BE FREE
The beyerdynamic Blue BYRD stands for wireless freedom. With its unique, extra flat design, it combines exceptional wearing comfort with a multifaceted world of sound – along with tremendous Bluetooth® transmission and MOSAYC, the dynamic and innovative sound personalization technology.
POWERFUL SOUND
Beyerdynamic Blue BYRD delivers superb Bluetooth® transmission with the help of the latest audio codecs. Whether you use Android (Qualcomm® aptX™) or iOS devices (AAC), you can always enjoy balanced, great-resolution sound with up to 6 hours of playing time!
MOSAYC - ATTENTION TO DETAIL
Our sense of hearing is unique and changes over the course of our lives. Like a mosaic, some pieces of the sound picture get lost or they fade. The unique MOSAYC sound personalization by Mimi Defined™ compensates exactly this development and adjusts itself precisely to your hearing ability. With individual sound personalization, the missing tiles of the mosaic are restored. And you can enjoy the full sound picture in all its colorful splendor.
And it's really easy: Download the MIY app for Android or iOS, apply the sound profile by Mimi Defined™ and experience a splendid sound picture – in all its glorious detail.
IMMERSIVE USER-EXPERIENCE
Sit back and enjoy your favorite series or videos: The beyerdynamic Blue BYRD comes with the aptX™ LL codec for low-latency sound transmission, making it ideal for TV shows and videos.
EXTREMELY COMFORTABLE TO WEAR
Ergonomically shaped housing ensures a secure and particularly snug fit in the ear. Thanks to the flat shape of the housing, the in-ear sits discretely in the ear and is therefore ideal when relaxing or sleeping without any discomfort.
PERFECT FIT
Five pairs of eartips in the sizes XS, S, M, L and XL ensure the perfect fit for your ear. The silicone used to make the eartips is soft, silky and adapts perfectly to the auditory canal, thus allowing you to enjoy the best possible sound reproduction.
IDEAL FOR YOUR LIFE
The universal three-button remote with microphone provides you with full functionality on both Android and iOS playback devices. As a result, you can flexibly manage your media playback, phone calls and virtual assistants (Google, Siri, etc.).

SOPHISTICATED DESIGN

TRUE RELIABILITY
Robust and durable – these features are an integral part of the beyerdynamic BYRD series. Therefore, beyerdynamic only uses exclusive, high-quality components in its in-ear headphones.
HIGH-QUALITY MATERIALS
Beyerdynamic Blue BYRD’s elegant faceplates are made of anodized aluminium. The beautifully shaped cable has a soft surface and is conveniently worn behind the neck. Thanks to its special qualities, cable noise is kept to a minimum.
EXTREMELY SUSTAINABLE
Simply practical: Eartips and protective grilles can be easily cleaned or replaced. You will find spare parts for all replaceable components in the beyerdynamic online shop. And no matter how intensely the headphones are used, you are assured lasting enjoyment – day after day.
