It emphasizes that the main body goes deeper into the ear thanks to its compact size and that it can be safely installed because there is no protrusion that touches the ear.

The basic performance is a 2-way unit configuration. By combining a woofer and a tweeter, it is configured for a wide range of reproduction from delicate treble to loud bass. It is also equipped with active noise cancellation and external sound capture functions, which are essential for high-end wireless earphones. The ANC noise reduction effect is 98%, and external sound capture can be set in three steps.
