The Bowers & Wilkins C5 earphones offer excellent sound and a unique "loop" design that helps keep the earpieces securely in your ear.
Slingbox
The Slingbox transmits live and recorded TV from your home to wherever. It installs between, say, your cable box or DVR and your TV and connects to your home network. Then you access that setup via your laptop, smartphone, or tablet. This is great for things like watching local sports and keeping up with "Mad Men" when you're on the road. And the Slingbox is a subscription-free device; once you pay for it, it's paid for. One thing worth mentioning is that the SlingPlayer apps for Android, Kindle Fire, iOS and other mobile devices cost $30.
Nike + iPod
Dads who are runners will find the Nike + iPod kit useful. The custom sensor fits inside of Nike shoes and syncs to iPods to track workouts.
