Please don't "explain" headphones to me. I've worn them for many hours a day for 35+ years IN MY WORK (as a radio personality, producer, and now studio owner and host of an internationally syndicated show called "Saving the 70s"
Saving the 70s That's me on the site, wearing a pair of Sennheiser HD-451s, one of the MANY pairs of headphones I own. If you've read my previous posts, I have discussed some of them, but they include the Sennheiser HD-600, the HD-580, the HD-451, HD-40, HD-400, the PX-100, the Sony MDR-V6, AND the MDR-7506 (I know they're the same 'phone!), the Beyerdynamic HD-990 pro, Koss Porta-Pro, Koss KSC-35, Koss KSC-75, Koss A-130, Koss A-200, Koss Pro-4AA, Koss HV-1A, Grado SR-60 and SR-80, and many others. I'm a headphone junkie...using them not just for pleasure, but as a tool IN MY WORK.
So perhaps I'm better qualified than most hear to question YOUR ability to determine "sound quality" and "value".
I've stated MANY TIMES that the Bose OE 'phones have elevated bass...but they also have VERY extended deep bass, which most 'phones DO NOT. GREAT open-air 'phones like the Grados and Sennheisers raved about here usually fall-off in response quite steeply in the bottom octave. Play a 30hz, then a 20hz tone through the Bose OE, then play the same tone through the Sennheiser HD600, and you'll quickly appreciate that the Bose is FAR MORE SOLID, and reproduces FAR MORE FUNDAMENTAL at these extremely low frequencies than the Sennheisers (or Grados), for instance.
Your assertion that Bose OE headphones have "no highs" is laughable. The highs are ALSO elevated somewhat, as is the bass. I would have had more respect for your condascending attitude if you'd complained the Bose 'phones have a "smiley-face" eq curve, emphasizing bass AND treble. They do just a bit. Again, no 'phones are perfectly linear. Not only that, since our ears are shaped differently, the same 'phones will likely sound different in the midrange and highs to you than to me. Sound quality and value ARE SUBJECTIVE!
I don't use the Bose 'phones in my studio, because I don't think they're rugged enough to stand up to such heavy-duty use. But I DO think they'd work quite well for mixing. The elevated bass would keep me from dialing in too much bass, and the elevated highs would prevent me equalizing in too much high frequency "sizzle", as we hear in far too many modern recordings.
There are many things about which you may lecture me, but I doubt I have very much to "learn" about headphones from most here. I've worn them for hours dach day since Nixon was president. And unlike most here, I have been, and AM PAID FOR IT!
