Query: Too heavy for lightweight headphones

These "lightweight" headphones are far too heavy to be worn for extended periods of time. The boom microphone only rotates down a limited amount, ending up more or less directly in front of your nose, somewhat obscuring your view of the screen. And finally, the earpads are rigidly fixed in parallel planes to each other, unlike the ears of anyone I've ever met. I bought these to replace a set of Labtec C-322 headphones whose cord had gotten pinched and had exposed wires, but now I think I'll just buy some electrical tape and fix the old ones.
