Based on the overall design of the HD 600, the dynamic open air HD 650 headphones from Sennheiser combine an extremely flat frequency response (10-39,500Hz/-10dB) with natural dynamics, superior resolution and a smooth, uncolored sound.
The biggest difference comes in the new model's enhanced bass response. The HD 650 includes an upgraded cable and reduced distortion in the high frequencies, making it ideal for editing and mastering applications.
HD 650 features include:
Hand-selected, matched transducers with tight tolerances (+/1 dB)
Computer-optimized magnet systems for minimizing harmonic and intermodulation distortion
Extremely lightweight aluminum voice coils ensure accuracy and fast transient response
Neodymium ferrous magnet systems for high efficiency
