How long does Profile Wireless support internal recording?
Each transmitter features 16 GB of internal storage, allowing up to approximately 30 hours of audio recording.
When Safety Mode is enabled, recording time is reduced to around 15 hours per transmitter.
The internal recording feature is especially useful in situations such as:
- Wireless signal loss
- Audio dropouts
- Camera audio input failure
- Outdoor shooting in crowded environments
- Productions requiring secure backup audio
Does Profile Wireless support 32-bit float recording?
Yes. Starting from firmware version 4.1.0, Sennheiser added support for 32-bit float recording to Profile Wireless.
This feature is highly valued by content creators and filmmakers because it helps:
- Reduce the risk of audio clipping
- Recover gain more easily in post-production
- Increase dynamic range
- Handle environments with rapidly changing sound levels
For creators shooting run-and-gun content or live events, 32-bit float recording provides significantly higher audio security.
What is Safety Mode on Sennheiser Profile Wireless?
Safety Mode allows the system to record two different gain levels simultaneously:
- One standard audio track
- One lower-gain backup track to prevent overmodulation or clipping
This helps protect audio signals during sudden volume spikes such as:
- Stage MC performances
- Outdoor interviews
- Concert vlogging
- Event productions
Does Profile Wireless support Bluetooth?
Yes. Starting from firmware version 5.0.0, the transmitters can connect directly to smartphones or PC/Mac devices via Bluetooth.
Users need to update the firmware for the entire system to enable this feature.

This is an important consideration for professional production workflows requiring multi-camera or advanced audio recorder synchronization.

The low-cut filter helps reduce:
- Wind noise
