I have the same handicap of a deaf right ear but normal hearing with my left ear.
Last week I bought the Sansa Fuze 8GB hoping that I can connect it with my mono earbud (Hama In-Ear Mono Earphones HK-200, impedance 32 Ohm, Sensitivity 96 dB) but I got dropouts while playing music.
Mostly I hear audiobooks which are normally in mono and use one side of a stereo earphones but I need also a solution for hearing music.
Are there any plans for future firmware releases that there will be a system setting like using the Sansa Fuze Radio to hear everything in mono.
Thanks for the reply
