Of course, it was made on miniature Korg Nutube 6P1 double triodes , but even this allows us to talk about a unique approach. Headphones have an overhead design with aluminum cups and large soft ear cushions, a digital-to-analog converter is built on a Realtek ALC4050 chip .
The model has a projected retail price of $800 , while co-funders can order the Écoute for $450 for January 2024 delivery.
