A König piece found here
, some German brand that apparently is quite popular here in the Netherlands. Not as good as a Sennheiser (or so I've heard) but a decent and cheap (<40$) pickup nonetheless, it has been lasting 3 years now, and the only thing wrong with it is the mic cover coming off. Other than that the audio quality is fine. It's a bit rough on the ears when worn over glasses for multiple hours, but that doesn't really come up often.
