Is there a trial underway?
EDIT:
So I found this on ClinicalTrials.gov:
So 2024 is in my opinion the best guess for the device to come to market. That is a long time to wait. But reading this fills me with a lot of hope.

"Overall, the loudness of phantom sounds decreased only after the actual, or bimodal, treatment, but not the sham treatment of sound only. For some, the decrease was around 12 decibels, about the equivalent of making it half as loud. Two participants said their tinnitus disappeared."
"We're definitely encouraged by these results, but we need to optimize the length of treatments, identify which subgroups of patients may benefit most, and determine if this approach works in patients who have nonsomatic forms of the condition that can't be modulated by head and neck maneuvers," says Shore.
