Saw this at JB online and in store (Melbourne, Elizabeth St).
Reviews for the speaker are pretty good and below RRP which is $249 and seems to be better than the UE Boom 2 which is an Ozbargain favourite

The kicker for the deal is the free earphones. RRP is $299 but they are very overpriced.
Review here on the earphones
