    Hi,

    I'm thinking of getting these for my vintage TASCAM 244. I'm just wondering
    if my 244's headphone amp will be able to "drive" these alright ? The 4AA's
    are 250 ohm and have a sensitivity of 95 db. I have a problem, though, with
    my 600 ohm AKG's which have 88 db sunsitivity. These have a problem getting
    loud enough. Will the 4AA's, based on their specs, be better in this regard
    ?

    Thanks a bunch,

    Daniel

    One more question I meant to ask: What is the difference between the still
    manufactured KOSS 4AA's and the ones introduced 30 years ago ? Are these
    still the SAME headphones ?

    Thanks again,

    Daniel

    Yeah, vintage phones for a vintage format.

    <<I'm just wondering

    Yes. The real question is how long you think you can withstand excruciating
    pain.

    << Will the 4AA's, based on their specs, be better in this regard?>>

    Yes, no. Since the Pro4AAs are based on a medieval torture device designed to
    squeeze your head to within an inch of your life, whether they sound better
    than your AKGs is a moot point.

    uncomfortable after a while.

    The originals were made in the States. The current model is made in China. Saw
    some when visiting an Oritron factory. Don't know how good they are compared to
    the originals. I asked our contact if there was any chance of a freebie but had
    no luck.

    Can they be any worse than the originals?

    You could just get a pair of over-the-ear Sony headphones, then put a big
    C-clamp on your head and crank it down until your skull starts to crack,
    then hang a cinderblock off each ear. The effect will be similar.

    Those made even the older Grados seem comfortable in comparison.

    ---------------------------------------------------------------

    Scott Dorsey is right elsewhere: comfortable, the Pro4AA's ain't. I bought
    a pair of the "Anniversary" models that came out a few years ago, just for
    nostalgia's sake, since I had owned a pair in the early 1970s when I was in
    college.

    They're very heavy compared to modern 'phones, and the vice-like grip is
    definitely not comfortable over time. I use them only when they're all I can
    find, and I'm in a big hurry.

    I'd recommend any of the better Sennheisers as being more accurate and more
    comfortable, but the popular 580's and 600's are a little difficult to drive.
    You can't get a lot of level out of, say, a Walkman-type player, but any
    regular component like your Tascam mixer should have no problem.

    True, an uncontrolled desire for prostitutes, pornography, and phone sex is a
    terrible thing.

    It depends. I use the 580s with a Sony Discman, and they're loud enough for
    anything short of trying to blow out your brains with Wagner.

    Ditto.

    I hear all these comments about 580's not getting loud enough with
    portables, and I really just don't get it. I'm 58 so it would appear that I
    don't have the most sensitive hearing in the world. In fact many people say
    I like my music played way too loud.

    I like my 580s with every player I've tried including a Nomad 2 that runs
    off just one AA battery. In the latter case 580's don't fix what's wrong
    with MP3s, but that's a totally different story.

    Admittedly 580s don't bite the ears like 7506s and the like, but...

    Anybody know if the sensitivity of the 580's improved over the years?
  12. > Anybody know if the sensitivity of the 580's improved over the years?

    They might have, but mine are at least seven years old.

    They are more subtle than that, modern day psychological torture was built
    in too. I tried on a pair that I have had in a drawer for 30 years and
    found that the soft plastic had decomposed squirting the fluid in my ears
    and all over my hair.
    Some of you guys must have some pretty big heads, I never used to find they
    squeezeed (maybe I've got a small head), but the weight of them used to
    give me neck ache after a short period of use.

    It has been a constant 300 ohms & 97 dB SPL
    from inception.
  15. Hmmm...

    There's something about Koss Pro 4AAs...

    After all this dislike, hear from a diehard 4AA user.

    They are heavy, but not uncomfortable if you fit them correctly. The
    earpad goes around, not on, the ears and seals tightly on my 7 1/2 head
    size without a viselike grip to give as good isolation as I've heard on any
    other headphones (having never tried the gun-range-style mufflers). The
    sound is brighter than speakers, but clean up as high as I can hear.

    All my 4AA's are around 30 years old.

    Up points:

    The sound of a headphone or speaker is a very personal thing. I like my
    4AA's best of all I've ever heard. I also like high end Beyer headphones.
    I don't like any other AKG's or anything from Sony for critical listening.
    That's no reflection on those companies, just my personal taste. I think
    its the size of the cavity inside the headphones. It's small on the 4AA's
    and larger on most others closed cans.

    Downpoints:

    Don't wear glasses. The temple pieces will press against your head and
    hurt after a while. They also break the seal.

    Set the height just right. Required to make them fit properly behind the
    ears and not feel extra heavy.

    Short cord. The coiled cord is only about 4' long coiled. As I hate
    "semi-coiled" cords, I always use an extension cord, even when working
    right at the recorder.

    They require regular rewiring with heavy use, as I think all headphones do.
    I seem to always lose just the right channel.

    I would like to add something to this thread ... I don't know why people get
    all exited by all the light, plastic, "junk", as I like to refer to it,
    today. Today's headphones might have the "latest technology" built in but
    most feel cheap and flimsy and most don't even go over the ear but rather
    on. The 4aa's have been around for 30 years and withstood the test of time
    because they're damn good headphones.

    Funny, I was using a Hilti gun only last week and the industrial ear
    protectors hardly felt like I was wearing them - they worked though.

    Despite the one unusual experience, I didn't want to give the impression
    that I didn't like them. That's why I've kept two pairs for 30+ years, but
    I tend to use DT150s mainly now.

    Depends on the frame design. I wear glasses now and have not found that to
    be a problem.
  19. Did you actually make a power tool joke? <g> I believe that's a first.

  20. Ah, glasses. Now there's another reason to pay attention when buying
    headphones. Who thinks of it? Particularly if you only need glasses for
    reading. I would never think to take my glasses with me to test drive
    headphones, but there it is.

    Good point, Carey. I am constantly wearing glasses when I have cans on.
