The worst headphones ever? Not just some bad ones, but the actual worst?
Most of you here would probably describe this as obscene, but the worst headphones I ever listened to were free earbuds out of a kids airline lunch! They weighed about 0.2 grams, were shaped like dolphins, and didn't fit in my ears. Can't really describe 'em... they made the no-name earbuds I usually used seem REALLY good.
Comfort: Uh... it was the material of cheap plastic
packaging.
Build quality: None, obviously
Sound quality: Almost as good as the internal beepers used in old tower computers...
Volume: MUCH too quiet to hear, no matter how much you amped it
(more amp=more crackles, that's all)
Overall feel: Reminiscent of a spider web in one's ear
Durability: Last as long as you can avoid putting them in the trash (not very long!)
Isolation: All outside sound can be heard just as well as if you had a peanut in your ear... but the person next to you probably can't hear them any better than you can.
Experience: Funny. Not really miserable, because it was so bad that it wasn't even like a headphone at all... just a quiet crackle-generator!
All this, and I still managed to use them with an old cassette player for an honest 5 minutes! Now
that takes a real strong gut!
