TECHNICAL DESCRIPTION

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, 32 ohms,
Dynamic Neodymium speaker with 109dBSPL (S4X) / 111dBSPL (S4R) 1Vrms@1KHz 30ohm output that makes them work with smart devices too.
Replaceable using home tools.

ACOUSTICS

Replaceable earpads with outer diameter of 90 mm(3.5inch), inner diameter of 55mm(2.2inch) and depth of 20mm(0.8inch).
Hybrid artificial leather and velour earpads to control flow resistance around the earpads seal resulting in smoother response in low mids and mids (150Hz-1kHz) perceived as natural timbre on vocals, pianos, strings,...
1kHz @ 85dBSPL sweep THD < 0.084%S4X / 0.079%S4R , Variation in frequency response in band from 20Hz to 20kHz ~13,7 dB SPL S4X / 10,0dB SPL S4R, pink noise IEC 60318-1 compatible standard.
Fully separated front and back of the speaker for minimal phase cancellation and more direct sound signature. SoundSeal™ 

HEADBAND

Self-adjusting artificial leather strap
Clamping force set for most neutral frequency response on industry standard bitragional diameter of 14.3cm (KEMAR)
