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 !!!
