Just out of curiosity, have any HD820 owners noticed condensation build up on the inside of the glass after a listening session?

Mine appear to steam up slightly only after an hour or so listening.

It doesn't take long for it to evaporate / clear, but it's something I've only just noticed.

In theory I guess this is probably quite natural , cool room with body heat from having the cups over your ears would cause condensation on glass.

Anyone else?

Thanks!

Theres a leak with your glass? wow, that sucks.... I would send it in right away...

It would be interesting to see if anyone else has experienced this and whether it's just a natural thing to expect.
I would describe it as the exact same affect of getting in your car and the windows fogging slightly.

I honestly don't believe it's a fault - just a natural affect of glass steaming up when warm on one side and cooler outside?
I may reach out to Sennheiser for comment.

If I get the opportunity I will share some pictures next time I try them.

if thats the case, wouldnt it happen outside of the headphone and not inside? I would imagine if condensation built up inside of the glass, that means water can form and damage the driver, although thats really extreme, but weird stuff happens.

Hmmm, you make a good point.
I've dropped a support ticket to Sennheiser so I will share any feedback. Hope to put up a picture on my next post.
Thanks.

it makes sense that condensation would build up inside, if the outside temp is diff than the inside of the cup. Im sure it happens with non-transparent closed backs as well

you just cant see it so you dont know and dont worry about it. I would take steps to let it dry out and minimize/eliminate the condensation

I would honestly just contact Sennheiser, it doesnt hurt and it doesnt prevent them from denying your warranty due to negligence.

Let us know too, I'm curious, I never seen it but may happen in the future.

I live in Hawaii. Mine did that recently on a crazy rainy day. Not worried about it at all.

I went scuba diving with mine last week, same result.

You could leave them in a closed case with some silica to dry them out

does rice work? lol....

I've dropped Sennheiser a support ticket. Hope to hear back from them after the Easter break. I will post their response.

Appreciate all the feedback from everyone!

Who knows, maybe you should try lol

Just don't get it inside the headphones, or else you may get an flowery natural soundstage from them.

For serious though, some bags of silica and the headphones in a closed case will solve this kind of issues

I get a silica packet every time I get beef jerky. Guess its a good reason to buy more jerky, to dry my headphones!

Just following up with a picture.
As you can see there is condensation build up on interior of the glass. I'm still waiting a response from Sennheiser (but it has been a holiday weekend).

I'm suspecting that this is normal and probably affects all closed back headphones in some shape or form, but due to glass being used in it's design, it's just more obvious.

I will say that since the weather has changed over the weekend and it's warmed up considerably, I've not had any condensation build up (when listening).

This is leading me to believe it's a combination of climate/atmospheric conditions (very cold last week) and / or excessive moisture in the air at the time when I've been listening .
I'll run some further tests in my listening room with a dehumidifier later.

(Quick Edit) - It took about 10 to 15 mins for the glass to clear.

UPDATE - Issue is resolved (environment condition) - https://www.head-fi.org/threads/sennheiser-hd820.846244/page-175#post-14916032

Likely with other closed back headphones, we just can't see the condensation build up so out of sight and out of mind.

It is dry over here in LA, so I never noticed any condensation build up in the HD820.
