Reference class, open back, dynamic headphones with flat frequency response for binaural/immersive mixing made in the EU.

SPEAKER

• Hand picked and left / right matched transducers delivering accuracy and instrument separation. (+/-1dB SPL tolerance, pink noise, range 100Hz-10kHz in free field*)
• 50 mm, PET 25u membrane, 2 layered coil, 50 ohms,
• Dynamic Neodymium speaker with 108dBSPL @ 0 dBu RMS 1KHz 30ohm output that makes them work with smart devices too.
