Neosensory Duo (wristband bimodal) for Tinnitus: What Does the Evidence Show?
Neuromodulation
Current evidence
A consumer wristband borrowing the bimodal idea — sold on one small company-run study.
Evidence strength: Weak (1/5) · Tier 3 — experimental/emerging · Evidence independence: Primarily sponsor-supported.
A vibrating wristband paired with tone playback from an app (10 minutes/day), sold directly to consumers as a wellness device.
Did tinnitus loudness improve?
None shown. No loudness data.
Did tinnitus distress improve?
Limited. One company-run study: TFI −17.9 in the experimental group — unblinded, no sham vibration, all authors are company employees.
Loudness means the tinnitus percept itself became quieter (psychoacoustic matching or loudness ratings). Distress means questionnaire scores such as THI/TFI, sleep, anxiety or quality of life improved — the sound may be unchanged. A THI/TFI improvement is never evidence the tinnitus got quieter.
How strong is the evidence?
Marketing currently exceeds evidence: 1/5 until independent controlled data exist.
Has the result been independently replicated?
None yet. Single company-run trial; no replication.
What are the limitations?
- Single small manufacturer-run study in a minor journal
- No sham control — participants knew their group
- Wrist stimulation lacks the anatomical rationale of tongue/neck approaches
Conflicts of interest: All study authors are Neosensory employees or its founder/CEO.
What should patients know about safety?
Safety evidence: Strong. Benign (vibration + sound).
Is it available?
Regulatory status: Consumer wellness device (no FDA authorization found). Sold as general wellness; no FDA clearance/authorization for tinnitus treatment located.
Availability: Direct-to-consumer online · Europe: Ships internationally · Cost (approx.): ≈$500 device + subscription (varies)
What the studies found
Bimodal stimulation using vibration on the skin (Neosensory Duo)
Perrotta MV, Kohler I, Eagleman DM. · International Tinnitus Journal · 2023 · N=45 (22 experimental, 23 control analyzed) · Controlled study, tones + wrist vibration vs tones-only
TFI change −17.9 (SD 18.2) with the wristband vs −7.5 (SD 15.4) with tones only (between-group p=.04). No sham vibration — participants knew whether they wore the wristband.
The larger −21.8 figure the company quotes applies only to the baseline-TFI≥50 subgroup (n=18). Numeric results sourced from the full-text PDF (International Tinnitus Journal); not present in the indexed abstract.
