I think the PRO 900s are an amazing pair of portable headphones. Comfortable, sexy, light, isolates, and stays on the head.
They are so much better than the PRO 550s I can't put into words. The fact that I enjoy listening to them almost as much as my LCD-2 says something. They are best with Electric and Rock music, IMO, but piano bands like Coldplay and Bed Fold's Five sound great as well. No pop/rock song is bad on these.
Right now, I think I am going to order both a Moon Audio Silver and Blue Dragon cable. The Blue (Copper) gives the the bass crazy quality and improves everything with a close sound, while the Silver makes the bass tamer but more detailed and makes everything more clear with a laid back sound (The Black Dragon is the same as the Blue but also adds bottom end, which is not needed on the 900s). Judging from reviews, both have their pluses and minuses so I have no idea which one will sound best with my portable player. Will test them out for a month and send one back (with no restock fee).
That Amazon store has three left. I really like them.
