iPhone-friendly speakers for your summer adventure

Memorial Day marked the beginning of the summer season, which means that with any luck you'll soon be organizing outdoor activities like backyard barbecues, rooftop and poolside parties, and picnics in the park. As you draft your summer checklist for this year, don't forget to pack a travel-friendly speaker dock for your Apple iPhone or iPod.

Unlike Bluetooth speakers, iOS-specific speakers offer the convenience of a docking station that lets you connect any iPhone or iPod with a universal port.

Each of the models below includes a battery option in the form of a built-in rechargeable, or, in the case of the Altec Lansing iMT800, slots for standard disposable batteries. Alternately, when plugged into the wall, these speakers will also rejuice your iPod or iPhone.

Our favorite portable speaker out of the bunch is the Logitech S715i, a powerful unit that packs eight drivers into a boom-box-style housing that's small enough to fit into a backpack, tote bag, or messenger bag. Its rugged details and dual 2-inch passive radiator woofers mean you won't sacrifice durability for sound quality, making it an indispensable accessory in the home or on your next outing.
