We are offering with each  basic set LK-001, LK-002, LK-003 two packages:

The S model and the P model.

The S model can be upgraded to the P model. The S model has the minimum of components to have a working hearing aid, and it also has all the interfaces if you want to connect your TV, Bluetooth earphone or Bluetooth headset. You don’t need to buy additional accessories

The P model comes with additional microphones and earphone including a compatible Apple Airpod Pro earbud. With this earbud and an iPhone you can use your smartphone as an hearing aid. See in the menu Apple 

As microphones and earphones are in $5-$5000 price range, among the thousands of the devices that can be attached to the audio-kit LK-001, LK-002 and LK-003 we have selected a number of microphones and earphones and we have packaged them with our introductory offer at a special price to show you the interchangeability of the components composing an hearing aid.
