Leakage doesn't really matter.
I had the V6s many moons ago and loved them. Tried the Aviator at a Target the other day and was suprised at how good they sounded. And their warranty is unbeatable. Lifetime? And they give full replacement?
I have never tried the M50s.
I currently have the AKG K81 DJs and really enjoy them but am looking for something new. I am not a bass head, but want it to be there. I hate flat sounding phones. I listen to DMB, Coldplay, Mumford, Avett Bros so on....mostly. Lots of 90s rock and some 90s rap.
What say you?
$150 max budget.
