After about a year the cheap plastic extendable headband snapped on me when I tried to put the headphones on.

The plastic is pretty solid and feels good, but I am a little concerned about two little cables running from the main body of each ear to the bridge on top

The plastic was brittle and basically crumbled

Pro is more plastic and SRH840 seems more solid (though I don't like the exposed wires)

I dont feel complete isolation and in some parts the plastic feels a little weak

Upon closer inspection, I could see how they would break, because there is only a skinny molded piece of cheap plastic that makes up the earphone brace.

They will not send me the small, cheap plastic part that needs replacing

After taking a pretty hard beating they finally broke (the plastic that connects the headphones to the band cracked), but these are amazing headphones.

They use a very cheap plastic that broke under pressure twice in the first year on both sides

I've seen stronger plastic in a model car box.

Why are these expensive headphones always built with such crappy plastic?
