OLLO audio, just better…and here's why. Our research team dived deep into behaviour science to get a sense of what a professional mixing engineer is doing, where he is, what are his challenges when he uses headphones for mixing instead of traditional studio setup. Furthermore we worked closely with our past users to determine all the nuances in performance of our past models and the hidden potential they had. We have designed a frequency response that matches what professional users have asked us to address. In the light of transparency we went further and published comparisons on the base of frequency response between our s4x and s4r models with other industry standard models. You be the judge. If you will be intrigued with what you'll see, give them a try. We offer 30 days trial on all purchases. We agree; there's no trust in modern advertising so we urge you to research out to our endorsers and ambassadors, check their social media feeds and other reviewers’ and customers’ for what the word is about OLLO products. Hopefully, you will want to give them a try at some point. www.olloaudio.com
