Review on CMTECK ZM330 USB Microphone Speakers: Enhanced 360° Voice Pickup for Efficient Streaming, VoIP Calls, Skype, and Interviews by Jamie Eddington

This little device is great for the office or when travelling. The USB cable delivers the power you need, the controls are easy to understand and use, no driver installation required, plug it in, switch the software to use it as a speaker/microphone, installation is complete. I use it for private calls and gaming. Music through my laptop, it works well as a speakerphone in my VoIP applications, and with no connection issues, the audio from the speakers is loud and clear too. I like the freedom of being able to walk around the room without having to put calls on hold or carry my laptop around.
