I can't quite decide between these three headphones here for Alternative/classic/hard rock music. I have not tried any of these headphones, but I do own some HD 555s at the moment. While they are pretty comfortable (Usually can wear for 5 + hours without any soreness around ears), they do have a problem with the headband. On both sides it has cracked. I'm assuming this doesn't happen with the HD 650, but was just curious if the issue was fixed or not. I've read from several threads around here that the Grado RS1's are the 'king' for rock music in this price range. I've read some conflicting things about the comfort of Grado headphones so I'm unsure if I should pursue them or not since I tend to wear my headphones for quite a while in one sitting. As for the HiFiMan HE-500s, I was recommended those based on the budget I listed, but I haven't really seen or read any comparisons on them against the RS1's. These are currently my thoughts and why I'm torn as to what to choose. Any more recommendations or thoughts on these is appreciated. I'd like to make a decision soon and make the purchase. I need some high quality music .
