Hearing aid buyers usually face a tough choice: powerful behind-the-ear devices or discreet in-ear models with compromised audio. Phonak thinks it's found the answer with the Virto R Infinio, which uses custom ear molds to deliver BTE-level performance in an invisible package. The breakthrough could reshape how people think about prescription hearing technology.
Phonak just changed the game for people who want invisible hearing aids without sacrificing sound quality. The company's new Virto R Infinio breaks the longstanding trade-off between discretion and performance that's plagued the industry for decades.
Most hearing aid users face an frustrating choice right from the start. Behind-the-ear models offer the best audio experience but sit visibly outside your ear. In-the-ear devices disappear completely but traditionally deliver inferior sound due to size constraints and microphone positioning inside the ear canal instead of outside it.
Phonak spent years trying to close this gap, and the Virto R Infinio represents their most ambitious attempt yet. The device exclusively uses custom-fit ear molds - technology that's been available on high-end studio monitors and luxury hearing aids but rarely deployed at scale.
The molding process isn't simple. Your audiologist has to inject a specialized compound directly into your ear canal, wait for it to set, then carefully extract the hardened impression. It's the same technique used for custom earphones that cost thousands of dollars.
"The custom fit changes everything," according to WIRED's Christopher Null, who tested the devices extensively. The precision molding allows Phonak to pack more electronics into the available space while ensuring optimal microphone placement.
This matters more than you might think. Traditional ITE hearing aids struggle with microphone positioning because they're essentially trapped inside your skull. Sound has to bounce around your ear canal before reaching the device, creating delays and distortions. Custom molding lets engineers position components exactly where they need to be.
The Virto R Infinio also tackles the battery life problem that's plagued smaller hearing aids. By maximizing every millimeter of available space through custom fitting, Phonak can include larger batteries without making the device bulky or uncomfortable.
This represents a significant shift in thinking for the hearing aid industry. Most manufacturers have focused on making one-size-fits-all devices that work reasonably well for most people. is betting that true customization - despite the extra cost and complexity - will attract users who've been forced to choose between good sound and invisibility.
