Hi Donna and list: Yes, I have used a similar strategy and concur that it does work. I have also found that I don't need near as much volume from the Bookport when using the TDK Imaspeaker. In fact, I only use headphones when I might be disturbing others. Fortunately, I can keep this requirement to a minimum. So as long as I use the speaker, generally set the volume at 33, and the batteries last a log longer, even though I read mostly audio files. Always keep the phones handy, though. In this way, I nor anyone else is inconvenienced. Cheers, Dave
