CNET has a review of the Plantronics Explorer 350 and writes - “On the back is a rubberized earbud with a slight spout that fits securely in the ear. Also on the back is an ear hook that’s flexible up to 180 degrees, so you can use it on either ear. Slipping the headset on wasn’t a problem, but we did find the ear hook to be rather uncomfortable, particularly after hours of continuous wear. The ear hook isn’t detachable, so you’re forced to wear it. The Explorer 350 did come with a car accessory package, which lets you dock the headset in your car via a charging cradle. It also comes with a USB charging cable. However, we were disappointed that there wasn’t an AC adapter included in the package; you have to use a computer or the car to charge it.”
