Sennheiser’s single Profile wireless mic
Posted on May 14, 2025 by Adam Duckworth
Sennheiser has launched a one-channel version of its Profile Wireless 2.4 GHz all-in-one microphone solution
The Sennheiser Profile Wireless 2.4 GHz all-in-one microphone solution is now available as a single-mic system, comes in a compact bag and includes a second USB charging cable instead of the charging bar of the two-channel version launched in late 2024.
Designed to be lightweight and ultra-portable, the one-channel version covers typical usage scenarios of solo creators, while allowing for later expansion of the system by including the same two-channel receiver as the Profile Wireless 2-channel system. Also, a 32-bit float firmware update for all Profile Wireless systems is available for download on the Sennheiser website from today.
Just like the two-channel version, the solo system is quick and easy to set up – 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.
The Profile Wireless 1-channel mic system comes in a rugged pouch that includes the clip-on microphone 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.
32-bit float update for Profile Wireless
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.
To update their Profile Wireless system to firmware version V4.1.0, creators are asked to visit www.sennheiser.com/profilewireless. Under Downloads, they will find various firmware updates for Mac and PC, with a smart tool guiding them through the update process for the receiver and transmitter(s). The first batches of the Profile Wireless 1-channel mic also need to be updated to firmware version V4.1.0.
