"Ollo's S4X headphones have revolutionised the way I approach my mixes. As someone who spends 90% of their time mixing on headphones, these offer an incredibly accurate, flat response and they are the coolest looking headphones I've ever had! Not to mention that they are still a comfortable fit after a long session in the studio. I'd be lost without them!"
