Drivers smaller than 5mm are ideal for applications where space is limited and precision is required. Some typical uses for drivers of this size are TWS earphones and OTC hearing aids.
In these applications, the small size of the driver is crucial for fitting into compact spaces without compromising the quality of sound produced.
Ole Wolff have developed a new 4.9mm driver which is a new version of the OWR-0504T-16 driver already on the market, as well as an extremely small 4.2mm driver which enables a direct fit into the ear canal. Both drivers are still on engineering stage.
