These are the receivers used on Phonak's Audéo B, Audéo V, Audéo Q and Audéo S models of hearing aids.

xS - Standard receivers are the least powerful. Used for mild to moderately severe hearing losses. They are available in sizes 0, 1, 2 & 3.

xP - Power receivers are the most powerful. Used for moderately severe to severe hearing losses. They are available in sizes 0, 1, 2 & 3.

PLEASE NOTE: It is very important that you do not change the power level of the receiver without a visit to your hearing health care specialist for programming changes. If done, it will change the volume levels and frequency response of the hearing aids. This will result in a reduction in sound quality and the potential to cause further damage to your hearing.
