"I purchased the OLLO S4 and S4R early 2019, I was blown away by how good the frequency response was In both and how well the sound translated between the S4 open back to the S4R closed back. For me, using open-back headphones was a first when I purchased the S4 headphones and since doing so I’ve been confident about mixing completely In the headphones and trust it’s going to translate just as well across many systems."
