Transducer Type: Full-range Air Motion Transformer (AMT) with Variable Velocity Transformation (VVT) and a Kapton polyimide diaphragm. Design: Open-back, over-ear, utilizing infinite baffle acoustics. Frequency Response: 10 Hz - 40 Khz. Impedance: 41 Ohms. Sensitivity / Efficiency: 89 dB / mW (Sound Pressure Level) (102 dB/V). Power Requirements: Minimum 200 mW, recommended ≥ 1000 mW. Weight: 550 grams (without cable). Inputs/Connections: Balanced 3.5mm jacks. Materials: Carbon fiber headband structure and magnesium components. These are some of the best headphones I've heard for music, with very precise sound and details, especially for ROCK songs and FEMALE VOCALS. Price: 3600 SAR, final and non-negotiable. Installment payments are available via Tabby through the "Wafi" platform. Reason for selling: Trying out another pair of headphones. Notes: Requires an amplifier with a power of 1000mW, meaning 1 Watt. An amplifier like the TOPPING L50 is recommended at a minimum to drive them to their full potential.
