"OLLO headphones feel like using an audio microscope! They help me find the sweet spot of every sound I record, capturing exactly what I hear without any extra processing. This clarity preserves the authenticity of each sound, which is what matters most to me."

"The OLLO headphones respect all of the depth, width, air, tight bass, space and detail that I work so hard to create in a mix. I’ve compared them with the leading competitors and OLLO's win! Excellent reference headphones for mixing and mastering. Switching between the headphones and my speakers is effortless. And they are really light in weight and comfortable for long periods of use .... and they look cool too! Job well done!"

"The real strength of the OLLO headphones is that they earn your trust. The detailed, flat response means that headphones are one less thing to worry about when making music. OLLO have done an outstanding job."

"OLLO headphones deliver consistent mixes and masters, I can't go anywhere without them. Easily my favourite headset so far."

"A main point of emphasis at our school is helping engineers and producers develop world class ears. Part of that process is helping them get an accurate listening environment in their studios, but also really accurate headphones. We've tested numerous products and options to help our students and in the end Ollo was the clear winner for us. These headphones come out of the box nearly flat and each set have individual calibration profiles that can make them perfectly flat. My personal mixes and masters have come out great while using the headphones and my students are having the same experience. This is the perfect product for people who need to mix and master on cans and a perfect solution for our students."

"I’ve always been hesitant to switch headphones once I get used to a pair, but with the X1s, there was no adjustment period. They immediately felt familiar, offering an honest, detailed representation of my mixes. Switching from my studio monitors to the X1’s feels like putting a sonic magnifying glass to the audio, revealing more detail and helping me make faster, more informed mixing decisions. Headphones are an integral part of my mixing process and I rely on them to get my mixes to translate. The X1's help me do that quicker and more confidently, providing a sense of familiarity that instantly boosts trust."

"These are the best sounding headphones I’ve ever heard… At least to my ears… Same sort of way that Alan Sides’  main monitoring systems at the Oceanway studios always just felt like an extension of my ears... as do these sexy sounding (and looking) ear pillows."

"These are my favorite headphones. They sound great and are very comfortable. I’m able to use them for long hours without listening fatigue or discomfort. They come in “closed back” for recording and “open back” for mixing duties."

"I love my OLLO headphones: they sound fantastic, are reliable and trustworthy, sit comfortably on my head and around my ears, don't give me ear-fatigue and don't press my ear onto the glasses allowing for continued and comfortable use."

"The OLLO headphones have completely revolutionized the way I listen to the sonic arrangement of a song. It’s like having a sonic microscope. The level of detail and depth they get is astonishing."

“After listening and mixing using the OLLO headphones for 2 day’s, I finally realized that I could mix using these headphones alone! Using the OLLO headphones pretty much has eliminated the need to do the "car check" for me. These headphones are flat and revealing as well as comfortable for long term use. I highly recommend them!!”
