No. What matters most are sound quality and operating convenience. An 
important advantage of a boom mic headset is that it maintains a 
constant distance from the mouth -- loudness varies as the square of the 
distance, so it minimizes variations in loudness.

The only shortcoming of the Yamaha set that I've run into is the 
fragility of the cable. I'm hard on cans, and I've had to replace them 
twice over about 12 years.
