Summer is prime outdoor grilling time, which means you’ll want a portable speaker to drag around with you to backyard barbecues. Enter the Big Jambox, the sequel to the very popular Jambox. As the name so subtly suggests, it’s bigger than the original; still, at only 2.7 pounds, you won’t throw your back out when picking it up. Bring it to the party, turn it on, pair it to your smartphone or tablet via Bluetooth and you’ll be blasting Hall & Oates in no time. See Harry’s review of the Big Jambox for more info.
