My thoughts would be to save a little bit more and get the best you can afford
The 1st pair I bought were Sennheiser HME100 very light very good
Sennheiser HME 100 Passive Headset with included Sennheiser Case £194.99
a 2nd hand pair on flee bay
Pilot/Aviation Headset Sennheiser HME100 on eBay (end time 07-Aug-10 20:13:05 BST)
I then bought a Clarity Alfot in the ear thingies and love them to bits
Cheers
