ATH-AD700s, small dent in the right cup though where I fell asleep in them. These headphones are so fragile!
How are the UE700s? I'm looking to buy some new IEMs. At the moment I'm using some Klipsch K2s which I bought for ~£20. I originally planned to not spend more than £20-30 on IEMs as I stuff them in my pocket with my zune and I used to break them all the time.
However, now I've Klipsche K2s and realised the reason they were breaking was due to the Senns quality problem (known issue with one bud going after a few months) on the CXseries rather than me abusing them I'm tempted to spend a bit more on them considering I probably spent equal amounts of time listening to my IEMs out and about as I do in my room with my ADs.
Also, +1 on the monster headphones.
