Hiya I have a hand held personal player which you listen to with headphones . When at home I want to be able to use a speaker instead of the headphones .The speaker would have to plug into the headphone socket I realize there is no electrical power coming out of the socket just audio so the speaker would have to be have to be powered independently .I have already tried a mini speaker that runs of battery power but even at full volume I can barely hear it even a small amplifier any suggestions ??. Thanks Keith..
