Hello all, I just purchased some nice Sennheiser HD 650s about 3 months ago. A little while ago I noticed some crackling at very low frequencies, in the intro the the song Angel, by Massive Attack this is very noticeable. It used to only be in the right can, but now it is showing in both cans. The crackling is also noticeable when there is a bass punch. I am using my built in audio on my PC, I tried both the front and rear outputs, and using my phone as I have no other audio sources at the moment. The crackling almost sounds like sand, it is very faint, and at the same time it sounds like a vibration. I would like to know if cleaning would help (never done that before but sure I can find a guide on here somewhere), or what any other causes could be.
