I've used the Telex 750, Telex 850, Sennheiser HMEC 25-KA, Bose A20. I've also used David Clarks way back long ago.
Telex, rubbish. Poor sound quality. The 850s are only marginally better.
Sennheisers, excellent quality. Used them for 7 years with no issues. Now serving time with an easyJet pilot.
Bose? Awesome. Love them. A bit heavier than the others but with both passive and active noise protection, well worth it. Sound clarity is fantastic and will work if the batteries die. Intelligent battery power consumption too.
Excellent customer care too from Bose. Very important.
If you were heading to the bush I would say DC as they are bullet proof.
