Well, I bought a new headphone for my Bookport today. The headphones have a very bassy response. I like to hear more of the high end when listening to speech. This leads me to make the following suggestion for future enhancements - it would be nice to have a setting to change the tone control (for treble and bass) of the Bookport. I don't know if this is at all possible with the current Double-Talk hardware, but it would be nice some day down the road. -- Pete
