Auri uses a series of transmitters within the auditorium to broadcast an Auracast program stream to a receiver worn by the user. Birmingham Hippodrome provides dedicated Auri receivers for patrons to use. Users can choose what program stream to connect to and adjust the volume to suit their needs. Auri is also compatible with third party Auracast devices enabling users to provide their own Auracast enabled listening devices such as headphones or earbuds.
