Offered is „O 410“ by Klein + Hummel Neumann as second-hand device from the category „Active Speaker“ on audio-markt.de - the online market place for high-end. The advert with the number 3042225704 ends on 02.12.2026 at 08:42 o'clock.
This is a very ambitious ask: against your own comps, €4,900 sits far above the 75th percentile at €1,863 and roughly 10× the median €495, so it’s priced like a serious outlier rather than a normal used buy. If the seller can justify that with exceptional provenance, condition, or a matched pair, it’s one thing; otherwise, it’s hard to see this as market-clearing.
The timing matters because this is an older, established Neumann/Klein + Hummel design, so value here is about performance and rarity rather than being the newest generation. These monitors are respected for scale, precision, and a very “big” full-range presentation, so a clean example can still be a rewarding long-term buy; at this level, though, I’d want proof of originality, service history, and that all drivers and electronics are healthy before paying up.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Neumann traces its origins to Berlin, Germany, where Georg Neumann and Erich Rickmann founded the company in 1928. Initially focused on pioneering condenser microphones, such as the groundbreaking CMV 3—nicknamed "The Bottle"—Neumann quickly established itself as an innovator amid the early days of professional audio. Despite wartime disruptions that split production and led to the creation of Microtech Gefell, Georg Neumann rebuilt in post-war Berlin, launching the iconic U 47 tube-condenser microphone, which solidified the brand's legacy in recording history.
The brand specializes in professional recording equipment, renowned for its high-end condenser microphones like the U 47, U 67, and U 87, which dominate studios worldwide. Beyond mics, Neumann produces studio monitors, headphones, preamplifiers, audio interfaces such as the recent MT 48, and historically excelled in cutting lathes for mastering. This pro-audio emphasis sets it apart from consumer hi-fi categories like amplifiers, turntables, or cables.
Neumann commands an elite position in the market as the gold standard for professional recording, embodying precision engineering and unmatched fidelity prized by engineers and producers. Its products grace legendary sessions, blending vintage reverence with modern reliability, making it essential for discerning hi-fi enthusiasts seeking studio-grade accuracy rather than mid-tier or boutique consumer gear.
