You can enjoy and share your music from an iPad or smartphone with small attached speakers (see previous post) or larger wireless speakers (see previous post), but sometimes you want to listen by yourself, with headphones.
And if you're hooking headphones up to an iPhone or other smartphone, then it only makes sense to add a microphone so you also can use the headphone for calls.
And, of course, it's clumsy to deal with a headphone cable to a small device that lives in a pocket or a bag, so the headphone might as well be wireless as well.
Which explains the Logitech Wireless Headset -- A nicely designed Bluetooth headset that pairs to up to eight different devices, including the iPad, iPhone, iPod touch, and other players, tablets, and smartphones.
You can enjoy your music, and then transition to phone calls -- and use it for FaceTime video calls.
The Wireless Headset has an adjustable headband with soft ear cups for a comfortable fit, and folds up for travel. The noise-canceling microphone rotates up to nest under the headband while listening, and then folds down to position for talking. [Yes, the picture is a visualization -- there aren't four mics...]
It charges over USB, and runs for six hours. One earpiece has power, mute, and volume controls.
Logitech Wireless Headset lets you listen to your personal music from a variety of devices -- tablet, phone, computer -- and then switch to phone or video calls without swapping around your gear. It's available for $69.
