We’ve no idea why ‘great’ is spelt wrong and we don’t care. We’ve been too busy blasting out Miley Cyrus dross via this titchy iPod speaker. Yes, she’s a brat but she gets googled a lot more than the word ‘grayt’ so she’s well worth mentioning. And if all you baffled tweens think that’s confusing, try shoving batteries in this take-anywhere speaker because – ta-dah! – it doesn’t need ‘em, it simply piggybacks power from your player.
