Compatibility with hearing aids and headphones
Allow a means for hearing aids to connect directly, for example via Bluetooth, to allow audio to be transmitted directly to the device without interference from environmental audio.
For communication that requires use of a device that transmits directly to the ear, e.g. a headset, hearing aid compatibility is a legal requirement.
Similarly, where hardware includes an integrated speaker, ensure the audio can also be accessed through plugging in headphones. If this has potential to apply to any communications related audio, headphone connection must be through an industry standard (i.e. non proprietary) connection.
