HD 600 Open-Back Audiophile Headphones

Last verified June 12, 2026 by the Lifetime Picks Editorial Team

The Sennheiser HD 600 is arguably the most recommended headphone in r/headphones history, a reference open back that has stayed in production for decades because the neutral, natural tuning still holds up against far pricier rivals. The open back design gives a wide, airy soundstage that audiophiles treat as a baseline for honest listening. What makes it buy it for life is the modular construction: ear pads, headband cushion, cable, and even the drivers are user replaceable, and Sennheiser stocks the parts, so a worn HD 600 is repaired, not discarded. They are easy to drive but reward a dedicated amp. Best for at home critical listening, mixing, and anyone who values accurate sound over bass heavy fun. Open back means they leak sound and offer no isolation.
