Jabra EarSet All-In-One Descriptions:

Jabra EarSet™ is the only all-in-the-ear speaker and microphone that lets you keep both hands free to anything and talk on your cellular phone. With Jabra   EarSet, there is nothing over your head, over your ear, or in front of your face. The EarSet uses the patented EarGel for a secure fit and outstanding hearing. Smaller and lighter than a quarter, the EarSet is a comfortable and stylish alternative to bulky headsets or noisy car speakerphones. The EarSet channels sound directly into your ear canal for excellent audio quality, especially in noisy environments where it is superior even to a phone handset. The fixed distance between the EarSet's microphone and your mouth ensures consistent transmission quality as you move about naturally. The unidirectional microphone enables you to speak naturally and be heard , and so will the person you're calling. Not only does the portable EarSet provide a safer driving experience, it also keeps the phone antenna a safe distance from your head.
