I had a hard time at first. Brochure does not explain in detail about the sound. I had to type model number on Google and found out how to use it.

USBに繋ぐだけで音もビビらず、われもなく普段使いには全く問題ないです。ただし、今もう一つ購入しようとしたら倍近い値段になっていて購入に躊躇している。

This is such a nice speaker for home meetings in Teams/Zoom. The sound is clear and the noise cancelling does it's job really well. It's easy to control meetings from just the speaker and it fits right on top of my desk, taking up barely any room. For the price, this works just as well as my other one that was double the cost.

If you are only streaming voice this will do, but you won't like it for music.Pros: Looks good clipped to the bottom of the monitor, saving desk space. Bluetooth connects immediately. No audible hiss when not playing sound. Wakes up immediately when stream starts. Plenty of volume for listening at the desk.Con: Music sounds very tinny, with little midrange and no bass. Sound is slightly better when plugged into USB C for power, worse using USB A (per user guide) . You have to push a button to engage the added boost. Control buttons are hidden beneath the unit where you can't see them, so you are left to guess which ones to push.I tried an equalizer app to increase midrange and bass, but got only distortion. I'll probably keep it since I don't use it for music, but I wouldn't buy it again.

Sound is clear and plenty loud. The form factor is very small (exactly what I wanted), so don't expect much stereo separation or bass, but still better than most laptop speakers. I don't have a very thick monitor, but it just barely fits on top of it. I probably wouldn't use this for gaming in a game where spatial audio cues are important.I like that the entire thing is supported by a single USB cable.

Didn't expect much from this speaker, as it looked quite small online. It clipped to my Samsung computer monitor just fine and connected without any hassles via my usb hub. Sound is good, there's a decent amount of low-end to the speaker, and while it won't be doing any booming sub sounds, its excellent for a basic computer monitor speaker.Only downside to this speaker is that there is no power switch at all, once its plugged in, its working, and it has a bright green led that cannot be turned off. Would have been nice if there were a power button or switch for when I'm not using the computer (which can be days at a time in my case), and for now I just disconnect the usb cable from my hub.

I have three monitors at work. When I'm in meetings online, which is a lot, it was hard for me to hear with the monitor speakers. It was also hard for people to hear me at times. This speaker has good sound and I can adjust the volume to be very loud (more than I need). It also has a built in microphone, which works well and people say they can hear me clearly. Definitely a good product and good price.

This speakerphone is so easy to use that it can be turned on even when a call comes. It has a very good sound quality for a such small speaker. But it must be placed on a solid surface as a table. Otherwise, the sound will be weak and poor quality. I like it and use it daily.
