I just bought a pair of HD 598 and noticed that I would get an occasional ting sound, almost like a prick with a ring, in the right cup. Has anyone else experienced this and should I be worried? I've contacted Sennheiser and still waiting for a reply.

I'd say a prick with a ring is always a worry.

I haven't noticed anything like this with my 598's and I've had them for a few years now.
