The build of this new k550 makes me think- It probably will be quite different from the original k271.
Still, the k271 is the special one.
My view on the k271
I mean, people go in the market for a phone with say certain specifics: Closed, Isolating, circumaural and sounds good.
And in my view, these are definately a top tier for this market just for the sound. In Soundstage dimensions and imaging it beats the ed8, d2k (sometimes), dt770pro80, a900, which I have tried. And in speed, resolution (tied with the ed8), and general dynamics within the highs and mids spectrum. Bass sometimes lacks in only quantity for me sometimes, but I don't give a monkeys. And it sounds good through whatever I play it with. With the cowon i9 'bbe headphone' setting, wow!!
Oh and before I say more, in the 'non sound dept' it impresses further. The lightest of them ones I've mentioned, most comfortable headband, surprisingly nice velour/ pleather pads and a relatively light cable. Perfect clamping force. And a surprisingly useful auto-mute switch that shuts off when you take it off.
BUT only one thing seems to impede its claim of a true top tier....
...the price!!
Actually, I've only realised this now, but for me in the uk it was the cheapest out of them ones I've owned.
Conclusion
This serves to proove to those wrong, who worry about having to spend loads of $$$$ to get a top tier sound. You have it here with the k271mkII
