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.
