Individual sound, absolute tranquility.

Active noise cancelling and sound personalized by Mimi Defined™ finally combined.


State-of-the-art technology, personalized sound

The new beyerdynamic headphones Blue BYRD ANC and LAGOON ANC revolutionize the wireless music experience through the unique combination of the latest active noise cancelling and with sound personalized by Mimi Defined™.

Mimi Defined™ powers sound personalization in beyerdynamic’s MOSAYC products by testing users’ hearing and adapting sound output to their unique profile. Users can test their hearing, control sound personalization, and shape their experience using the MIY (Make It Yours) smartphone app. With beyerdynamic’s high-quality design and the combination of ANC and MOSAYC, the growing product-line of headphones creates a completely new, individually-adapted sound experience with unprecedented detail.

Dynamic sound personalization

Hearing is a highly individual experience that changes over the course of a lifetime. Like in a mosaic picture, individual pieces get lost, changing the acoustic picture, rendering it incomplete or fading. Subtle details get blurred out, single frequencies or tones vanish. The innovative MOSAYC sound personalization by beyerdynamic restores the picture, using Mimi Defined™. An individualized hearing profile is calculated after a hearing test in the MIY app for Android and iOS devices. 

With the resulting personalized hearing profile, the sound of the Blue BYRD gets adjusted to the individual hearing capability of its wearer. It replenishes the missing pieces of the mosaic so to speak, to attain a complete and brilliant sound picture that shines in all its vivid colours and vibrant details. The individualized listening profile is also stored inside the Blue BYRD,
