About

Berlin industrial design studio creating premium consumer electronics, audio equipment, and smart home products.

Who They Work With

Consumer-electronics and audio brands (Montblanc, Sennheiser, EPOS) needing industrial design for physical products—not digital product UX.

Engagements:Project-basedRetainer

Based on 14 documented clients · verified Jul 2026

Our Take

20+ physical product designs for Montblanc (digital writing instruments, headphones), Sennheiser/EPOS (IE 900, Momentum Series, ADAPT E1, EXPAND Vision), Vodafone (Smart V10), SunPower (Reserve 3P), and Sonoro audio systems. One project mentions UI design (Kinstalk Qin Jian S1).

Published work is overwhelmingly physical hardware—consumer electronics, audio, smart home. No visible UX research, screen-based interface design, or digital product work beyond the single Kinstalk mention.

The weaker fit is anyone needing digital product UX—the practice is physical industrial design (product, CMF, packaging), with no screen-based interface or UX-research work.

Key strengths

  • Named premium brand clients—Montblanc, Sennheiser/EPOS, Vodafone—demonstrating consistent delivery at scale
  • 20+ published hardware projects across consumer electronics, audio, and smart home categories

Good to know

  • This is an industrial design studio—virtually no digital UX or screen-based interface work is visible
  • Only one project (Kinstalk) mentions UI design—confirm digital design capability if your project requires it
