By ripped off, if you mean the detector headphone companies are charging more that they should? Definately not.
Designing, buying and selecting parts, research on all the detectors that could be hooked up to them, business expenses, licensing and taxes and shipping and advertising....... there is very little profit after all is done.
Maybe the China companies that sell pretty much disposable phones actually make the killing.
You want comfort, good sound and reliability. Buy what makes you enjoy the hobby just a little bit more.
My 1 and 3/4 cents
