I'm sorry as I do not understand the purpose of the 4' cord. Does it connect at one end to the headband & the other to CD players, iPods, smartphones, computers, etc? If this is true, it seems like it would restrict movement while one is sleeping (I toss and turn a lot while sleeping).

Yes, it would connect to a music device with a headphone jack. You could purchase an extension cable if you needed more length.
