Summary: Purchased to use for off-site web-based meetings for work. Used once and the audience complained of poor quality sound, horrible breaking up. When I tried to mute it - it would not allow me to unmute easily. Had to use alternative phone. Did not stay on my ears well/slipping. Have not used since.
Summary: A cheap headset that's comfortable to wear and works well as a mic (my friends no longer whinge at 'hissing' in the background of my skype calls). Speakers are perfectly adequate; not hugely bass-y but these were so cheap I don't feel I can complain about this.
Summary: I purchased this as a replacement for Plantronics 345 (http://www.amazon.co.uk/Plantronics-Behind-Enhanced-Multimedia-headset/dp/B000VDB0DW). Seconds after putton on the 646, I wanted to take them off and return them.
Summary: I've used a few different headsets over the past 6 years but all have been conventional top of the head style. I decided to try a set of Behind the head style and I'm glad to say I am delighted.
Summary: I use PC headsets a lot! as I use them to dictate into the PC. This headset is comfortable and discreet, the microphone is positioned sensibly so you can drink a cup of tea without moving it. the accuracy of the microphone is very good.
Summary: Pros: 1. Actual product size is less than the product visuals 2. Length of the wire 3. Plastic quality 4. Easy operation for operating the volume and mic operation 5. USB operation and DSP technology for enhanced audio quality Cons: 1.
