The official subjective review and many others' impressions can be found in this thread. Any subjective impressions here will be brief and are mostly consistent with what some others have already observed. I passed around the headphone at work among non-audiophiles or entry level audiophiles. The comments were "slightly thin or bright" with respect to tonal signature. Depending upon the recording, I did feel the XC retained a bit of that upper-mid "honk" (more precisely a peak around 2kHz) from similar type of closed Audeze I heard many years ago. Or another way to look at this is thin - a lack of body - often the result of slightly recessed lower mids or lows. All these impressions BTW were gathered before I took a single measurement. The "technicalities" of the XC are excellent. One thing which I have been curious about are the EQ profiles which Audeze provides for their high tier headphones at a modest fee. Roon actually includes these profiles; so naturally, this was the first thing I wanted to test. Audeze LCD-XC Frequency Response (FPC compensated) GRN = no EQ, YEL = Audeze LCD-XC DSP preset on The LCD-XC DSP profile isn't an extreme EQ profile which tries to surgically correct everything (this is a bad idea for reasons that can be discussed elsewhere). As a result, the DSP profile corrected the board 2kHz bump, but it also pushed down the 5kHz dip. I would say however that the resultant sound with the DSP profile is much closer to the Audeze house sound that we call expect from the open LCD* series. Not to harp on this more, but I felt that Audeze didn't need to print the big "Audeze" letters on the cups. The carbon fiber pattern is beautiful and otherwise ruined by the lettering. A tastefully small Audeze A logo (it's a nice logo) on the cups would have done the cosmetics more justice. I'm not the type of person who wears the real SUPREME gear with the hidden tag, not the obviously fake SUPREME with the letters loudly printed over shirts or shorts.
