Ollo Audio S5X 1.0 Reference Headphones for Binaural and Immersive Mixing


3 items left

 

Designed and optimised for binaural mix translation between headphones and speaker setup.

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

BAD MONITORING STEALS YOUR MIX TRANSLATION! *

*Most studios do not have a truly flat frequency response. They have modal dips and peaks that even software can't even out.

The S5X fixes this with room independence and flat tuning, allowing your monitoring to rival the flattest studios in the world.

Trusted by professionals working with Adele, U2, Ed Sheeran, SIA, Rihanna, Sting, Foo Fighters, Beyonce, etc.

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,

Ollo Audio S5X, Amazing headphones

Very neutral to my ears with incredible dynamics and detail. I have around a dozen headphones, several headphone amps and dacs, I’m retired so spend a lot of time listening to music. For a start, I like unusual looking headphones and the Ollo are that, reasonably comfortable but people with big ears might have a bit of a problem as the earpads are round and internal diameter maybe a touch small but on the whole I find them 8/10 for comfort. I would call them musical but quite detailed and very dynamic. Bass is powerful but not overpowering in any way. I don’t normally listen to playlists but I happened on a qobuz playlist with on of the songs being an original movie picture soundtrack, Blindness, Trilobita solo 2 Uakiti. This track alone demonstrated very clearly the dynamics that none of my other headphones could match. These headphones are unforgiving of bad recordings but on well recorded music they are exceptional.
