PLEASE DO NOT WASTE ANY OF YOUR MONEY ON THOSE.
If REAL quality is an issue, please go for REPUTABLE brands only such as B&W, Sennheiser (most affordable), Shure, Grado, Denon, AKG, Audio-Technica, 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 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!
Please do NOT go for overly thumping bass that distorts everything else, instead focus on good sound quality IN GENERAL.
