How many hours can the Hifiman R2R Red play in hifi mode (old and new firmware) ? I just sold the R2R red , the buyer just ask how long does the battery last, he gets only 4.5 hours from the player ? ฺBy the way, right now he still uses the old firmware , I think, because there is still ecomode to be selected. Thank in advance.
(I just searched the thread to find information about batttery life , some say it can play up to 7.5 hours in hifimode , some says that it can play only around 4-5 hours.)
