AEX50

"Uses SMP iFit®, a shape memory polymer made by SMP Technologies.

The SMP iFit® material from SMP Technologies, a Japanese company, is used, which has excellent shape recovery and fixation properties, providing a stable fit. In addition, the mechanical vibration absorption, which is the value that indicates the time it takes for the earphone to return to its original shape when force is applied, is designed to be close to that of human skin, and when used on the ear tips, which are the parts that come into contact with human skin, it provides a natural fit and feels comfortable.

SMP iFit is a registered trademark of SMP Technologies, Inc. US patent pending.

Unique double wing design

The wide wing part fits snugly around the ear canal entrance over a larger area than regular ear tips, and the material maintains its shape when worn, so there is no need to insert the ear tips all the way in, making them less likely to feel uncomfortable. 

Sizing by data accumulation

When developing earphones, we use the knowledge we have gained from the 3D custom-fit inter-shell "ST1000/ST300" to set the size.

Logo case included

This product comes with a case with the Acoustune logo that can store up to six pairs of ear tips. You can use it to carry or store spare ear tips.
