Sennheiser has released firmware version 5.0.0 for its Profile Wireless microphone system, introducing Bluetooth connectivity for both the one channel and two channel variants. With this update, the compact clip on microphone can pair directly with compatible mobile phones, laptops, and tablets, reducing the need for additional receivers or cabling. The system supports devices offering Bluetooth LE Audio using the LC3 codec, as well as Bluetooth Classic, providing users with greater flexibility when configuring minimalist recording setups across mobile and desktop workflows.

The free firmware update unlocks new possibilities, enabling creators to eliminate the receiver between the Profile Wireless clip-on mic and their mobile phone. This clears the smartphone connector for other usage and makes the set-up as compact as possible,” says Product Manager, Hendrik Millauer.

As usual, the clip-on mic can be fitted with an external lavalier mic, creating a very unobtrusive miking solution. Connecting an external microphone will automatically disable the built-in mic.

“For highest audio quality, the Profile Wireless receiver is a must,” shares Millauer. “LE Audio with LC3 will provide creators with good audio quality and latency for any recording where ease of use and compactness are paramount. With a Bluetooth Classic connection, broad compatibility to smart devices and laptops is given but users will have to sacrifice some of the quality that the future-proof Bluetooth LE Audio offers today.” The new firmware version v 5.0.0 can be downloaded from the Profile Wireless product page, while the online manual has been updated with information on the Bluetooth mode.
