We conducted a study of 91 patients with severe-to-profound asymmetric hearing loss to assess their satisfaction with digital contralateral routing of signal (CROS) or bilateral contralateral routing of signal (BiCROS) hearing aids. Satisfaction was evaluated on the basis of the number of patients who elected to purchase their hearing aid following a free 30-day trial and on the results of a subsequent 8-question survey. We found that overall patient satisfaction was generally high. At the end of the 30-day trial, 66 of the 91 patients (72.5%) elected to keep their CROS or BiCROS device, a percentage that is far greater than the acceptance rates of 10 to 20% that had been previously reported with older models of the CROS and BiCROS devices. According to the survey responses, those who kept their devices gave them an overall rating of 3.4 on a scale of 1 (very dissatisfied) to 5 (very satisfied); those who returned their devices gave them an overall rating of 1.9.
