I joined this ownership crew sooner than I thought I would, but then my birthday came and I got mischievous thoughts.
I'll not say too much about construction, looks etc. After-all, it's more about comfort and sound. Despite their weight, I find them to be quite comfortable and can be worn for long sessions.
I'm very impressed with them. Very impressed indeed. I've come full circle and found my way back to a more balanced sound. There's a lot of that to be found in these HD800's. When I listen, the words refined, tidy and disciplined come to mind. A nice level of intimacy is achieved without the sound ever getting too close to my ears. This makes for a very engaging listening experience with the added bonus of no fatigue. Excessive intimacy and colouration are the main sources of fatigue for me (Grado's anyone?), even though such presentations can be ear-catching on the first take.
I haven't been experiencing excessive brightness from them and this has been the case since I first put them on. I've thrown some of my harsher test recordings at them, and in Sennheiser fashion, I don't have to grimace and reach for the volume control. Very well done indeed.
I don't find the sound stage to be too open. I actually find the sense of head space and ambience to be quite natural. The level of detail comes out a LOT with the full worth of the HD800's coming into being, when listening to very good recordings. However, with a lot of contemporary recordings, the HD800's do not particularly stand out when compared to the mid-tier wonders like the HD600's and K702's, and seem to be just another nice can. I can easily imagine someone listening to these latter recordings and judging the HD800's based on this.
So far, no boredom whatsoever, but just the music which may make me tap my toes, bob my head or lean back and close my eyes. I already found this experience in the HD600's and 650, but the HD800's achieve it in a technically superior fashion. I personally think the price tag is reasonable given the sonic performance I'm hearing. I have no regrets with this purchase and am now quite content. I currently have no desire for more detail. This is enough for me. So definitely, no electrostats and likely no balanced. The HD800's are great with my current amp.
