Premium closed-back headphones that deliver superior acoustic performance, comfort, and durability to professional engineers, musicians, and audiophiles alike. They utilize 40mm neodymium drivers for an expansive soundstage with clear, extended highs and warm bass. The drivers further use diaphragms developed with APTIV Film for improved linearity and lower THD (total harmonic distortion). Closed-back, circumaural design of the headphones rests comfortably over the ears and reduces background noise. Their lightweight construction features aircraft-grade aluminium alloy yoke and carbon fibre cap for enhanced durability. Steel driver frame with vented centre pole piece improves linearity and eliminates internal resonance for consistent performance at all listening levels, while the ergonomic dual-frame, padded headband is lightweight and fully adjustable for hours of listening comfort. The headphones also feature Alcantara ear pads for maximum sound isolation and comfort and the 1.8m long dual-exit, detachable oxygen-free copper cable (OFC) with Kevlar reinforced jacket and gold-plated MMCX connector (3.5mm stereo mini jack) that offers superior performance and durability. The included storage case, replacement set of Alcantara ear pads, replacement cable, and threaded adapter ensure years of uninterrupted listening enjoyment. Sensitivity: 99 dB/mW. Impedance: 46 Ohm.
