This is a review and detailed measurements of the Sennheiser HD 800 S. A very kind member sent these months ago and has been patiently waiting for their review. The HD 800 S costs US $1,700 but I see it on Amazon for US $1,323 including Prime shipping.

As with speakers, let's also look at distortion level as opposed to percentage:

As I noted, the best way to know if our preference curve is correct is to try to approach and see if the subjective results are better. So let's do that:

I have eliminated the headroom allowance to make the graph easier to read. In reality I had to dial in 6 or more dBs depending on what I was playing to avoid digital clipping. You have a trade off between how much you boost the bass and the headroom you need to allow. I love the clean presentation of deep bass from headphones so dialed in what the preference graph said and results were excellent. My "speaker killer" tracks with their sub bass sounded wonderful. Despite the sharp rise in the distortion graphs, there was no penalty that I could detect in that department despite the high level of boost.
Next job was to fill the gap between 1 and 4 kHz. That is a complex shape to fill in but I approximating it by putting in the conjugate filter to knock off the resonance peak at 5.4 kHz. Once there, I thought the result was a bit bright. A quick shelving filter of 10 kHz solved that problem nicely.
The overall tonality was still "light on its feet" for lack of a better phrase to describe it. There was this lack of congestion and ease to everything I played. What was remarkable and uncanny was separation of instruments. It was as if this headphone would take every element in the music, pull it apart, and then position it in different spatial locations in a 6 inch space around each ear. I wouldn't call it "soundstage" as much was it was this fun and captivating effect.
I made a comparison against the HD650 which sounded far more balanced and nicer than HD800S without EQ. With EQ, the HD800S sounded a lot more competitive and that had the above layering that the HD650 did not have. ...
