Why are wireless headphones so rare?

I had to walk through two feet of snow to get to school, and had to cut through a unplowed cemetery to boot. To make it worse, I had to do this wearing Levi's, carrying my books and smoking a Marlboro with one hand and a ghetto blaster with twelve D batteries in the other. Then I had to go to ski club after school and do it all over again. Luckily the Walkman had just been invented and I could crank cassettes on the chairlift through my $200 Walkman which cost more than my skis and boots combined. Doesn't anyone roller skate with a ghetto blaster on their shoulder anymore? I don't have a problem with wires. I notice them but they don't bother me because they've always been there.

Bose just came out with a wireless Bluetooth headphone, the AE2w that has some nice features. Very lightweight and comfortable they will pair with any Bluetooth enabled device.

@Kijanki, you may get sweaty using one of these. :)

I had to walk uphill to school.... and uphill back from school to home!!

You poor saps. I remember riding my bike to school with an ashtray strapped to the handle bars listening to my crystal radio!

Oh, wearing sunglasses. In the WINTER!

Back in my day, while walking through waist deep snow 2 miles to school with a hot potato in my hands, we tied a transistor radio to our neck and it was good enough.

Well if thats the case, than the other wire to the player can balance things out and give you some extended range. Kind of like if you biwire speakers. It allows you to use 2x the amount of cables without having the negative effects of the extra length.

Solar powered wireless headphones - next invention.

"The headphones have to have some sort of power. It would be batteries...
So either the phones would be really heavy to last, or, you would be changing batteries every few days."

You could keep the batteries in a separate pack and just run a power cord to the headphones. And use rechargeable batteries.

"Why do people keep putting up with the hassle of wires? Is it just a lack of knowledge about wireless headphones?"

That may be one reason. For example, I know little about them these days. Are there wireless headphones that test out as well as wired for sound quality? Should be possible, but I have not noticed anything so far (though I have not investigated thoroughly) so dunno if any like that?
