Design process

Explore the stages in turning an idea for an RHA product into reality.

1. Engineered in the UK

The product design team draws inspiration from the UK's rich history of invention and engineering, as well as from the wider world of industry; inspiration for RHA product has been drawn from diverse sources: from aerospace technologies to musical instruments centuries old.

2. Concept

The first priority in the product development cycle is to answer the question 'what can we do better?'. Innovation is at the core of every RHA product from the initial ideas stage; we strive to ensure RHA products features a new and better way of delivering premium listening experiences.

3. Development

Design concepts are brought to life using modelling clay, to get an idea for how they will look and feel, before detailed CAD drawings are produced for initial prototyping via 3D printing. Simultaneously, technological concepts are prototyped for feasibility using design concepts to inform choices. Both design and technology concepts are continually assessed, refined and - if necessary - eliminated until they are ready to be tested together.

4. Refinement

Following initial testing, prototypes are created using full, consumer-grade materials. Audio and electronic components are extensively tested, tuned and recalibrated until everyone is happy with every aspect. Every RHA headphone has the driver and housing developed in tandem to ensure that they work together to create clear, accurate sound.

This process takes more time than any other stage of development. The end of this stage is a 'golden sample' - a fully functioning, and finished product from which production can be designed.

5. Production

Finally, RHA products are ready to be produced. Production often involves many stages; from the casting of metal to create durable housings, through the knurling machinery used to create the sturdy, textured terminations, to the hand-polished finished.

The production and assembly processes are exhaustively designed, practised and refined so that each finished product is of a consistent high standard.

Headphone housings

Developed simultaneously with each audio driver, RHA driver housings are engineered for comfort, durability and sonic performance.


The Aerophonic™ design of the MA Series' driver housings was created as a way to avoid unwanted reverberation and distortion as sound progresses from the driver to the ear. The design combines the sound chamber and sound pipe of the housing into a single shape, modelled on an inverted trumpet's bell. The shape enables RHA MA Series in-ear headphones to deliver high-level clarity in sound.


The S Series' aluminium alloy housings were designed to fit comfortably in any ear. The combination of the lightweight material, small size and selection of ear tips ensures that all users can achieve a secure, noise isolating fit. 

Ergonomic housings

RHA's T Series and CL1 Ceramic headphones use a curved, ergonomic housing design. A shape researched and engineered to fit the contours of the outer ear, the housings are comfortable and noise isolating. The creation of the unique shape of RHA's ergonomic housings is best achieved using complex manufacturing processes; metal and ceramic injection moulding.

Pioneering innovations

From the driver to tip storage, each component of an RHA product has been custom designed and developed.


Innovation and refinement can be found in many areas of RHA products. The product design team look at every aspect of a headphone; from the driver used to reproduce the sound to the storage for noise isolating ear tips. RHA has registered several patents pertaining to different aspects of the listening experience.
