When B&W asked us to design their latest generation of in-ear buds our initial focus was the complexity and diversity of ears across the globe. Not just the external parts of the ear – the antihelix, the concha, the tragus and antitragus – but also the position and angle of the ear canal itself. For a company with B&W’s global reach, achieving comfort for the broadest range of users was critical.

Over a three-year research and design process, after a lot of prototypes and even more testing, we homed in on a design that became increasingly comfortable for more and more people. The result is the latest generation of Bowers & Wilkins in-ear buds; the most comfortable and finest sounding buds they have ever made.

The luxurious Pi8s draw material cues from the flagship Px8 headphones but with a polished, jewel-like touch surface surrounded by a protective metallic bezel.

From the outset, it became clear that before any actual design work was to happen, we’d need to understand a lot about ear anthropometrics and ear bud ergonomics – and all within the context of the constraints for the internal components: the driver, the battery, the electronics and critical microphone positions. We created over a hundred ergonomic prototypes and tested them with a huge number of users around the world.

Iterative refinement through hundreds of rapid prototypes: smart product design for a mass market product.

Ergonomic prototypes were tested in the ears of hundreds of users to ensure this wearable technology design was comfortable.

As the form of the earbuds matured, we developed a layered architecture to enable the engineers to optimise microphone and antenna positioning and also to allow for subtle iteration of ergonomic features like the silicone fin. Additionally, we developed a platform design; this enabled us to explore detailing, materials and finishes in order to distinguish the two ranges: the entry-level Pi6 and the premium Pi8.
