Sennheiser intros 1-channel version of its Profile Wireless 2.4 GHz mic, adds 32-bit float recording

Designed to be lightweight and ultra-portable, the 1-channel Profile Wireless covers typical usage scenarios of solo creators, while allowing for later expansion. There's also an update to 32-bit float recording.

This is a neat little bit of product redesign that trims away all the fat on a popular wireless mic system for solo creators while leaving a clear upgrade path. The new Profile Wireless 1-channel mic system includes a clip-on mic with mini windshield and magnetic mount, a two-channel receiver, two USB cables, USB-C and Lightning adapters, a camera cable, and a shoe mount adapter. A second USB charging cable replaces the charging bar of the two-channel version launched in late 2024.

“Following the huge success of the Profile Wireless 2-channel system, we’re now catering to the solo creator, who does not require the full two-channel package but would rather like to save on weight and cost and still have Sennheiser audio quality,” says Hendrik Millauer, Product Manager Broadcast & Film at Sennheiser. “Profile Wireless 1-channel is also ideal for the casual user looking for a wireless mic to hook up to their laptop, for example.”

The system is quick and easy to set up with no app required. It can be used on cameras, with smartphones and computers, and can be combined with an external lavalier microphone or even used to create a wireless boom. The mic has an operating time of up to seven hours, and 16 GB of memory for up to 30 hours of internal recording. Anyone looking to expand to the two-channel system just needs to add a $99 Sennheiser Profile Wireless Replacement Clip-On Transmitter/Recorder.

32-bit float update for Profile Wireless

“With the latest Profile Wireless firmware update, we’re addressing user requests for a 32-bit float functionality,” adds Millauer. “This will allow creators to record with extremely high dynamic range, and help them to recover clipped audio.”

For 32-bit float recording, Profile Wireless combines the audio signals of the two A/D converters inside the Profile Wireless mics to create a single 32-bit float audio stream.

Creators who prefer 24-bit recording due to its lower memory requirement still have the option to deactivate 32-bit float recording and turn on the Safety Channel Mode. This will output a ‑6dB version of the audio in addition to the original sound level and thus help protect against clipping.
