High-end headphone brands have experienced several major events from before the pandemic to during it.
First, legendary Sennheiser designer Axel Grell left Sennheiser in 2019.
Axel Grell’s works include iconic Sennheiser products,
such as the Orpheus / HD650 / HD580 / HD800 series.
Soon after, Sennheiser’s consumer electronics division was sold to the Sonova Holding AG group in 2021.
Axel Grell later founded grell Audio and began developing his own new products.
His first truly independently developed flagship product is the headphone we’re unboxing today.
A collaboration between Axel Grell and the renowned US crowdfunding site DROP (formerly known as Massdrop).
