TWS earbuds add balanced armature drivers to deliver clearer highs and a more detailed sound stage in a very small footprint. The challenge is fit: the driver must fit inside the acoustic chamber alongside the battery, antenna and electronics, while staying efficient enough for battery life.
Size and efficiency
The EWK series is our most compact family — several models weigh around 0.10 g — which leaves room for the rest of your BOM. Lower-DCR variants in the EWDK series support designs that need more output per drive voltage.
OEM integration support
We support the full integration path: acoustic sealing, tube or direct coupling, solder-pad configuration and assembly guidance. Send us your acoustic chamber volume and target response, and we will recommend the starting model for your prototype.
Start with samples
Sample evaluation is the fastest way to confirm fit and sound. Request the models below, measure them in your enclosure, and iterate with our engineers before tooling your production line.
