• Perforated hybrid artificial leather and velour earpads to control flow resistance around the earpads seal resulting in smoother response through all frequency bands and improved heat dispersion.
• 1kHz @ 85dBSPL sweep THD < 0.074%, Variation in frequency response in band from 20Hz to 20kHz ~12 dB SPL* pink noise.
• Front-to-back air pressure equalization controlled with Saati flow resistor 3.2Ohms(²)/1cm²
• The ex-centric and angled speaker in a conical radiation chassis with an optimal sound stage for the spatialization of objects in the binaural renderer
• Frequency response tuned for translation of immersive mix between binaural and speaker setup

HEADBAND

• Artificial leather strap
• Clamping force set for target frequency response on industry-standard bitragional diameter of 14.3cm (KEMAR)

• 360 earcups rotation with sliders for head size adjustments
• Strap and steel headband are replaceable using home tools

CABLE

• Detachable braided silicone cable employing OFC core to ensure minimal signal distortion.
• Colour labelled L and R jacks (Left is Black)
• Ball-locking mechanics on the embedded 2.5mm jack plug
• Screw-on adapter from 3.5mm to 6.3mm jacks (1/8 to 1/4 inch)

CALIBRATION PLUGIN USC
Unit Specific Calibration plugin included. AU and VST3. Upgrading with the Waves NX room modelling and head tracking available.

WARRANTY

FLAT OUT OF THE BOX...

...is the phrase reviewers coined for the S4X. Their neutral and honest sound signature was perfected in close R&D collaboration with professional mixing and mastering engineers. The new 1.3 version now includes USC calibration to push that even further.

Studio reference class, open back, dynamic headphones with flat frequency response and USC calibration, 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, 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 an outer diameter of 90 mm(3.5inch), an inner diameter of 55mm(2.2inch) and a 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 a 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)
