"My OLLO audio S4 headphones have now become such an integral part in my studio workflow now.
I was particularly impressed with how much low-end presence there was whilst working at low volume, the detail all round is extremely accurate. The natural frequency response for mixing is very honest and I love how they don’t fatigue my ears when switching back to my main monitors.
The addition of the S4’s to my studio setup has made the process of mixing my first album so much more intense and exciting. Looking forward to see what lies ahead."
