    Default Good, cheap headphones - Koss Porta Pro

    Just a quick heads-up for those looking for some nice headphones for just a couple of £10 notes.



    I just wanted something half-decent to plug easily into my laptop for sampling tunes off Amazon prior to purchase and casual listening while perusing AOS.

    At a touch over £20 these provide good clarity, definition and high end extension with no harshness, nicely projected and neutral vocals and a pretty decently defined and deep, if slightly tubby bass.

    Really quite cumfy, too.

    For £20 or so these seem a bargain to me.

    You seem to have four very weirdly shaped ears Jerry

    Nope, usual shape and number, although they are of course Golden.

    -- the extra spongey bits help with the comfort, I think, by relieving pressure on the ears. They do seem to work well.

    Looks like something Joe 90 would've used!

    Anyway, glad they're hitting the spot, dude. Koss headphones are great - I wouldn't swap my PRO4AAs for any supposedly 'superior' high-end designs!

    Yep, they are a bit retro!
    And all the better for that, I reckon.

    -- I seem to remember those Koss PRO4AA - mahoosive beasts, I don't think my neck muscles are strong enough.

    We've been here before, but aren't the current Pro4AA's updated internally over the 1970's models? When I went to look, the bargain priced new ones had long gone, so I went with what I knew and found some Sennheiser HD265's, which are broadly similar sonically to the Sony's 'everyone' was raving about here a few months ago (I haven't done a direct comparison though, but had a good listen to Alex's set a month or two ago - they're nice)

    Ah, I see... If that's what Andre's on about, then it doesn't matter to me, as I've compared the current models to the originals, and sonically, which is all I'm interested in, I much preferred the current ones. Andre's entitled to have an alternative opinion, and that's fairy muff!

    I would not buy the new ones because they simply are not an original production model from back then, however i do have an original 1970's pair & i don't like them.
