Our Thoughts RADAR AI

This looks like a fair ask, though not a bargain. At €280, the S4X 1.1 sits around the lower end of its original €289–€399 European pricing, while a recent excellent-condition used example was listed at €210; €230–€250 would feel more compelling, but €280 is defensible if complete and genuinely clean.

The S4X 1.1 remains a serious open-back reference headphone: unusually well-built, serviceable, and valued for an honest, controlled presentation that suits mixing as well as focused listening. The wooden construction and replaceable parts give it better long-term prospects than many studio cans, with pads and cables still available. Check that both channels stay silent-free when the cable is moved, and confirm the original cable and pads are included; otherwise, excellent condition makes this a sensible buy rather than a risky one.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Ollo Audio

OLLO Audio is a Slovenian headphone brand founded in 2015 by Rok Gulič, who developed the concept from his own experiments in tactile transducers and headphone-based studio monitoring. The company grew out of a hands-on, garage-style start and is still closely associated with that founder-led, engineering-first origin story.

Its core focus is studio headphones for mixing engineers and recording artists, rather than a broad hi-fi catalog. OLLO’s lineup has centered on over-ear monitoring headphones, with an emphasis on hand-built construction, replaceable parts, and a durable, repairable design philosophy. It is not known for amplifiers, speakers, turntables, DACs, or cables.

In the market, OLLO sits in a niche boutique position: premium in intent, but not a mass-market high-end hi-fi label. Its appeal is strongest among professional and enthusiast buyers who value neutral tuning, longevity, and practical serviceability over brand prestige or lifestyle marketing. That makes it more of a specialist studio-audio brand than a traditional home-audio heavyweight.
