Query: A good idea needing refinement

I thought this pillow would solve my problem of going to sleep with music and not disturb the rest of the household. While the pillow worked as designed, the design needs improvement. The reciever and the transmitter should be activated and shut off through the music player. It doesn't make much sense to have to wake up to turn the device off -- and if you don't, it has a healthy appetite for batteries. The quality of the speaker leaves a lot to be desired, also.
