Hallo!I've bought Sony walkman NWZ E-354 in France...Of course it has volume limit...After entering in service menu & reseting- sound became much louder...But when I'm listening to the songs with high bass-sound becomes low...what would you advise me?If there is a chance I'd like to find a fimware which is not for EU-without volume limit...Unfortunately, all models which were made for EU are with volume limit...Thanks for answers!
