for me is a non sense , is like having a dolby 5.1 surround home theather without the subwoofer , so i dont understand why a headphone like hd800 is considered an audiofile when something is missing in the sound ( 'sub bass' in this case) . If the bass is missing is OK a great phone but if the mids and highs is lacking , OH NO is garbage !!! For me a audiofile headphone must deliver ALL the sound freq flawless, what do u think ?? thanks.
A - Because "deep and strong bass" usually means that headphones are not balanced; in other words the three frequency bands, the bass, the middle frequencies and the treble are not in line in volume. If the bass is 'out of whack' and floods the middle frequencies, that means if it interferes with the vocals or with the sound of instruments then headphones with this kind of sound signature do not have natural balanced sound and thus they are not 'audiophile headphones'.
B - Generally, headphones with a moderate bass boost, relative to the vocal and instrument range part of the frequency spectrum, up to 5-6 dB [deciBel], are still considered 'balanced' and regarded as 'audiophile' headphones. From my experience headphones like HD800 or T1 have decent enough bass end [T1 a bit better than HD800] but their bass could be stronger and they would still be of 'audiophile' grade.
C - Somewhat illogically some headphones with a relatively weak bass are still considered to be of 'audiophile' quality.
D - The major problem is that the electrodynamic headphones [at least 95% of all headphones sold] cannot equally present, in the same volume, all three frequency bands; the driver and its diaphragm of the electrodynamics cannot produce clean, and of the same power, electroacoustic waves uniformly from down in the bass up through the middle frequencies and into the treble. Compromises have to be made, something has to give. They are of three kinds which makes for three sound designs :
1 - Rolled off [weak] bass and good 'mids' and decent treble
2 - Rolled off treble and good 'mids' and good bass
3 - Good bass and decent treble and 'rolled off' [recessed] part of the middle frequencies, which means that vocals sound fainter than they should - unbearable when one listens to vocal oriented music.
But, at the very, and expensive, top of the electrodynamic headphones pyramid one can find a very few 'Top of the Line' cans that manage to play all three frequency bands pretty evenly. Three of them are currently in production.
E - What is one to do when deciding to buy good headphones ? My view and advice is to buy headphones that present middle frequencies and treble correctly, the middle frequencies are the most important because that's where the music lies. The bass can be taken care of by simply using the bass knob on an amplifier, or doing bass 'EQing' on portable player. It is relatively easy to boost bass but it is more difficult to create good treble with a treble knob. The most importantly, it is impossible to 'boost' middle frequencies, they spread too wide.
F - Many people buy 'planar magnetic' headphones, which use different technology to produce sound, because these headphones present more prominent bass. The big caveat is that there are no perfect headphones and the planar magnetics have their own problems, specific to the technology used. They have more bass but they generally suffer from treble anemia. The second problem is the sound produced by the planar magnetics is less dynamic than the sound produced by the electrodynamic headphones, the bass of planars has more quantity and better extension to sub-bass but it does not have enough 'thump' [impact] compared to bass of the electrodynamics. My view is that the top few of the electrodynamics, three in production and two out of production, present the best sound signatures when one wants to hear the correct compromise between the bass quality and the balanced presentation of frequency bands. When you turn the bass knob when listening to electrodynamic headphones, you get enough bass volume and bass thump; with the planar magnetics the bass knob will not make bass more impactful.
I left out the electro-static headphones, they are a different world.
