"Ollo’s HPS S4X mixing headphones are incredible. Their linear frequency response allows me to hear every detail in a mix. They even fill that low-end gap I’ve known from other open-back headphones. So it's way easier to mix bass and kicks. Their neutral sound is supplemented by their equally natural design. Ollo didn't use any plastic. The ear cups are made of walnut wood and even the headband is made of real leather. The S4X has really enhanced my studio gear and improved my mixing workflow."

OLLO vs. Sennheiser vs. Audeze vs. AKG vs. Beyerdynamics vs. Audio Technica
We measured and compare the frequency responses of the main mixing headphones on the market. Measurements were made using G.R.A.S 45CC using IEC 60318-1 ear simulator and Dewesoft AD conversion Sirius system.
