I don't have a need to respond concerning the MDR-EX71, as Steve1000 already did this for me.

I might as well post this too
There is still not a complete understanding about what makes headphones sound good to our ears,
Actually, in a control situation[same music, same levels, some conditions], the overwhelming majority of listeners[those with hearing impairments make the majority of the minority that due not conform with this] will tend to prefer a specific sound, as shown in perceptual research. This has been shown to be true for speakers
[1]. The preference of sound of headphones is no mystery, and has been extensively studied and quantified. A preference among users of headphones, in control situations[as with speakers],
[2]shows similar trends as with the speaker studies.
some of the best headphone manufacturers in the world, AKG, Sennheiser, Beyerdynamic understand that a headphone that measures perfectly flat do not sound good with music.
Interestingly, if a headphone was to be heard as 'flat' [in a proper comparison], it would not have a flat response due to well known and understood physical reasons, including (1) the headphone must induce a high frequency gradual roll-off to simulate the natural roll-off that occurs with objects in front of you due to head shape and ear canal angle in reference to such (2) bass is tactile with speakers and real events, with this tactile sensation missing, a headphone needs to add some bass audibly to compensate (3) headphones can vary in sound depending on the person wearing them due to physiology of the ear and how the headphone interacts with the acoustics of such, but this is phenomenon is known and understood
[2], and products do exist that have little variation regardless of individual physiology, and it is understood how to make headphones with little variation regardless of physiology.
So why is the variety of speakers and headphones so high in number and preference? I believe it is important to consider that in real life, controls are not present, as were in the tests above. Music can[and does] have significant deviations of tonal balance depending on the preference of the sound engineer. There are NO standards in musical album production, after all. Also, some people just like different sounds, I believe. So of course no one headphone[or speaker] could possibly satisfy everyone. Warpdrive did point out [correctly] that an accurate monitor is not necessarily desired for musical enjoyment. I tend to agree, and I actually despise very accurate monitors[speakers or headphones] for strictly musical enjoyment purposes.
I've also owned the other "reference monitoring headphone", the Sony MDR V6. Dunlavy tells me this tonally accurate headphone you can trust to monitor sound. Why don't I like it then? What is useful as a monitoring tool does not mean it's enjoyable for music listening.
True. I have reproduced the same experiment presented by
[3]Dunlavy, and found the results to be as he claimed. But I do not care for this headphone, personally, for music enjoyment purposes.
