They leak very little if any noise. You are not going to be driving your colleagues crazy with excessive noise that is for sure.
I have to agree with this. I went to my local store to listen to the Beyer DT770s. The guy at the counter said "try the M50s, then listen to the 770s after".
I agreed. The Beyer's sounded great. The fitment over my ears were great. Soundstage was excellent and I thought I was sold.
I then tried the M50s, and I could have shed a tear. It was just great all around. I played every genre from the iPhone amped through my E11. The bass just kept rocking. Especially on R&B tracks. The M50s just sound too good not to buy.
I wish I had some Pro700MK2s to compare, but I was sold on the M50s at that point. If you find that the Pro700s don't fit you taste, then I bet the M50s will.
