* You might have to get a screwdriver in between two hinged parts, until you can discover where there is one or two posts in one piece which emerge from the joining piece.

* If the phones have foam earcushions, there might be screws hidden beneath.

* It is common to see tab-and-slot type fasteners. The tab has a ramp shape making it easy to insert, until it goes past a stop, setting it in place. This is difficult to get apart without breaking something. If the slot is accessible, then try inserting a screwdriver, you might be lucky enough to bend the tab away from the stop, and separate the pieces. Often the slot is not accessible, and all you can try is to separate the joint with a screwdriver, watching for a spot that you can push on to separate internal tab-and-slot connections.
