Sennheiser Profile Wireless 1-Channel Set

The Sennheiser Profile Wireless 1-Channel Set is a premium, compact digital wireless clip-on microphone system tailored specifically for solo content creators, vloggers, and mobile journalists.

Operating on the globally license-free 2.4 GHz digital frequency spectrum, this system scales down the footprint and cost of Sennheiser’s acclaimed dual-channel Profile setup. It strips away the heavy multi-unit charging bar/handheld sleeve and replaces it with a streamlined, ultra-portable setup configured for an individual on-camera speaker.

Key Acoustic and Fail-Safe Architecture

• "No-Clip" 32-Bit Float Recording: The single clip-on microphone transmitter houses 16 GB of internal flash storage, capable of saving up to 30 hours of high-resolution backup audio. Crucially, it records in 32-bit float / 48 kHz. If your speaker suddenly screams or an unexpected noise spikes the audio, the massive dynamic range means you can perfectly recover clipped waveforms in post-production.

• Intelligent Backup Modes: The system features a Backup Recording Mode that monitors signal integrity. If the 2.4 GHz connection gets blocked by structural walls or heavy Wi-Fi traffic, the microphone automatically starts local recording on the spot.

• Dual-Channel Receiver with Room to Grow: Even though this is a 1-Channel box set, the included touchscreen receiver is natively dual-channel. If your production needs expand, you do not need to buy a whole new receiver—you can buy a standalone second Profile Wireless transmitter later and pair it instantly.

Out-of-the-Box Hardware Versatility

The system bypasses the need for proprietary control apps. Sennheiser bundles interchangeable, slide-on slot adapters directly with the receiver so you can switch your target audio host instantly:

• The DSLR/Mirrorless Setup: Slide on the cold-shoe adapter and connect the bundled 3.5mm coiled TRS-to-TRS cable directly into your camera’s microphone preamp port.

• The Mobile Smartphone Setup: Snap the USB-C or Lightning structural pins directly onto the base of the receiver to mount and feed digital audio straight into an iPhone, iPad, or Android device.

Pro-Audio Deployment Tips

⚠️ Mind the Gyro Sensor: The receiver features an integrated gyro sensor that automatically flips the display 180 degrees so it's always right-side up, regardless of how it's mounted. If you notice your screen spinning unexpectedly when handling the camera cage, you can hard-lock the display orientation into a fixed direction through the receiver’s hardware settings menu.

Lavalier Security: The 3.5mm input jack on the clip-on transmitter features a dedicated internal thread collar. If you decide to plug in an external lapel mic (like a Sennheiser ME 2), make sure to thread the locking collar down all the way to keep the line completely secure from getting yanked loose during active shoots.
