Custom Fit with FenX
FenX replaces the traditional audiologist visit entirely. The old way meant booking an appointment, sitting for ear molds, mailing the impressions off, and waiting weeks for your tips. FenX handles all of it with an at-home phone scan.
It works in three steps, Scan, Fit, Ship:
- Scan. Capture your ears with the FenX app. No audiologist, no molds, nothing to mail.
- Fit. FenX AI technology reads your scan and dials in the shape for a comfortable fit and reliable performance.
- Ship. Your custom ear buds arrive in about a week, ready to use.
Select the FenX Custom Ear Buds option on the product page. After checkout, you’ll receive a QR code with instructions to download the FenX app. Our team ships your product and registers you in the system, then you scan your ears whenever it is convenient.
