"The Ollo S4x headphones are an experience. From the moment I put them on I gently packed my previous (close-backed) headphones up and will only be pulling them out for recording from now on. I had been researching flat mixing headphones for a few months, and was reminded of Ollo's company after it popped up numerous times online via YouTube reviews as well as having them recommended by a few respected mix and master engineers across the globe. I spoke back and forth with Rok a few times for more information and both the service and shipping time were excellent. I love how each component is easily replaced and that the headset itself has an individually measured GRAS frequency response. Using REW software and the included measurement file, I was able to make an impulse response of my specific pair and create a correctional EQ curve. With just a small percentage of it I have now been able to achieve much more translatable mixes, in less time. I can't wait for my ears to unlearn my old, coloured pair and embrace this flatter, mature headphone. As for the sound, it has a healthy low end but not overpowering. The midrange is astoundingly flat. There are a couple notches in the high mids, near the 2k and 7k ranges, which I have corrected with EQ but only slightly, as those areas tend to resonate due to the structure of the human ear. The imaging is wide open, with a three-dimensional "reach out and touch" placement of effects and instrumentation, especially in the mids. The low end reaches so far that I found rumble in one of my tracks that I previously thought was completely clean. All in all, they are my favourite headphone so far."
