I've trusted OLLO since 2019, and have moved to exclusively using my OLLO's for my mixing and mastering projects. My Tannoy monitors are collecting dust.

Customer Reviews
"My ears are smiling! Thank you!
These really are everything they claim to be!
These things are amazing!!!!!
Everything sounds just as it should!!! Bass is just about perfect. Highs are crisp but silky. This really sounds like I’ve strapped a really expensive pair of floor speakers to my head! Stereo imaging is far better than other more expensive headphones I own. These are like 3D. Already the best ear goggles I’ve ever owned.
These come with a 30 day return to try them out...I didn’t need 30 minutes!"
