Axel Grell is a legend in the audio world. He's a German headphone designer and acoustic engineer who created some of the most beloved audiophile headphones still used today. The 1997 Sennheiser HD 600 is still the gold standard for a natural-sounding midrange. The HD 650 (a warmer HD 600), the HE 1 (a mere $60,000 to you) and the HD 800 S (famous for its soundstage) all have his fingerprints on them. So when Axel makes a headphone, you pay attention. Today the Grell OAE2 goes on sale, and I've been testing a pair for the last two weeks.
