Audio with studio quality, elegant design and eight hours of tangle-less freedom. That is what Vasa Blå from Sudio stands for. Just connect the earphones with your smart device. Of course you can answer calls and control your phone with the remote. Vasa Blå is compatible with all bluetooth devices. The Vasa Blå sound signature is delivered by a carefully tuned driver and amplifier. The combination of driver and amplifier is able to separate the sound of every instrument in every song, thereby giving the listener a true studio experience.
