*Due to the nature of Bluetooth technology, users may experience a slight audio latency when watching video on a portable device. The headphones are working fine. This is a characteristic of all Bluetooth headsets. Latency is not an issue for audio-only use, OR when using the included detachable headphone cable for a wired audio connection when watching video.
