We intend to bring hearable technology to all earphones. Nain will customize our hearable technology to best suit your own brand's earphones. Earphones and headphones are not used solely for listening to music. Using the voice assistant, traffic updates, directions, messages and more can be checked simply with voice commands. Through sensors, you can constantly check on healthcare information, activity updates, etc. This technology can be applied to not just earphones, but also all other IoT devices equipped with speakers like car audio, portable speakers, etc. Cooperation between applications and the cloud will thus be indispensable.
