You say hd 439 is good but isn't the hd 449 better? I thought the hd 449 was an upgrade to the hd 439? :-)
The HD449 pads are pleather and may need a new replace after 2-3years of use where as the HD439 pads are velour; it won't make your ears sweat and it's more comfortable, as for SQ,the HD439 have so slightly more bass (lower end of the FR), and it's slightly darker as well
