Headphone/Speaker Burn-in....discuss

[arun1uk]

Just got a new pair of B&W C5 Series 2's, as my Series 1's were replaced under warranty.
Was speaking with a friend who mentioned I should "burn them in". Whilst I appreciate the rationale, has anyone actually noticed a difference, either way?

Is it worthwhile or a waste of time?

Discuss, show your working.

But what about headphones - will it make a difference? How will it be different from me just listening to them on a daily basis?

Thanks fellas, appreciate the advice.
So far have changed the tips for Comply Foam and have left running for a few days with pink noise track playing.
Sounding nice and warm now but still some way to go.

It depends on the earphone/IEM, dynamic driver earphones can and do change, balanced armature ones generally do not change, although some insist they do.

They've definitely changed. Bass is deeper and highs are brighter. The reason I know this is because comply tips are constant, I've been listening to the same track (regularly) and can identify the lows that I'm used in my old pair of C5s.

Appreciate your opinion, though.
