Sony officially launched the ECM-W5 wireless microphones in Malaysia. The system uses and pairs two transmitters to one receiver and is able to transmit over a line-of-sight distance of 500 cubic metres, with a new design that reduces audio dropouts in congested radio-frequency environments.

One technology that facilitates this is its new Multi Interface (MI) Shoe, which is capable of transmitting 32-bit float audio, enabling audio to travel digitally and directly to compatible cameras in a single file. Moreover, the ECM-W5 also comes with up to 64GB of built-in storage, which in turn enables 32-bit float backup audio recordings, directly on the transmitter.
