Ok, I must have the biggest head in the world or my head is really round like a cookie but I for myself, I think there's too much bass on this headphone hahaha.
Now seriously, I have been a reader of this forum for some years now but never had a reason to post anything (or guts too), but I bit the bullet and after some of the most helpful recommendation from a user of this forum I bought one. I have to say I had tears on my eyes the first time I listened to "quarteto novo" record. I could hear intruments and performer's placement that I have never noticed before. I spent almost 2 hours in complete trance mode.
Now I have a question to ask you guys... after all my listening I found it was tiring on my ears. And it does sound there's a lot of bass, more than I was expecting. Is my can a new veresion or is it because of the recessed nature of the beast (a lot more soundstage) that I may be listening too high? It does not sound hight at all but the bass (and highs) comes pretty strong at times, depending on the record.
I am kind of used to sound, as a film editor, I work all the time (and I am pretty used) with a pair of genelecs 8030s and I have a pair of hifiman re0. I know they are pretty light on bass, a bit forward but that's the reason I thought the k550 would be a good choice for me.
Anyway, I am in love with it, and even considering not wearing a glass anymore if it gets me a better seal. The seal is so tight with me that if I have them on, and I bite (force) my mouth muscles, I can hear them.
Or maybe I have a new improved version? When I tried them in a local Saturn dealer, I found them pretty thin tho... not with this ones.
Maybe there is some guy or girl in China in the assembly line who just bends the headband prior to assembly and so every set of headphones is different in regard to the amount of "clamp" :)
To address the sound getting tiring. This may be a separate thing from the use of these particular headphones. I have become a great user of crossfeed on my Meier Audio StageDAC (my DAC of course) and I find this to be excellent for reducing listening fatigue because the instruments are placed more sensibly in a soundstage and less likely to be effectively playing 1 cm from your ear. If you listen to music from a computer source there are software crossfeeds which you might like to try out. Those software ones have adjustability I think, so they might be quite fun to explore.
I agree with you that the AKG K550s are amazing quality for the money.
