Device configuration. The tinnitus neuromodulation therapy device (neurostimulator T30 CR, left) applied the acoustic CR neuromodulation signals via cable to the "streamer" (Phonak ComPilot, middle) that in turn sent the therapy signals via radio frequency link to the two hearing aids (Phonak Audeo V50, right).

Subsequently (2015-2016), he was treated for 12 weeks with the same neuromodulation therapy device (T30 CR, Neurotherapies Reset GmbH, Julich, Germany, a company of the Brook Henderson Group Limited) but connected to an external "streamer" (Phonak ComPilot,) that was a component of commercially available hearing aids (Phonak Audeo V50 Sonova AG, Stafa, Switzerland), Figure 2.

THI, VASL, and VASA scores for acoustic CR neuromodulation therapy (black bar baseline, white bar after treatment) for two treatment phases. The first treatment phase (a) used only a CR neuromodulation device (T30 CR device with custom earphones only). The second treatment phase (b) used the same neuromodulation device (T30 CR) but combined with a streamer (Phonak ComPilot) wirelessly connected to hearing aids (Phonak Audeo V50).
