i know i have closed this forum but i wanted to let you know that the Sony MDR-1R's i have ordered, arrived today. they sound really good. their soo comfortable, its ridiculous. Comfort wise comparing to the my brother M50's, the M50 are a little heavier and quite tighter on my head and im not able to listen to the for a long amount of time. The ear cups are noticeably harder than the 1R's, the 1R's feels like you resting for ears on a set pillows.
sound wise i don't really have the expertise to be able to compare however the only way i can explain it is that the 1R's are more open than the M50's and that's probably becasue of the angled. drivers. bass wise, after listening to Daft Punk- Random Access Memories on repeat, the 1R's appears to me, to be more tight and have more impact than the M50's, however at times the bass can be a bit a bi too much to my ears.
unfortunately theirs a nasty scuff mark on my 1R's right ear cup, thankfully the seller is more than welcome to replace them fro me. i bought them for $247 at a Sony Clearance Store in Brisbane.
amp wise, i bought the Fiio E07K, i think it improves the MDR-1R's all around, their isn't a huge difference however it's substantial.
i'm really glad to hear that you like em! :)
