I have a several pairs of IEM but im moving away IEMs. I want to get a decent pair of headphones with MASSIVE BASS! If the headphones had a mic on them that would be perfect too. I own a pair of JVC Xtreme Xplosives HA-S4X and I owned the HA-M5X but I preferred the bass of the HA-S4X. So if anyone knows of a pair of headphones that has that great, MASSIVE bass I would really appreciate it!
