The issue -- you love the music you have on your i-device, and you'd like to have access to the content while not having to use your earphones or ear buds as you move around your home, home office, or shop. The solution -- a speaker dock that accommodates your device, uses a local wireless network, and streams your music wherever you wish without your being wired up.
Use this speaker dock indoors or out -- the Yahama PDX-11 Portable Player Dock ($100); drop your iPhone or iPod in the receptacle and take off for the basement or the back yard. Powered by either alkaline batteries or a 110 volt source, this speaker dock is built for top-flight portable sound, with a 4" woofer and 1 3/8" tweeter inside the 3.3 pound case that sports a metal carry handle and a protective, perforated steel front grill. Other conveniences -- a remote controller and a stereo input mini-jack. This speaker dock is just made for back yard picnics or car washing duties in the driveway. Nice.
Got an iPod, iPhone, or iPad; or all three? Any of these electronic gadgets will be right at home in the JBL On Beat Air Speaker Dock ($130). Use them in this powered speaker system to stream the tunes you've so faithfully installed on your media player. Control the action with the included remote, or your device's control panel. The full, rich sound emanating from the speakers? From a pair of JBL Phoenix SE Full-Range speakers. Docking your device also puts it in the charging mode, via the ac power adapter. Multitasking at its optimum.
For a dock that is ideal for the beach or a stadium parking lot tailgate party, check out this iPhone/iPod-compatible Sony Compact Speaker Dock ($67; was $86). Lightweight (at fewer than four pounds) and compactly proportioned, the speaker dock is good for up to 10 hours playing time on the AAA batteries. It's not a big blaster speaker dock, with a pair of 2 watt speakers, but it'll do the trick. Control it with the wireless remote.
