Each participant will wear the Auricular stimulation device during the 30 minutes mindfulness exercise portion of the 2-hour MBSR group sessions. Additionally, they will wear the devices during the 20-minute at-home MBSR activities for the remaining six days of the week, totaling 120 minutes. The total expected duration of device usage per week will be 2.5 hours or 150 minutes.

Mindfulness Based Stress Reduction: This is a standardized and structured training session that was originally developed by Jon Kabat-Zinn. Its primary objective is to assist participants in accepting their current condition and eliminating negative associations with it. All study participants will receive MBSR

Each participant will wear the Sham device device during the 30 minutes mindfulness exercise portion of the 2-hour MBSR group sessions. Additionally, they will wear the devices during the 20-minute at-home MBSR activities for the remaining six days of the week, totaling 120 minutes. The total expected duration of device usage per week will be 2.5 hours or 150 minutes.

The auricular stimulation device produces continuous vibrational stimulation directly to the conchae of the auricle. It is designed to stimulate the vagus nerve for neuromodulation to treat a variety of clinical indications. The system includes a pulse generator and an ear electrode device. Participants will use a vibration motor in a custom-created soft plastic clip for the left ear.

Each participant will receive their own device by mail, which they will wear during the the 30 minutes mindfulness exercise portion of the 2-hour MBSR group sessions. Additionally, they will wear the devices during the 20-minute at-home MBSR activities for the remaining six days of the week, totaling 120 minutes. The total expected duration of device usage per week will be 2.5 hours or 150 minutes.

The responder proportion will be defined as number of participants with >12- point change in Tinnitus Severity Short Form [TSSF] score at the end of treatment compared to baseline, divided by the total number of participants in each group.

TSSF score ranges from 0 (mild) to 100 (severe) The responder proportion will be compared between the active and sham group.

Feasibility of the auricular device will be assessed by recording the duration of device usage each week, summed over 8 weeks, and calculated as a percentage of the total expected usage which is 2.5 hours(per week) x 8 for each participant.

Participants with >80% device usage will be defined as adequate device users.

The proportion of adequate users will be compared between the stimulation and sham groups
