Personally, I think a lot of people walk around with the bloody buds in their ears just to justify ignoring the world. Unless you superglue the things in and seal them over with wax, so much ambient environmental noise gets around them that 'listening to music' is rather ridiculous. Now if you say 'listening to music, screaming kids, yakking old ladies, ambulance sirens, dogs barking, truck engines roaring etc ad nauseum', that would be a more accurate take.

 

And I luuuv my Sennheiser HD 380 Pro's. Ghu knows I wouldn't dream of mixing music or foley without them. He who doth not listen to mastering with as close to flat freq response headphones or speakers will be rudely stunned by the difference his finished product has from what he thought it was.

Plus the things are so comfortable you can wear them for hours..... :D
