Query: Good enough sound, but breaks readily & can't be repaired

I like the sound fine, but the headphones have a couple of ways of breaking: where the over-the-head plastic joins the u-shaped yoke attached to the earpiece, and where the earpiece mount pivots in the over-the-head plastic. They're just too cheaply and flimsily made. Nothing like seeing $150 bite the dust just because of some broken thin plastic parts. :(
