Difficult to answer this without mentioning brand names so:
Mr Moderator this is for info only, I have no connection with the company and wouldn't advertise their stuff if they paid me coz I think it's cr*p!! 
Here at EGGP we use the Airlite 62 headsets. Somewhat "agricutural" but they last for years.
Marks out of 5:
Comfort: 3
Reliability: 4 (easy to fix)
Value for money: Don't know how much they cost so can't say.
Style: 0
We have trialled others in the past; Jetlite (the black plasticky version of the above) was given a good run but was rejected on the grounds of durability.
