Now you guys know just how awesome the JVC SZ series cans are, and just how low they can really go. Not many cans can hit that 20 hertz range well. And not that many cans can be turned up as loud without piss poor feedback being heard. But the disadvantage to them is the fact that they are not plug and play cans. They need EQ and they need amping, that alone makes them not an ideal choice for portable, if the imense size and weight are not obvious to you in that regard lol. But I think that for in the home use they are the perfect choice for any basshead. Its like having a sub woofer attached to your head. But the thing I like about these cans is that they EQ well, so if your someone like me who appreciates bass, but also likes highs, you can raize them up to +10DB or more, and have your ear drums blasted to your content of bliss. I personally know of some cans that have been reviewed that had way too many highs out of the box without EQ and have next to nothing for the bass. Those are usually the overpriced open ended cans though, their the kind that most audiophiles will try to sell on you that you need some studio grade 3000 dollar monsters in order to be happy. That is just not so. And besides, you can't take an open ended can with you on the bus, that is unless you want your stranger neighbor to know how much you like Lindsey Lohan porn while midday.
