Amazon had the Ex81's for $31.92 - I just ordered them. Thanks.tensionrev said:Get the plug type, like the sony ex 51, 71, 81... not exactly sure of the model numbers, but you can find them for around $30 with no problem either online or at one of the big box retailers (BB, CC, etc.) They don't make you completely deaf to the world, and you don't need crank the volume up to hear clearly. For $30, they don't really sound great, but you won't know that unless you buy some headphones that do sound good, which are, of course, more expensive. To you, they will sound right about on par in terms of quality to the packed in buds, but more bassy and less trebley.
