    @Chris Cables I can't see your googleusercontent images they may be set to private :confused: Could you mirror them somewhere like imgur and replace the images in your post?

    You should be able to see them.
    Nobody else see them?

    I can, so it can't be a "private" setting.

    Okay seems to be a case to case thing, then. But yes at least some of us can't see. Weird~

    Okay, well, if it's any consolation now I can't see my own photos either!
    Is linking to a Google photos account not allowed here?

    I'll see what I can do later but at the moment I'm up to my eyeballs in cable-builds and out of my skull on solder fumes... lol

    For photos I want to post here, I upload them to https://imgbb.com/ Then paste the image url to the image upload feature here (the little mountain icon).

    Couldn't see a way to edit the original post so here it is again repeated, apologies, but with imgbb and imgur links. Hope it works!
    Thx for that tip @ColtMrFire.



    Longtime lurker to this forum, so I decided to sign up specifically to make a contribution to this thread...and to become a bit more active on the forum of course! So, a 'hi' from me and hopefully a worthwhile introductory post...

    Really wonderful to see so much enthusiasm for these Sennheiser models and my admiration for the HD650 in stock form is absolute. In my opinion it is and will always be an alltime classic, along with it's sibling the HD600 as well as the entire HD series going back to the 'Made in Ireland' period.

    My journey began back around '95-'96 with the purchase of a lovely HD565 set. My first 'proper' headphones and those cans served me well until about 5 years later when I started to get intermittency in the left channel and the foams had also started to wither and die.
    'What a shame' I thought as I consigned them to a drawer to be forgotten about until a few years later when I was having a clear-out as part of a house-move and decided if I could refurbish them.

    To my surprise after contacting Sennheiser UK directly, I was informed that all the necessary parts were available to purchase as user-serviceable parts and it may even be advantageous to replace the driver capsules with ones for the HD600 or HD650! Wow. 'Ok, I'll take some 650 drivers, some earpads and a headband and a new cable please!
    Parts received I set about refurbing them. On completion, I was immensely happy with the result and this started a 25 year and ongoing obsession with the Sennheiser HD*** series.

    In the collection now are totally refurbished/functioning sets including the HD265, HD525, HD535, HD545, HD565 (x7!), HD600 and HD650.
    I also have 2x HD565 chassis re-drivered with new HD600 and HD650 drivers respectively. 'The Frankenheisers!' as I refer to them :D

    I recently purchased a Tascam MH-8 and built 8 identical SE cables in order to compare all the models side by side which was super interesting!
    The plan is to compare my original (SS) HD600 and HD650's with the HD565-600 and HD565-650 Frankenheisers but after recently commercialising my hobby into a full-blown business 'Chris Cables' I'm currently short on time with a huge backlog of orders. So it will have to go on the backburner for now.
    I can already attest to the fact that HD650 drivers in a HD565 chassis DO sound different and I assume this is due to the partially obscured outer baffle of the chassis driver nacelle. There are also a couple of voids in the nacelle for each driver which can be 'tuned' with different sizes and densities of foam, which also yields interesting results.

    In any case, I intend to explore and experiment further using the HD565 chassis and different driver configurations in the future. Lots of fun!

    I posted about my collection on head-fi in the HD565 appreciation thread but thought it may be appropriate or interesting for some to read about here.


    The current line-up. Plus, there are another 4 pairs of HD565's not included in the photo!

    The Tascam MH-8 has been a worthwhile investment in order to compare various models

    Fun with the HD265. HD650 drivers in the closed-back environment of the HD265 nacelle is .....interesting.

    Update@24/4/23
    There may be another 2 pairs of HD565's entering the stable, which would bring the total to a ridiculous 9 pairs in the collection including the two HD565 Frankenheisers above :eek:

    Hehe.
    That's only the Senns too! There's a whole load more lurking around here including AKG's, old Pioneers, Audio Technicas, Sonys, etc.
    I'm no Zeos Pantera but you're right; nobody needs that many headphones!
    I feel more like I'm 'curating' these old Sennheiser Ireland-period sets though and in that respect it feels worthwhile. It's also interesting to see how the range has evolved and what distinguishes each model. The HD535 for example are a complete sonic trainwreck to my ears, while the lowly HD525 sounds epic in comparison. Go figure.
    Others keep banging on at me to complete the line-up with a HD580 and they're correct of course. So it might happen one day....

    Is there difference between the drivers on the black screen 650’s and modern ones?

    The black screen hd650 is darker and having better dynamic swing to my ears compared to the hd6xx . The 6xx is a little more detailed imo
    I don’t think I can distinguish them via a short AB comparison

    Yes that’s the difference in sound of the whole headphone, but I was asking if there were any differences with the driver itself, outside of normal unit variety

    Okay so I removed the silver mesh from my 650’s. I get a good amount less bass and less lower mids, detail is more apparent.

    Next up I’m gonna put a couple of layers of micropore tape in it’s place, hopefully this will get it as close as possible to the original black paper screen version

    Micropore isn't a good permanent solution as the adhesive breaks down over time and turns into goop. You then have to clean it off and reapply it.

    Not sure where to put this and I’m sure someone has done this before… but the stock foam with the notch in the middle was giving me some annoyance after a while. Maybe because it’s relatively new and needs to soften up a bit or this has had a change like the newer pads which are firmer.

    In any case i decided to make a suspension strap out of an old leather belt and figured id share the measurements in case anyone wants to make one of their own.
    So you need to cut the belt/leather strap to a length of 22cm, then at 7mm distance from the edge you make slit where the metal part of the headband fits through. This has to be a width of 25mm and of course you have to make sure to use an adequate strap, the belt i used is 45mm which is ample for comfort and strength.

    Installation is simple: pop out the plastic clip at the end of the headband and slide out the pad and then the metal part of the headband(lift the small metal bit used for indentation to fully remove it). Put it through the slit of the strap and reverse the steps sans padding to put the headband back together. Do the same for the other side and you’re done.

    This leaves about 10mm of space between the strap and headband which is similar to a fresh set of padding.
