This is particularly true for portable speakers, which can be found in abundance across the Web. The latest from Memorex, dubbed simply a Foldable Travel Speaker, isn't much of a standout offering. But its affordable price tag ($59.99), relatively compact size, and simple aesthetic will certainly appeal to some. Sound quality, however, fails to impress.
