Recording headphones

• 50mm, 25u PET membrane, double wound coil, 32 ohms.
• Neodymium dynamic loudspeaker with 109dB SPL (S4X) / 111dB SPL (S4R) 1 Vrms@1KHz, 30ohm output, making them compatible with smart devices as well.
• 1kHz@85dB SPL, THD < 0.084% S4X / 0.079% S4R. Variation in frequency response in 20kHz band ~13.7dB SPL S4X / 10.0dB SPL S4R, pink noise compatible with IEC 60318-1.
• Completely separated front and back of speaker to achieve minimal phase cancellation and a more directive sound signature. SoundSeal™
