Can I use just one earbud independently?
Yes, you can use either earbud independently for single-ear use. Press and hold the multi-function key on your preferred earphone for 6 seconds and release when the red and blue light flash alternately, then enable Bluetooth on your phone and search for 'Air plus' to pair. (Page 10)
