I think you are correct. Thanks
Thanks for the info, just checked my and it has it.
Yeah, my 2010 silver drivers don't have it.
I can't help but imagine the guys at sennheiser looking at each other laughing and saying something like: "ok what do we do for the next 6 month to drive the guys on headfi crazy over nothing? I suggest a pikachu printed under the driver. and next year we'll start putting the 4 spots R on the right side for braille instead of the 3 for L. arhhh arrhhh arhh it's good to laugh!"
Hello all, just thought I'd share my impressions on my experiences with the Senn. HD 600 and the 650 recently.
I received the HD 600 brand new about 10 days ago. Initially I thought they were excellent at detail retrieval with highs, yet significantly too bright overall. So then began the burning in process, hoping to flatten out the frequency response to some extent. But after a total of about 150 hours burning them in (with a sort of pulsating pink noise at moderately loud volume), they appeared to still sound the same - perhaps the only difference was the 3D sound imaging may have improved a bit (or it may have just been my perception). After extensive testing compared to other TOTL headphones such as Beyer. DT 880 32-ohm, Soundmagic HP 100, etc. here are my conclusions on this pair: Excellent detail retrieval in the highs and 3D imaging, but that's as far as the compliments go. The bass extends impressively deep but was SEVERELY lacking in volume - even using EQ to boost the bass frequencies several decibels below around 200hz still didn't allow these headphones to put out as much bass as my other headphones, which have a fairly flat F.R... almost as if this thing was completely incapable of outputting proper bass. The midrange and the whole hi-end of the frequencies were exaggerated in a way that changed the entire tonal character of all sounds so that it seemed everything was at least 1/2 octave higher pitch than is natural. The higher frequencies were so overblown that listener fatigue came around every 15 minutes.
So I ordered the HD 650 (brand new also), knowing it has a reputation for more bass impact.
Right out of the box I immed. heard what I consider to be a correct amount of bass. The treble seemed slightly veiled and the midrange was just about pitch perfect. The bass seemed to be just the right amount - right in between the amount of the Beyer. DT 880 and the HP 100 - a very pleasing bass, but seemingly not quite a deep as on the HD 600, and as if it's slightly congested / boomy (hopefully more burn in will help that). While the highs and mids were more laid back or veiled than the HD 600, it seemed quite pleasing for a more natural FR and less listener fatigue. The 3D holographic imagining is amazing, albeit slightly less than on the HD 600 (I suspect that too may be something that can improve with burn in). Then onto the weird way the HD 650's are playing vocals and talking voices. On one hand, voices sound quite well textured and fun to listen to - but on the other hand I get a faint feeling of un-natural-ness as if you're not there, and there is this sort-of grainy texture issue in the upper-mids to highs, where each crackle of the person's voice seems somewhat more than in real life.
I have been running this all through my Magni amp connected to an amplified soundcard of my laptop, and playing both lossless and lossy files upconverted to 96khz / 24bit - various genres. I suspect however that the certain grainy-ness in the upper-mid to high frequencies which I have heard through both headphones could be the result of the sub-par DAC in my soundcard, so hopefully the TOTL soundcard which I have on order will improve this issue.
A strange thing is that I have already compared several other HD 600 & HD 650s before at a headphone meet, and at the time I couldn't hear any difference besides a a difference in volume (it wasn't a genuine A/B comparison though because one was on a louder balanced connection while the other was standard SE connection). Those cans were burned in quite a lot more than mine, so I'm wondering if the 600's will increase in bass quantity and have a more relaxed treble after long burn in; and if the bass of the 650's will become deeper & less boomy / congested with more burn in - as well as hopefully an even greater 3D soundstage. Or this could just be another case of manufacturing inconsistency - a fluke in the industry which I have noticed several times with other headphones - in which two headphones of the same model produce different sound signatures.
All being said, the HD 650's are rapidly becoming my prized posession! Fluidic, warm sound signature, open 3D holographic imaging with great depth perception and pleasing with any genre I threw at it, from rock to electronica and everything in between. These could even be the 2nd best headphone I have heard after the Hifiman HE-6 and HE-1000! I am though, about to return my HD 600's. I'm just hoping these 650s can really shine with a better source chain and break in time. Let me know your comments on my impressions, thanks!
PS- it was very interesting to notice how both the HD 600 and 650 can produce such a different soundstage, although the only physical difference I could tell from the outside (besides color) was the foam damping material seemed slightly thicker on the 650.
