Styles requiring a custom fit or a custom earmold can't be effectively demonstrated without having them manufactured based on an impression of your ear. Additionally, since new technology emerges at a rapid pace, keeping a large inventory of many makes and models for demonstration isn't practical for most providers. To ensure your satisfaction with hearing instruments, most states require a cancellation period - a specified time period within which you can return the hearing instruments for a refund (usually a fee applies for the professional's services). But remember - returned hearing aids can't help you hear better, so give yourself every opportunity to succeed with your instruments by working closely with your professional for follow-up and finetuning and ensure your satisfaction.
