Heh, because of all the “mid price” headphones all turning into different Dre copycats, I’ve actually kept using a pair of £17 Panasonic’s that I bought in 2008 for an emergency university audio editing deadline situation. They weren’t the best I could have bought for under £20 back then, but now, listening to the awful cans in the shops, I think my cruddy old Panasonic’s sound better than anything in the Sub-£60 category, let alone the Sub-£20.
Everything’s about the bass. Even if you specifically ask for headphones designed for a good rock tone you get a set of cans that can’t provide any sort of clarity in the mid-range at all, it’s an awful combination of tinny highs and ridiculously over the top bass that isn’t even defined all that well besides its ability to go BWOOM.
I’m not being snobby over music genres. I listen to a range of things, from the odd classical hit thru punk rock thru death metal thru industrial thru electro so… yeah. The one uniting thing for all those though is their total lack of requirement of BWOOMability in headphones.
