I also got my X1 last week. The sound is very smooth. Everything is so detailed. But treble is lacking. I compare X1 with ATH-m50. M50 sound more clearer due to treble presence. But I love X1 more because X1 give a very smooth sound. Probably due to the awesome mid. I still using original cable. Should I just take any cable like the one from TBSE1 and use it? Will it spoil my X1?
Here is the photo of my X1 with the rest of my cheap headphones:-
