Query: EXCELLENT VALUE; my Skype contacts WANT TO KNOW!!!

A most versatile item: fine for music, online gaming, transcription, and especially for VOIP like Skype, Google talk, etc. Some of the reviews, especially the negative, compare this model to the higher-end Sennheiser noise-cancellers. Those models cost almost 10 times more...I routinely make Skype calls from noisy environments. My Skype contacts, during these conversations, consistently want to know the brand & model of these.
