I purchased a second hand set of DC10-60's on ebay for £110. I got on that well with them so when i started instructing i got myself a brand new set and my old pair is now my student headset and seems to take the punishment and lack of respect they all give to them. All the instructors where i work use a DC headset of some description. The school being thee school have 5 Cheapo Peltor sets, these are rubbish by comparison!
Hope this helps!
