Summer has officially started, which probably means you’ve been grilling. If you need a little soundtrack to go along with your charred meats, think about checking out today’s Hot Deal.

We found the JBL On Stage Micro III Portable Loudspeaker available at J&R for just $39.99. Less than 40 bucks? We’re spent more on party chips and dips. That price is actually $60 off the list, and even includes free shipping.

The JBL On Stage Micro III looks insanely small, because it is small. In fact, it’s small enough to have grill-side or even to throw into a bag for the beach or someone else’s BBQ. It weighs less than a pound and works using four AAA batteries, which promises about 12 hours of playtime.

Inside this tiny package, there are two JBL Odyssey full-range transducers and a digital amplifier to crank out sound. If you don’t want to use the dock, the device also has a USB port and an auxiliary input, for connecting other devices. If you do dock an iOS portable, it’s easy to navigate through, via the included remote.

This is a great deal, so you may want to snag one of these for your next party or maybe just for the bedroom. However, you’d better do that soon; this sale ends on June 23, 2012, or whenever the retailer runs out of stock.
