OLLO Audio S5X 1.1 Calibrated

OLLO Audio S5X 1.1 Calibrated - Reference-Class dynamic headphones, with an open back and flat frequency response, ideal for binaural/immersive mixing and USC calibration that enhances the response to flat frequencies from ~2dB to ~1dB tolerance using DSP. Product made in the EU.

Driver/Speaker:

• Hand-selected transducers matched left/right that provide precision and instrument separation. (SPL tolerance of +/-1dB, pink noise, range 100Hz-10kHz in free field*)
• 50 mm, PET diaphragm 25u, 2-layer coil, 50 ohms,
• Neodymium dynamic speaker, with 108dBSPL @ 0 dBu RMS 1KHz 30 ohm output that makes them work with smart devices.
• Replaceable with household tools.

Acoustics:

• Replaceable ear cushions with an outer diameter of 95 mm (3.75 inches), an inner diameter of 57.5 mm (2.25 inches) and a depth of 20 mm (0.8 inches), +/-2.55 mm.
• Artificial leather membrane, hybrid, perforated and velvet pads to eliminate leaking around the headphone seal, resulting in a smoother response across all frequency bands and improved warmth dispersion.
• 1kHz @ 85 dB SPL sweep THD < 0.074%, Frequency response variation in the band from 20Hz to 20kHz ~12 dB SPL pink noise.
• Front-to-back air pressure equalization controlled with Saati flow resistance 3.2Ohms(²)/1cm².
• The eccentric driver, tilted in a conical radiation axis with an optimal sound stage for spatializing objects in binaural playback.
• Frequency response adjusted for translating the immersive mix between the binaural configuration and that of the speakers.

HeadBand:

• Artificial leather strap
• Clamping force set for a frequency response centred on the standard industry bitragional diameter of 14.3 cm (KEMAR)
• Stainless steel spring powder-coated
• 360-degree rotation of the ear cups, adjustable slider for head size
• The strap and steel band can be replaced with household tools

Wiring:

• Detachable braided silicone cable with OFC core to ensure minimal signal distortion.
• L and R plugs with colour labels (left is black).
• Locking mechanisms with ball on the integrated 2.5 mm jack plug
• Screwable adapter from 3.5 mm jacks to 6.3 mm jacks (1/8 to 1/4 inch)
