MDR7506

The Sony MDR-7506 is a closed-back, over-ear headphone model produced by Sony, commonly used in professional audio environments for monitoring and playback. Introduced in the early 1990s as part of Sony’s MDR line, it quickly became a staple in recording studios, broadcast facilities, and post-production due to its durability and reliable performance. The design emphasizes portability and isolation: a lightweight plastic housing with circumaural cups that seal around the ears and a single, long coiled cable.

Technical specifications commonly cited for the MDR-7506 include an impedance of 63 ohms, a frequency response of approximately 10 Hz to 20 kHz, and a sensitivity around 106 dB/mW. The headphones are typically rated for a maximum input power near 1,000 milliwatts. The weight is around 240 grams (without the cable), and the standard accessory set includes a 3.0-meter coiled cable terminated in a 3.5 mm stereo plug, with a 6.3 mm adapter.

The MDR-7506 is noted for a relatively neutral, monitor-like sound with strong high-frequency extension and good bass articulation, characteristics valued for critical listening, mixing, and mastering. Its durability and consistent performance have contributed to long-term popularity despite newer designs. The model remains widely used, often alongside related Sony monitoring headphones such as the MDR-V6.
