studio headphones for DJ umek by OLLO Audio


Custom logo on a pair of high quality headphones is something your audience will remember


“They are beautiful, they are well built,& the sound quality is flat and true.. if these headset were a woman, I’d marry them.. lol”


With the HPS S4 headphones I decided to go all-in and mix a song from scratch using them as my only monitoring system, after I finished I sent it to the client, my mix was approved on their first listen. I’m happy to say I can trust them and use them every day.


The sound is detailed, clear and smooth without colouring the mix. This means I get an accurate idea of how my mix sounds which is crucial for a record producer.
