Seconded. There is no better for the price.
I am currently using SR125i's which were a bit more expensive than OP budget at £170 but I've seen them for £150, however: bang for buck the SR60s and 90s are perfectly fine (60's are 90 quid). They are semi open though and very leaky so be prepared for angry prods from anyone who happens to be in the same room who may be trying to listen to something else.
I was on a train some years ago, relatively empty coach, listening most likely to Massive Attack or something with a shitload of bass anyway.....and the conductor comes up....so I get me ticket out...he says, "Nah, I don't need to see that." So I thought, "Here we go, someone's complained."
He just smiles and says, "Where d'yer get them 'eadphones, la, they look boss and I can hear the bass from here!" Result.
