Sennheiser HD6XX
The 300-ohm dynamic drivers deliver a neutral 10Hz–41kHz frequency response with under 0.05% THD, matching the HD 650’s reference tuning prized in studios. A detachable 6-foot cable with a 3.5mm plug improves desktop and mobile device compatibility over the original design. This open-back headphone is best for mixing engineers and audiophiles who need an uncolored, analytical sound signature for critical listening sessions.
