JXC - exactly the same Sennheisers as me - from skygeek too! I'd recommend to anyone.
Had a cheap nasty pair to get me through PPL (came as part of the course price) but when I was doing my hour building of anything from 2-8 hours a day, I soon realised that a decent set were essential...couldn't afford the Bose X's so went for the best combination of affordability and quality.
The Lightspeed range of headsets came a close second in my final decision...
