a weird problem with my headphone jack. With some devices, my portable speaker or my Koss portapro:s for example, it works very poorly, the plug kind of pops out a bit and there's connection problems, crackling and such. Then again, when I plug in the phones HTC supplied with the phone OR my Koss sparkplugs they work perfectly!
All phones work normally with other jacks.
Weird, shouldn't all the 3,5mm connectors be basically identical, but some work and others don't? Anyway, anyone got similar experiences?
