlfriend got off work, she called and couldn’t tell that I had her on speakerphone (which she HATES!) and so I could finally free up my hands and do other things while on the phone with her. #winning. The following day I took the device to work and made several calls with it. The noise cancellation works flawlessly. Even had a coworker notice it and called over to my office to see how clear it was on the other side. He said it was as clear as any call he’s ever heard. The following Tuesday I had a legit conference call between in a meeting and it worked great. Had 3 of us in a conference room on the phone with 2 different callers. After the meeting I was asked about the device and recommended it to the others. I think my coworkers will be buying their own if they haven’t already. Definitely worth the price if you have regular work calls or spend any time on speakerphone or conference calls and want/need your hands free. The one thing I wish is that it came with a longer charging cord, but easily found a longer quality charging cord that sits on my desk for when I need to charge it - usually at the end of the day (just to have a full charge the next day, but it still has plenty charge after just one day). In the end, definitely recommend this product and if you don’t have a desk terminal with USB ports, a longer cord (or desk terminal) for charging is definitely a plus. This is one powerful device, especially in relation to its small size. Can’t wait to try other products from this company! Read more

Great, simple, versatile and they just work. Sometimes simple is better

Aaron E.December 23, 2025

I am specifically reviewing the non bluetooth version of these. They are great simple speakers. I have gone through a few different more expensive speakers for people that have been just horrible for people with laptops and docks. The other speakers turn off if the laptop is not docked. Require reconnecting to bluetooth if they take their laptop back to the office and need to use the speakers. These just plug in and work. No power button, no bluetooth. And because USB A ports are almost always used up on the docks, having the USB A to C adapter is a godsend. Sound is perfectly fine for office computer speakers. The only issue i have is that the clamp is not wide enough for some monitors. Two stations, 1 has curved samsung monitors and they will not clip to the bottom. Another station has the same size and curved monitors but different brand, and they clip on and look great. If the clip was just a little larger I would give them 5 stars. Read more

Price, Quality, Everything… Absolutely Incredible

Kindle CustomerNovember 19, 2025

Honestly, I’m extremely satisfied with this. The price and the quality are both insane. I wasn’t expecting much because it’s small, but the sound is clean, clear, and way better than I thought. Bluetooth connects instantly, and it fits perfectly under my monitor without taking up space. Overall, this thing is just genuinely good. I’m really impressed. Read more

Great supplement to your on board speaker and microphone

Jon CDecember 3, 2025

This is a great little addition to your setup, especially if you video conference frequently. Works as advertised, it’s a wired speaker that can also work over Bluetooth. Microphone is built in too and the best part is it has a physical mute switch with red/purple indicator lights to let you know when you’re muted. Works great for work from home folks. Read more
