Review: Koss BTS1

We all know that judging a book by its cover is wrong, but we do it anyway, right? I know I do. That's why, when I saw Koss's miniature BTS1, I didn't think much of it nor did I expect to be impressed by its sound quality. After all, it's not much bigger than a deck of cards.For $59 (about £103, AU$105 with international shipping costs from Koss' online shop included), this little speaker surprises with sound delivery full of warmth uncharacteristic of its size and a smooth, understated design.
