In this video I’m revisiting the OLLO Audio X1 after weeks of real-world use—actual mix sessions, lots of reference tracks, and a bunch of A/B comparisons—because I finally feel like I “get” what the X1 is. I brought a few producer/engineer friends over to get honest impressions, and the common theme was the same thing I’ve been hearing: the X1 is brutally transparent, confidence-inspiring neutral, and it stays clear even at low volume. Comfort and build are strong (the wood cups look great), and the sound is basically a microscope for mix decisions—reverb tails, delays, compression artifacts, and midrange balance show up immediately. On my end, I ditched the USC2 plugin from the chain. The UI felt clunky, the Harman target in-app made the X1 darker than I like, and I’m just not a fan of software-based calibration when I can avoid it. Instead, I loaded the individual calibration file into my RME ADI-2 FS R Black Edition and did what I normally do: a small bass lift (about +2.5 dB around 60 Hz, wide). The X1 takes EQ extremely well—still natural, still detailed, and never bloated. I also compare it directly to the Audio-Technica R70xa (and touch on the DCA Aeon X and LCD-X). My takeaway: X1 is the better dedicated mixing tool—neutral, fast to work on, and uncolored. The R70xa feels more open and spacious with more “performer” energy, and it can cover mix/master duties if you EQ it right, but for pure mix accuracy, I’d still grab the X1 first.
