I’m finally (yes, late) back with my review of the I\O Audio Sogno—shoutout to Shenzhen Audio for sending it in and being patient while it sat on my desk for a few months. The Sogno is I\O’s cheaper follow-up to the Vol, dropping the price from $600 to $400 with a 2DD + 6BA hybrid setup. It’s not a straight copy though: the tuning is different, and in a couple ways I actually prefer the Sogno. A big part of I\O’s whole thing is “the experience,” and the Sogno still leans hard into that. You get the same watch-style display case (cool, but huge), a full spread of ear tips (crucial for fit), and this time the tips are stored in their own little cases—which I like way more for actual long-term storage. The cable keeps the swappable plug idea but cuts bulk, and I’ll take lighter and more flexible over “impressive but chunky” every time. Sound-wise, the Sogno surprised me. It measures closer to a Harman-ish target, yet it was easier on my ears than the warmer, more V-shaped Vol at louder volumes—Vol can get a bit sibilant/peaky for me. Sogno comes off clean and above average, with snappier bass, but it can also feel a bit bland and intimate compared to Vol’s perceived width. Purely on sound, I’d still personally lean cheaper (Dusk, or my EM6L), but as a luxury-style complete package, Sogno is a solid step for I\O to reach more people.
