Unlike it’s predecessor the Phonefone III will not break the bank. The design is simple and uses acoustics to bump the sound up 60db, roughly 4 times louder. It is a pretty interesting device since it does not require any electricity to work. The design itself is a little bit retro, but it does get the job done. The one question is, is if it is worth the $200. The first batch of these powerless speakers is only 50 models so if you are all for great acoustics over a normal speaker it is a great gift for that music lover with an IPhone 4 in your life.
