Mark Levinson is best known for its audiophile-quality amps and turntables. It's now getting into the wireless audio space with the No. 5909 Headphones. 40mm Beryllium-coated drivers deliver detailed, Hi-Res Audio-certified sound, with 24-bit/96kHz-compatible circuitry and Bluetooth 5.1 with LDAC, AAC, and aptX Adaptive support. A four-mic array works to provide a clear two-way audio experience, and Adaptive Active Noise Cancellation drowns out unwanted background noise when wanted and lets ambient sound in when needed. Winner of a 2021 Red Dot design award, they run for up to 30 hours per charge with ANC on and arrive with a hard-shell travel case as well as an assortment of adapters and accessories.
