After my first few lessons and an introduction to sweaty grotty headsets that were so tight (not adjustable) that it gave you a headache I got my self a set of DC's. Then in the US on an hour building trip I got another set for about the same in USD as I paid in quid. If the US isn't an option for you there are some reasoanably priced sets for your pax but spend a bit of money for yourself as it will pay dividends.
