I hate hate hate the tour radios, often called Whispers, and the wired earpiece that comes with it. I do not want the thing dangling from my neck, so would usually place it in an outside pocket of my bag and struggle with the wired earbuds getting tangled.
So this year after reading some reviews I decided to spend a big $35 on a TwelveSouth Airfly bluetooth transmitter and use my own bluetooth earbuds (Anker) and what a difference! I am sure you can use whatever bluetooth transmitter you want, but this worked well for me. Whisper went into my bag with the transmitter, one earbud went into my ear and I was good to go. Sound quality is vastly better and I could adjust volume on my earbuds rather than the tour radio.
Also worked very well for movies on the plane - no wire connecting me to the seat, better sound quality and volume control.
