The project was very much a personal journey for Grell: “I started at Sennheiser in 1991, when development of the original Orpheus had just finished. I had the impression that it simply wasn’t possible to make it better — it was just perfect.” Immediately, Grell and other acoustic engineers became fascinated with trying in all his work to get as close as possible to Orpheus. “As a young engineer, it was the benchmark,” he continues. “There will be some in our offices, and our engineers will always be inspired to get a little bit closer to Orpheus in whatever they happen to be designing.”
