No.
What you can do with the KS5 is load tinnitus masking sounds onto a DAP with Bluetooth (iPod) and stream them directly to the KS5’s through the Clip+. I have white noise (typical masking sound) as well as a “nature” sound, a babbling brook sound, and my favorite - “wind chimes with rain and distant thunder.”
Honestly though, the hearing aids alone greatly helped me with my tinnitus. My Phonaks have a tinnitus masking feature but I never use it.
