Speaker

• Hand-picked and left / right matched transducers delivering accuracy and instrument separation. (+/-1dB SPL tolerance, pink noise, range 100Hz-10kHz in the 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.
• Replaceable using home tools.

Acoustics

• Replaceable earpads with outer diameter of 95 mm, an inner diameter of 57.5mm and depth of 20mm, +/-2.55mm.
• 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 best translation of HRTF spatialized information in your Atmos or stereo projects

Headband

• Artificial leather strap
• Clamping force set for target frequency response on industry-standard bitragional diameter of 14.3 cm (KEMAR)
• Stainless spring steel with powder coating
• 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

Optional Calibration Plugin Usc

S5X come with an optional individual calibration Unit Specific Calibration plugin. AU and VST3. Upgrading with the Waves NX room modelling and head tracking available.

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