Terrible choice for a busy office unless you are WFH.
They are absolutely open backed.

Well, I’ve used them at the office with my door closed and they were fine. At least I could still hear my phone ring.
They wouldn’t be a good choice in a cubical or shared space.
Something I've noticed with my HD650s is that, quite a bit more than other headphones I've had, they need to be cleaned. Debris gets in somehow, really small stuff, and then rattles against the driver whenever there's bass/drums. This problem can, of course, happen to every headphone. But this one... I'm finally annoyed. It took a few years, but it happened. Normally I wouldn't care, except for It makes me feel like I'm going to damage something with every procedure. I don't know if each time is weakening things, or... Yeah.
I'm annoyed lol.
Has anyone else noticed this?
I still highly recommend this headphone - its frequency response is perfect with minimal equalization. Imaging could be better, but, hey, you can't have everything unless you're willing to spend a lot a lot a lot. And I'm not! lol

Yes indeed, had some mysterious rattles with mine over the years. Turned out to be pet fur near the drivers!!

If you go to google and search "online tone generator" you'll find this site...
or click { http://www.szynalski.com/tone-generator } (idk if my typing the link will work, might have to Ctrl + C then Ctrl + V it - or search it like above, it's usually second, but sometimes first or third)
From here, make sure your computer volume is down to like 10/100, then adjust the 50% level in the website to 98% (100 can slightly distort on some machines) and also drag the slider down to 25Hz. Press play.
25Hz is low enough that you can barely hear it for how loud it actually is, and gets the driver moving enough for you to hear the rattling. The volume should be pretty low, so gradually increase the computer volume from 10. You should start hearing the rattling between 20 and 35. I don't know your system or its voltage output or the 580s sensitivity vs the 650s, but with a 4.0V RMS output, my 650s can have 98% in the orange window and 100% on the system (giving like 3.95V RMS on the output), and it's not until the frequency drops to 21Hz that the drivers begin to bottom out. Bottoming out at these low frequencies will sound like a tick with every time the back of the voice coil hits the plate. If you're gradually approaching a lower frequency (one at a time) or increasing the volume one at a time until you pass xMech (mechanical maximum), you're guaranteed not going to damage your driver. It'll be the softest tap, and since these are high quality drivers, you should definitely know that's what's happening when it happens, even though it's really quiet. If you do discover you have a lot of noise from dust/debris, I'd recommend doing your best to remove that first so that you can be as safe as possible!!
I've had a couple of my own shorter hairs get it from the side of my head lol. I don't have any pets (though a cat would be nice...). With really low frequencies, the hairs sound like they actually scratch against the drivers as they move back and forth!
Hairs can actually be pretty sharp... I wonder if one was held as an angle somehow, through the foam maybe, with the end of the hair poking against the exact same segment of the driver as it moved back and forth, if eventually, the hair would cut through the driver? And then as time progressed, if that cut could widen, getting longer and longer, until it crossed the part of the driver that was originally cut? That'd suck!
How long have you had your cans? And about how many times would you say you've taken them apart for cleaning?

Sure, I've tested them to the point where they bottom out - gradually, gently to avoid damage. I've just not seen that caused by debris, nor have I ever bottomed them out during listening. Maybe I just don't crank them up loud enough.
You should try again in the 20-30Hz range, maybe get the driver moving 1/4 to 1/2 xMech to see if you hear any extra buzzing.
It really doesn't need to be very loud at all for buzzing to become audible from debris, maybe 1/2 to 2/3 the level of what it'd take to pretty much drown out road noise in a car. Or about 2-2.5x louder than the typical TV and it becomes apparent. I don't usually listen to bass heavy music either. Depending on the debris rattling, it can be obnoxious and once you've identified it in a quiet part of a song with bass, it's obvious after lol

Which of these dac/amplifiers can run the HD650 at full potential and would match the best?
Does the Fosi K7 do not have enough power for the HD650?
- TOPPING DX5 II Dual ESS9039Q2M 300€ 6.4W
- FiiO K13 R2R 319€ 1.2W 2.4W
- FiiO K7 AK4493SEQ 230€ 1.2W 2W
- Fosi ZH3 AKM4493SEQ 200€ 0.65W 2.6W
- Fosi Audio K7 AKM4493SEQ 200€ 0.6W 2.1W

They all have plenty of power.

FiiO K7: L+R≥560mW+560mW（300Ω / THD+N＜1%)
This will make your HD650 reach 125dB SPL peak.... per ear ! (the HD650 is rated at 500mW max)
Fosi K7: 250mW in 300Ω (balanced out)
This will make your HD650 reach 121dB SPL peak.... per ear !
Fosi K7: 65mW in 300Ω (TRS out)
This will make your HD650 reach 115dB SPL peak.... per ear !

I've just replaced my band and pads on my (2006?) 650s.
I'm impressed with how these are built and are designed for easy repair.
They are such an easy headphone to live with which i think gets lost in the hobbys urge for micro-improvements.
I can listen to these all day and throw them around without babying them.

They're tanks, yeah, but do be careful with physical impacts as their voicecoils aren't soldered, they're just tightly intertwined with some springs that connect them to the cable sockets, so physical shocks can displace them.
Once that happens, you have to open the whole assembly, take out the driver and resit the spring with a plier while being careful not to tear the coil. Trust me, it's better to be preventive

Do they have a audiphile spring upgrade kit?

Unfortunately they're already gold plated, so if you want to upgrade the HD650 sound you must look elsewhere. Maybe try an overpriced tube amp so that their mids will open up more? /sWhat audiophile grade cleaner do you recommend for these contacts?

(if you're not being sarcastic: don't worry about them, leaving them be is best).
