Premium over-ear HD headphones

TURN is a set of over-ear headphones that know how to generate deep, powerful acoustic levels. A rubberized steel headband and steel hinges create a rugged foundation for TURN.

Client: Teufel

The headphones are extremely durable and even underwent a successful drop test from a height of one meter. A large articulated dial on the left ear cup makes it easy to switch between an enhanced bass mode and neutral playback. On or off, you’ll still enjoy a balanced differentiation of all sonic elements.

The Pilotfish team developed creative concepts for the folding mechanism of the headphones. After discussions with the client, Pilotfish advanced with selected concepts and developed proof of concept prototypes of the smart folding and sound adjustment and helped the client to design a sleek yet extremely durable product. The folding mechanism now serves as the leading design feature of the Teufel headphones.

Product DNA

The purpose of the DNA phase is to understand the user, market, and technology as well as clearly outline the product definition document (PD). In addition, we conduct qualitative user research through user observations and interviews and then develop personas and user cases. Together, the PD and user-based research result in the initial product concept ideas.


Our team of engineers designs the encasement and all details for production, including draft angles, screw bosses and ribs for assembly. The engineering work is tested with working prototypes and the final deliverables are 3D files and supporting documents ready to start tooling. Pilotfish can also manage the development of the electronics with the support of our team in Taiwan.

Proof of Concept

In the POC phase, we develop the working principles and test them. All critical and unknown aspects of the product have to be understood and problems must be solved before moving onto the next phase.

Behind the Scenes

Endless sketches, foam models, and 3D-printed shape studies—these are some of the many prototypes we created while developing Teufel’s TURN headphones and its intuitive ear cushion design.
