Koss CS95 Portable Single-sided Electret NC Mic, Dual Plug

This sounds AMAZING. I have no complaints. I do have ONE wish, that it had an inline volume control! Other then that, it sounds great, the mic offers great pick-up (while reducing background noise). I love that I can plug in the HEADPHONE plug to my mobile device to listen (the headset mic doesn't work, but the phone mic still does)

I have procured 30 of these for corporate Skype use. They have excellent noise cancellation and decent speakers. Quality of conversations with colleagues in developing countries is equal or better than standard phone handsets. I recommend this product highly.
