Bang & Olufsen Wired Earset for Mobile Phones, One Mobile, Right Ear This item was working fine at the time, but I haven't been able to confirm its operation as I don't have an environment to test it. Everything in the photos is included. The EarSet 1 Mobile offers the best voice recognition and listening experience. The speaker unit in the small, sealed cabinet delivers the same ultimate sound performance as the A8 earphones. The EarSet 1 Mobile is an excellent headset optimized for hands-free conversations, providing superior performance whether you're speaking or listening. It has an acoustic structure that reduces ambient noise, allowing for loud and clear audio playback even in noisy environments. The EarSet 1 Mobile offers the same excellent performance as the EarSet 1 Home and can be used with most mobile phones. There are also two versions, for the left and right ears. This unit has a relatively short microphone arm, making it easy and convenient to carry in your pocket when not in use.
