Nice fit, good noise canceling	June 4, 2011
Reviewer: Andrey Baldin from Moscow, Russia

I need a headset (with mic) with active noise canceling to use it with my laptop in noisy environments. This HMEC-250 has a good price/performance relation, pretty nice noise cancellation.
To use it with a PC/laptop you need .206 to 3.5 mm adapter (street price ~$25).
