beats by dre mixr vs bose qc15?

NEITHER. Beats are UTTER RUBBISH and Bose WAY overpriced and WAY overrated!

If REAL quality is an issue, you should stick to REPUTABLE brands only such as B&W, Sennheiser (most affordable), Shure, Grado, Denon, AKG, Audio-Technica (NOT to be mixed with Technic which is utter rubbish as well!), Etymotic or Beyerdynamic. Things like V-Moda, Klipsch, Sony, Panasonic, JVC and Philips are ONLY "okay-ish" indeed. Please do NOT fall a victim to FASHION ACCESSORIES by buying Boombox, Ministry of Sound, Sol/Republic/Revolution, Noontec Zoro's, Benetton, a-jays, iFrogz, Marley, Fanny Wang, Razer, Karl Kani, WESC, Turtle, JH, Dr.Dre/Beats/Solo, Ludacris/Soul, Koss, Skullcandy, Lady GaGa, Skullcrushers, Monsters nor Bose, because they are ALL seriously overhyped and overpriced "fashion blingbling gimmicks" with a very poor durability and sound quality, NOTHING else (and those who try to claim they are good do NOT know ANYTHING about QUALITY anyway!), BE THEM FAKE OR NOT!

Also, please do NOT focus on the thumping bass that just distorts everything else, instead go for GOOD audio quality IN GENERAL.

I never liked bose go for the beats
