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: 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 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.
Summary: Tragekomfort auch bei längerer Benutzung sehr gut, kein Bügel, der auf den Kopf drückt, Praktisch ist die Mute Taste und die Lautsärkeregelung am Kabel, Sprachübertragung ist super. Ich hatte zunächst einen defekten bekommen, Umtausch war kein Problem.
