Sennheiser is keeping content creators well-equipped in the audio department with its new Profile Wireless Audio System. The system is designed to be ultracompact while maintaining the audio quality Sennheiser is known for. Connect to your camera, laptop, phone, or even use the dual-purpose charging bar as a desktop mic for ultimate versatility.
Profile Wireless is a two-channel system with dual-channel receiver that communicates to two clip-on microphone transmitters via 2.4 GHz technology from up to 803.8’ away. 3.5mm analog and USB-C digital audio outputs on the receiver allow you to connect to mirrorless cameras or mobile devices. The ecosystem offers a male USB-C adapter, Lightning adapter, and a 3.5mm TRS to TRS cable to help facilitate connectivity. Safety Channel Mode outputs audio at a selected sound level in one channel and at a lower level in the other channel to prevent distortion and clipping when in unstable audio environments. The transmitters feature 16GB of internal for backup recording if your wireless signal weakens.
One of the main features of the Profile system is the Wireless Charging Bar and Handheld Microphone Transmitter. The bar charges the receiver and transmitters simultaneously for an additional 11 hours of runtime, while also functioning as a handheld omnidirectional microphone/transmitter for street interviews and Q&A sessions. The internal battery is recharged via USB-C when depleted in under three hours.
What About 32-Bit Float Recording?
One big question people have about the new Profile Wireless system is why it doesn’t offer 32-bit float recording. According to Sennheiser, the reason 32-bit float recording was omitted is because, despite the claim that 32-bit float makes internal recordings unclippable, that isn’t entirely true. 32-bit float doesn’t prevent the mic capsule from overloading on loud noises, which will cause the recording to clip. As an alternative, Sennheiser opted for internal stereo recording to minimize the risk of audio clipping. Instead of increasing from 24- to 32-bit, Profile Wireless features stereo recording on its internal microphone that records with two different audio levels, thereby maximizing the used audio bandwidth of the microphone capsule and reducing the chance of clipped audio.
Additional accessories included in the Profile Wireless drop are a cold shoe mount which attaches the wireless receiver to your camera’s cold shoe, a clip magnet to secure a transmitter to your talent, a pouch to carry the system in, and windscreens for both the transmitter and charging bar microphones

I was so hyped until I noticed no 32-bit float internal recording—a bummer.
Hey, thanks for the comment. Sennheiser reached out to us with additional information and we've updated the article to include that so hope that helps!
And the explanation doesn't make sense. If the capsule is overloaded, how the second recording with lower level will preserve the audio. Either it is overloaded or it is not. Unless there is a second capsule tuned for higher sound volumes.
Seems bulky all around. This is a good kit IF you want to use attached lavalier microphones as it has the locking connector. If not, it seems like DJI is a better system with smaller transmitters. Or Hollyland if you don’t need internal recording. The handheld seems gimmicky to me. It looks like it just uses the omni mics of the transmitters which is not what you want in a handheld mic. I love Sennheiser, but for my purposes this is a miss.
Got to cross compare the transmitters at B&H last week and the Sennheiser TX alone came out smaller / same size as DJI. The charging bar used as a handheld could have nice applications, it just all depends.
Very cool modular design! A bit disappointing that they didn’t use the same 32-bit float recording that so many other new recorders now feature. I’m curious how the safety backup feature works, how many db’s lower is the safety track? Does it only engage the safety feature when signal is weak or does it always record the backup safety line? Very cool how it all packs up together in a charger!
Hi Ted -
The Safety Backup Recording Mode, once selected, will automatically turn on the backup recording if the wireless signal becomes weak. The safety track will be -6dB lower.
