I own both the 600 & 650 & I think they are both fantastic phones. Actually like them both more than the 700. There's certain music I listen to where the 600 performs better and vice versa. But from my experience I think they both sound better on an otl amplifier. I've also got a violectric amp which drives them well, but I perfer the warm lush sound of tubes with the hd series. Now that the weather has changed I can wear my sennheiser sweat shirt when I gear up. Cheers
The HD700 is so totally not worth the premium over the HD600. I haven't listened to both successively on the same equipment to say exactly which one I like more or think is better, but I can say without a doubt that it's not worth more than the HD600 by such a margin. I will say however that the HD700 may be the most comfortable headphone I've ever put on before and that has to do mostly with just how much space is inside the ear cups. There are plenty of headphones that look like they should have plenty of space but once the earpads compress slightly to form around your head, there's less space than you thought. Not the case with the HD700, at least for me.
