Bang&Olufsen H4 Disassembly

You are probabaly here, because you have an issue with the right hinge on H4. I started to have problems with them during the warranty period, but well, didn’t care enough. But a couple of months after 2 year warranty the hinge got blocked entirely and they were no longer usable. So I decided to open these beatiful and quite expensive headphones. I didn’t have time, tools, knowlege and mood to fix it yet, but I was able to open it.

EDIT: I fixed it somehow with plastic fasteners, but they are very fragile now. Ok as headphones to use with a computer or listening to music inside.

• earpads are detachable by hand, not sure why everybody say they’re not. Nothing special is needed, just a little of force in perpendicular direction
• earcups are held together with plastic clips inside - I used shitload of force on the hinge to open it since the hinge was broken anyways. In normal cases use a guitar pick tool to open the shell
