Sennheiser Profile Wireless Introduced – All-In-One, Clip-On Microphone System
At NAB 2025, Nino caught up with Callie Blake from Sennheiser to take another look at the Profile Wireless system. Although it was released last year, the system is getting renewed attention at NAB as Sennheiser highlights their first entry into the 2-channel, 2.4 GHz wireless space. It combines dual clip-on transmitters, internal recording, and a charging bar that can also be used as a handheld mic.
We covered the Profile Wireless when it first came out, which you can read about here, but this year at NAB, Callie gave Nino a closer look at how the system works in practice. It includes two transmitters and a receiver that slot into a compact charging bar, which doubles as a handheld interview mic or can be mounted on a tripod via a thread for desktop use. Each transmitter has a built-in mic and the option to connect an external one. The receiver connects directly to phones, laptops, or cameras using the included USB-C, Lightning, or cold shoe adapters.

Internal recording and backup options
During the conversation, Callie confirmed that the Profile Wireless could be used as a standalone microphone and that each transmitter includes 16GB of internal memory, allowing for up to 30 hours of onboard recording. This internal recording acts as a backup in case of signal dropouts or interference. There’s also a safety track mode that records a second channel at lower gain, helping to avoid distortion from sudden loud sounds. Currently, the system records at 24-bit, but Callie noted that a firmware update is planned. She also pointed out that the Profile Wireless carries Sennheiser’s signature sound profile, something the company prioritized even though they weren’t first to market.
Battery and charging
Each transmitter runs for up to 7 hours on a single charge. If needed, they can also operate while plugged into power via USB-C, making longer sessions possible without interruption. The charging bar holds both transmitters and the receiver, and when fully charged, it extends overall operating time to around 15 to 18 hours in the field without access to AC power. A USB-C to USB-C charging cable is included. The charging bar extends overall battery life and can also be mounted on a tripod.

Compatibility and connectivity
The receiver connects directly to a variety of devices, including smartphones, laptops, and DSLR cameras. It comes with USB-C and Lightning adapters, as well as a cold shoe mount and a 3.5mm TRS cable, so, as Callie pointed out, there’s no need to purchase additional accessories to get started. Each transmitter includes a locking 3.5mm input for an external lavalier mic, giving users the option to combine the built-in mic with a more concealed or specific mic placement when needed.
Price and availability
The Sennheiser Profile Wireless is available now for $299 / €237.06. For more information, please see the Sennheiser website.
