This is my biggest pet-peeve. I bought a pair of bluetooth headphones that sound pretty good for their price (Cowin for about $50). They offer a corded option, so I can use them when a plug is needed, like watching a movie on a plane. BUT they will not work at all, even in corded mode, unless they are charged. If I forgot to charge them, I'm stuck with nothing and they are too bulky to deal with that. So now they get used at home and I travel with cheap earbuds.
