Decent headphones for music < £100?

[HungryHippos]

I have a pair of Phillips X1's at home, sound awesome but open backed.

My in-ear headphones at work just died, I've had so many pairs of these things die that I am tempted to just get a decent pair of proper Headphones instead.

Anyone got any recommendations for decent ones for sub £100? Office environment is quite noisy, active noise cancelling probably isn't required, but if there is a pair that will block out some external noise too that would be great.

Yeah I want to stay away from in-ear this time, I literally have to get a new pair every 6-12 months, one ear will go, then the next sometime later.

DT770's actually look pretty good, what is the difference between the 250 ohm, 32 ohm, 80 ohm versions? I will just be driving it with on-board soundcard from my work computer not a dedicated amp or DAC or anything.
