I haven't personally owned the M60s, but I do own a pair of M3s as well as the VR3s. Honestly, I think the performance from either one of these will be very similar and will come down to personal choice or preference.
I was comparing these two a couple of years ago and it came down to which one I could get for less money. I went with the VR3s having scored a very good deal on them and I haven't regretted or had buyer's remorse on them once. They deliver very well with music or movies. The better the source has become, the better they shine.
Whichever you can get cheaper, I'd go with them. Either way, make sure you've heard at least one of them to make sure you and/or your wife like them to begin with... -TD
