I soooo really wanted to love this device but was very quickly disappointed, the sound quality was good thats a plus but the estimated battery life was very very wrong, Sony say 7 hours talk or music time & 130 hours stand by but all i managed to get was a max of 3 hours then day by day it got less & less until finally the longest it wold work for on one charge was one hour, ok most people will think that thats what happens to battery''s after long time usage but hey NO i am only talking about after 4 days of using the unit, in conclusion Sony should be ashamed to sell this under the good name of Sony, As the units only the size of a AA battery they could have made it work from a AAA battery at least that way you could change the battery when it died rather than end up carrying dead weight after its died............my advice read reviews before you buy.
