Latest Resound Models

ReSound's roster of hearing aids feature contemporary, simple designs that are discreet but full of the latest features.

ReSound usually provides three types of technology in each of their hearing aids. They name each platform differently, but each platform will often have a full range of hearing aid types (except for the Quattro). These levels of technology are typically numbered 9, 7, and 5.

LiNX Quattro

The LiNX Quattro is the flagship hearing aid model. LiNX Quattro models come in different fit styles, including two RIC styles and CIC, ITE, and MIH (mic-in-helix) models, all featuring custom-designed earpieces explicitly made for the user.

LiNX Quattro has an improved dynamic range and a higher frequency of bandwidth than previous versions, as well as improved computing and sound insulation capabilities. Users enjoy ReSound's most precise, best quality sound profile in any environment with the LiNX Quattro.

This model offers direct streaming from virtually any device and is a Made for iPhone hearing aid to allow a Bluetooth connection to any Apple device. The LiNX Quattro rechargeable models also come with an included portable charging case.


Due to Spatial Sense and Binaural Directionality technology, the LiNX 3D offers advanced 360-degree speech recognition and noise control in almost any sound environment.

The LiNX 3D comes in a wide range of suitable types, including an RIE (receiver-in-ear), rechargeable version, several versions behind-the-ear, and even a custom-made option in either in-the-ear or fully-in-canal sizes.

This device is Made for iPhone, though it may also stream from Android and other devices with additional accessories sold separately. LiNX 3D is compatible with Resound's Smart 3D app.

Enzo 3D

Enzo 3D comes in two separate behind-the-ear versions, featuring the Binaural Directionality III feature of ReSound that helps users distinguish where sounds come from in almost any sound environment. Users also benefit from advanced feedback reduction and industry-leading amplification, telecoil, tinnitus therapy, and 'Made for iPhone' Bluetooth compatibility.

The BTE version of Enzo 3D offers up to 12 days of battery life, even after streaming for up to four hours a day. This model is available in 10 colors.


ReSound also leverages smartphone technology to include ReSound Smart Fit — sophisticated software that provides users with access to professional customer service, fine-tuning supported by audiologists, and a more precise fit. The ReSound Smart Fit software eliminates the need for in-person tuning appointments as it provides the ability to make hearing aid changes remotely.
