Hi, I once took possession of a pair of second hand akg 702, which the owner said had 100 hours of burn in. I'm no audiophile even now, but when I eagerly greeted the postman unwrapped the package and put the phones on, I was livid as I could easily hear distorted hi frequencies. I thought and hoped that this was down to a lack of burn in that they talk about on audio sites. So I left them on for 12 hours and when I checked later the distortion was gone. Obviously this was not a case of burn in, but I didn't realise at the time. It was months later when I learned that when you take delivery of new HP's you should put them in your airing cupboard so that they come up to room temperature. Being out in a van which is not heated and maybe coming from big depots and/or on cargo ships, planes etc, if they're imported, they are going to be cold and not perform at their best. This I believe accounts for SOME instances of alleged burn in, so how many of you guys have shared this experience?

This is good info, never would have thought about that.

I believe in burn in. I don’t think it makes huge differences but I notice small changes and they are always consistent with my ears. I think it’s more mechanical like drivers loosening up. But I consistently hear a small drop in treble and a small increase in bass over time with headphones. I have, however, never heard the opposite. To each their own.

What do you think of the burn-in apps? For example, there are "Moshi Burn-in Tool" or "Burn in Lab" or "JLab Audio Burn-in Tool"?
Is it possible to worsen the headphones by burning in with "bad" frequencies?
Unfortunately I can not order the "Ayre disc" as Ayre only delivers within the States.

These almost like Portapros, with a few significant differences. I need a pair to add to my Hot Wheels collection!! Safety first!
