You have an MP3 player and a cellphone, but listening to one usually precludes talking on the other. Skullcandy’s (which is a horrid name for a company) new LINK headphones connect to both gadgets, so you can actually listen to music while you talk on the phone. You can also turn the volume all the way down when you have a call, if that’s your thing. How does it work? The LINK has a tiny microphone built-into the cord so it can double as a hands-free headset, and comes with two jacks – one to plug into your portable audio player, the other for your cellphone.
