I need a new pair of headphones but I can only afford to pay around £25-30. Can anybody advise me on what's available for that price that has a reasonable sound quality. I currently use a Nad 3020e amp. I do have a Kenwood amp (can't remember what model) but it needs repairing as there's a problem with the headphone socket (you may be spotting a connection here!), I have an Arcam Alpha CD player and Sony mini-disc player. Any advise greatfully received.
