Anyways, you should put the modded firmware 4.00 on your R1. It's the only safe firmware.
Tried different headphones. All files sound great. Apparently, the R1 will not work with the extension cord on the Sennheiser MM6. Also tried without extension, and sounded fine. The MM6 pones with the extension sound great with all other players, including other Samsung players. So who knows why they do not pair well with the R1. Just happy to have figured it out.
