How long is the cord from the 3.5 connector to the ear buds?

Thanks for the really rapid reply. The 50" length is certainly more than I need, but better to have more than not enough;)

What is the Sensitivity, and/or SNR (Signal to Noise Ratio)?

cant answer the sensitivity or signal to noise question but, i will say that they are comfortable and they sound real good hooked up with my zen touch, i am impressed

Do they have a microphone?

No mic or controls to skip songs.
