I've and possibly you have been seeking thru youtube, internet, the Television, advertisements.
and for me, im starting to see alot of advertisements about portable speakers?
Bose has already been in a big part of the compact portable hifi speaker.
but i guess you can say Sono's whom made a commercial, started creating a stir.
Then Beatsaudio made their own; The Pill.
then Jawbone made their speaker.
I dont think it is to talk about much on a forum as here, but just letting everyone know about this increase in trend.
