Headphone break in?

@mastering92 : Well said. I have nothing else to say, but reinforce what you already articulated.

Thanks, though, for reminding me why I've not posted on here much lately.

Well… good. I am glad you understood. Please continue to stay away from here. Thank you 

I like to call it seasoning as opposed to burn in or break in. Why would one want to burn or break? Seasoning or conditioning. Or in aviation we call it run-up. 

I think your opinion of ASR is pretty accurate actually.

I also believe in "conditioning" your phones for general use and I happen to have Samplitude on my music PC and I can make files of pink and white noise and also sweep tones which again is very handy. When I purchased my Sennheiser 800 phones and Luxman p -750u head amp ( present to myself on retiring ) they as a pair sounded very strident and too trebly. I put my three tone and sweep files on a loop for a couple of days and after that I played music though them continuously for a few days more. At the end of that week I then put them on to have a quick listen and about three hours later I was still in musical heaven. I am not saying that you need to put sweeps and tone files through as i did it because I have a bespoke music computer with DAWs installed. I can assure you it really works. Happy listening !!!
