The Sennheiser Profile Wireless is a creator’s multitool for high-quality audio. It is a solution for freelance filmmakers, videographers, and content creators. This all-in-one system includes a 2-channel 2.4 GHz receiver, two clip-on microphones, accessories, a charging bar, and a carrying pouch for USD $299.
- Up to 245 m wireless range
- 30 hours of internal recording (24 Bit/48 kHz)
- 78.5dB (A) signal-to-noise ratio
- Backup recording function activated when signal is weak or link is disturbed
- Lockable lavalier connector
- Dedicated headphone output on receiver
The Profile Wireless boasts 7+ hours of runtime and 15+ hours of usable runtime with the charging bar—which also doubles as a handheld microphone. This is the first and only 2.4GHz system with an integrated handheld option; other systems have a charging case only and cannot be used while charging. The setup is quick and easy, with no app required, and Profile Wireless is compatible with a wide range of cameras and smart devices; plus with the 3.5mm locking connector on the transmitter, you can use a Lavalier microphone.
The Sennheiser Profile Wireless has unique stand mounts on all components (mics, receiver, charging bar), which opens up diverse use cases that others do not. Additionally, this is the only system with a gyro sensor that, when activated, will turn through 180 degrees. This ensures the receiver can be read equally well, whether fixed to a mobile phone or a camera.

Charging Bar
The multifunctional charging bar is the heart of Profile Wireless. It stores and charges the system’s key components and doubles as a handheld or desktop mic with the transmitters inside and charging.
The charging bar safely holds a two-channel mini-receiver with an OLED touch display, two pre-paired clip-on microphones that automatically connect to the receiver, a 3.5 mm jack coiled cable for camera use, a USB-C to USB-C charging cable, magnetic clips for attaching the mics to delicate clothing, adaptors for connecting the receiver to mobile phones or a camera cold shoe mount, and windshields for the clip-on mics and the charging bar.
Charging Bar Specifications

- Charging time (0–100%): < 2 h
- Battery capacity: 350 mAh / 1295 mWh
- Dimensions: 45 x 42 x 19 mm
- Weight: 30 g
Clip-on mic
Three clever functions in Profile Wireless help users get audio even under challenging conditions. Each clip-on microphone has 16 GB memory for internal recording. When the Backup Recording Mode is activated, internal recording will be automatically turned on if the wireless signal becomes too weak. Also, a Safety Channel Mode outputs and records backup audio at a lower volume to help protect against clipping. This reduces the risk of clipped audio and maximizes the capsule’s usable dynamic range.
The range is up to 245 m in line of sight and up to 150 m in line of sight when body blocking is taken into account.

- Charging time (0–100%): < 1.5 h
- Battery capacity: 280 mAh / 1036 mWh
- Dimensions: 42 x 33 x 21 mm (including clip)
- Weight: 27 g
The 2.4 GHz wireless system space is crowded, and the Sennheiser Profile Wireless system brings some unique ideas to the table. It’s also priced well at $299 USD. I have found these systems very handy, especially with smaller hybrid camera setups and when long distances are not required. The handheld mic configuration is interesting and very unconventional, but the options are good.
