Holmberg

What Holmberg does

Holmberg GmbH & Co. KG, operating under the HOLMCO brand, is a third-generation family-owned German manufacturer of professional electroacoustic devices headquartered in Berlin since its founding in 1919. The company designs, develops, and produces dynamic transducers, microphones, headsets (Hörsprechgarnituren), and hand-held communication apparatus at a single Berlin facility employing 200 staff, with all production occurring in-house under a "Made in Germany" model. Its product portfolio spans single- and double-sided headsets, gooseneck and console microphones, handheld microphones, call stations, and push-to-talk accessories engineered for high-noise, demanding environments with ambient noise cancellation and durability up to 115 dB. Specialized variants address safety-critical use cases: saltwater-resistant maritime devices, explosion-proof (ATEX) equipment for hazardous areas, and EASA-certified aviation headsets meeting ETSO-139a standards.

The company monetizes through three primary revenue streams: hardware sales of electroacoustic products, customized tailor-made solutions priced via quote, and recurring product support and repair services delivered through a global network of repair stations and distributors. Pricing is project-based and not publicly disclosed, consistent with enterprise B2B sales of mission-critical equipment. Customers are organized across six primary verticals: aviation, defense, ships and navy, BOS (fire, rescue, civil protection), public transport and rail (ÖPNV/Bahn), and control centers (Leitstellen). Distribution combines direct enterprise sales via inquiry and quote requests, a global distributor and repair-station network, listings on Mouser and DigiKey for online access, and system integration partnerships with eurofunk and Selectric for control center solutions. Industry association memberships (BDLI, PMeV, Fachverband Leitstellen) support market presence across Germany and 18 other European countries.

Holmberg's competitive position rests on a portfolio of regulatory certifications (EASA Part 21G manufacturing, EASA Part 145 maintenance, ETSO-139a, ATEX EU 2014/34/EU, EN ISO 9100, EN 50155) that create significant barriers in aviation, hazardous, and rail applications. Sustainability credentials include DIN EN ISO 14001 (established 2019), EcoVadis Silver 2025, and Science Based Targets initiative (SBTi) commitment. Recent strategic activity centers on the 2026 launch of the KRYPTON II next-generation headset for control centers and a 2025 expansion of SCORPION helmet compatibility for firefighter markets. No funding rounds, M&A activity, or external institutional ownership are evidenced; the company remains under continuous family stewardship since 1951.

Core offering

Holmberg develops and manufactures professional electroacoustic devices — dynamic transducers, microphones, headsets (Hörsprechgarnituren), hand-held apparatus, call stations, and push-to-talk accessories — entirely at its Berlin facility. The portfolio serves aviation, defense, maritime, public safety (BOS), public transport/rail, and control-center customers requiring certified, ruggedized communication hardware for high-noise and safety-critical environments.

Product overview

Holmberg develops and manufactures electroacoustic devices for professional use in demanding conditions. The product portfolio centers on dynamic transducers, microphones (handheld, gooseneck, wall-mount, and console), headsets (single-sided and double-sided with various noise attenuation levels), and hand apparatus for two-way communication. The KRYPTON II represents the next-generation headset for control center applications. Products serve aviation, defense, ships and navy, public safety (BOS), public transport and rail, and control center markets. All development and production occur at the Berlin facility. The accessory lineup includes push-to-talk buttons (ASP-76/ASP-77 for outdoor use, ASP-04/ASP-05 foot switches), microphone mounts (AFM Series), and replacement cushions. The HL-09 SCORPION helmet headset provides audio integration with firefighter and rescue helmets. The MW-58 offers explosion-proof protection for hazardous areas.
