The new Plantronics .Audio 610 headset has some unique benefits:

• The headphone covers only one ear, so you still have a free ear to hear what is going on around you.
  
  
• Mac and PC compatible. You can use it with standard analog PC sound cards, or plug it into the included USB adapter dongle, and now it is a USB 'plug and play' headset. USB-HID audio compliant, no drivers required, it just works on any PC or Mac.

• USB-enhanced digital sound quality
  
• Noise-canceling microphone
  
• QuickAdjust boom for precise positioning of the microphone
  
• Lightweight and comfortable for hours
  
• Analog or USB connection flexibility
