Can I judge them? I mean, I own them and all.
First off they are NOT closed back...
Second, they sound like $30 and nothing more. These phones have just gone to prove to me that people are brand sheep and it's sad.
Even after mods the bass is bloated and not punchy at all and creeps into the mids and the highs are sibilant and grating as hell. *blech*
If the above sounds like your cup of tea then you may love the JVC's. However, if you would like some real HI-END phones for $30 then buy the Maxell's - I swear to God that they **** stomp the JVC's in every single category.
