Premium, 100% wireless in-ear headphones featuring outstanding Bang & Olufsen Signature Sound and an intuitive touch interface for controlling music and calls, as well as voice control. The E8 offers a perfect fit tailored to the ear and comes with a genuine leather charging case for on-the-go charging. With a playback time of over 4 hours, you can take the E8 with you wherever you go. In transparency mode, you can easily toggle ambient sounds back on through the four transparency levels in the Beoplay app with just a simple hand gesture. For better connectivity and to prevent sound degradation when passing through human tissue, the Beoplay E8 uses NFMI (Near Field Magnetic Induction), an audio streaming technology that transmits sound from one headphone to the other via a magnetic field. This allows the master headphone to deliver sound to the slave headphone without loss of quality. The NFMI technology is the digital wireless technology currently used in hearing aids. When making calls or listening to music, the right headphone can also be used as a standalone device. A charging time of just 20 minutes provides you with an hour of music enjoyment.
