Got the grades in my book, buttt
But I found that the building cost behind these things only cost the diaphragms from what my eyes detect.
No, I was never one to actually "feel" or HEAR a Sennheiser sound signature... or any sort of Brand iD'd co. ie; ATH, AKG, Sony, aiaiai, etc., for this matter.
If you put these headphones on me with my hands tied behind me back, I'd say they are honest, and visually flat--this makes producing with an Apollo Twin MK II literally gold for electronic music.
its an honest sound profile that can detect spaces and environment of an audio transient, when you can afford the necessary Ohm Impedance ratings for a pre-amplifer/signal-chain to make it happen lol
So I'm siding with the crowd on this being flimsy and exquisite to put it nicely; but then again, flashback to what I was saying, if I went blind and lose my senses, and all I can do is hear, I hear quality.
If build quality is like having no oxygen for you, then maybe Silicon/Matte fibers (that also does weigh alot more than what people carelessly define as toy plastic materials) casings and headband are the decals you need.
It would cost both Sennheiser AND Mass a whole lot more to invest into a more stronger and ergonomic design; So What Will It be kids?
these headphones @ $220? or go full PioneerDJ, and just say it passes one (MIL) shock test and charge ya an extra $150 for a heavier set? I'll stand happy right now at $220 :)
Would recommend to a friend.
