That's about right, though there's no definite rule for burn-in. Read Head-Fi: Headphone 'Burn In' FAQ to get what I mean.

@nymerine

Not so good actually because will weaken your driver really fast. All electronic stuff have MBTF (mean time before failure), the longer you use, the fast it's will fail. I also sleep with headphone on my head from time to time but I only set playlist maybe for 1 or 2 album.

i just use my daily listen music and play it......

though some say use those pink noise, white noise etc....

Hehe nymerine, just clamp ur headphone onto the top of your casing for an hour or two. Sure comfortable already. If not, clamp for another hour or two.

Or you can just constantly stretching it.

I usually would just let it burn in by listening to music normally unless you cant wait for the full potential.

And about the failure, you probably upgraded it long before it dies. XD
