Are there any ways to open the driver safely without damaging the hings?
how's that going?
Can anyone tell me the exact diameter of the round part that houses the driver? I mean the one pictured in the post above. The entire thing, should be something like 80-95 mm, I need the exact number. I've got DT770s with dead drivers, I was thinking of buying this Philips and making a frankenphone if it fits.
You mean like buying the SHL3300 specifically for it's drivers, and transferring those drivers into the Beyerdynamic cups
I have an even better idea! Instead of going to all the trouble of starting a new thread, why don't you just add it to the Mods thread?I figured that the SHL3300 baffles would be too large for Beyer cups (their opening is 85 mm and the SHL3300 baffle looked like it would be a bit more than 90 mm) and bought the smaller and uglier SHL3200 instead. These are a perfect fit, I've already transplanted them. I'll add pics later, or start a separate thread on that project and add a link. The results are surprisingly good - the headphones are a bit brighter than original DT770s (that I also have - 32 ohm and 80 ohm versions) but sound really good. Plus, they have the Beyerdynamic comfort, sturdiness and looks, but unlike the Beyers they can be easily powered by pretty much anything. And the total cost of Philips SHL3200 + Beyerdynamic 770 with blown drivers + COP pads was $40. Plus I did the humanity a service by disposing of the world's ugliest headphones
If I manage to get another SHL3200 so cheap ($17 brand new) I will try do do the same thing with DT990 cups that I also have, see how they behave in an open back scenario. In any case, both SHL3300 and SHL3200 are definitely worth buying for drivers alone.
I ended up buying SHL3300 too out of curiosity. They look much better and are more comfortable than the SHL3200, which are an atrocity in both respects. SHL3300 are not terrible even with stock pads, much better with Custom One Pro pads I had lying around and could not use on any Beyerdynamic DT headphones because the sound was bad. COP pads actually emphasize the treble a bit, so I haven't removed the grille yet. I will try with grilles out and with DT770 and DT880 velour pads later, see which version sounds best.
Of course you're welcome to do both.I can do both. Separate thread is easier to find (I'm thinking mainly of owners of DT770s with blown drivers, and judging by the number of these on auctions there might be quite a few). Plus, I have more experiments with Beyerdynamic cups and various Philips drivers planned. Philips has been making excellent and cheap drivers for a few years now, and Beyerdynamic cups and headbands are awesome in terms of comfort, durability and looks (for me at least). So a thread makes sense.
I have the SE305...they have these massive cups that are covered in pleather...some versions came with multiple drivers also...the point is it's a very versatile chassis, I already did one transplant as a test, but the drivers have a weird sizzle to them that I know is just proof of their lack of quality. (so, not worth trying to fix, just ditch and move on) I am curious to see if they sounded so good because of the original drivers or the cups...I actually have vintage Pioneers SE-50 (got 2 of those, one working and one I got for parts and could go crazy with), but adapting those for such a mod would be tricky. They have 2 drivers, a 3" paper cone "woofer" and a small FF driver in front of it. So there's no baffle in the Pioneers that I can work with and I don't think the baffle from 3300 can be adapted for this cup. But I'll have a look when I have time to dig out these Pioneers.
