AKG K271MKII or AKG K550

im pretty sure the k550 is better, and probably more expensive. its pretty new, so it may be hard to find good reviews of it. the k271 is tried and true, and sounds much like the k240 that i own and love

"Bought the K550s to replace my AKG K702s, which still I love but my wife complained about sound leakage during late night listening, since they are an open design.

Virtually no sound leakage (in or out) with the K550s. Very private listening.

While the K550s are not self-adjusting, they are definitely more comfortable than the K702s, which have those little bumps in the headband that dig into you head after a while.

Build quality seems excellent; certainly no flimsiness, especially for a folding design.

Fairly lightweight for headphones with a framework that contains a lot of metal.

While these are not as open sounding as the K702s, they do seem to have been carefully tuned to avoid the "closed-in" sometimes "boomy" sound that many sealed headphones offer.

In terms of general sound quality, I did not find them lacking or weak in any particular area.

Maybe a little too sensitive, but they are intended for home and portable use.

You would definitely have to spend a lot more to get better-sounding sealed headphones.

Just wish they had a detachable cord."

The K550 is one the brighter side of the spectrum, but I did not find it unlistenable. It has a larger soundstage than any closed can I remember, with maybe the exception of the D7k (been a long time since I've heard one).
