Sennheiser Profile Wireless mic system: 'the creator’s audio multitool'?

Sennheiser reckons that Profile Wireless, a 2-channel, 2.4 GHz all-in-one microphone system, provides videographers with everything they need to effortlessly capture high-quality audio.

Low-cost, adaptable systems that can be configured for a range of different scenarios out of the box are justly popular with content creators, and Sennheiser's new Profile Wireless kit, which will retail for $299 when it launches next month, fits the description perfectly.

The top line summary is that it's a two-channel, 2.4 GHz wireless microphone system that connects to mobile phones, cameras or computers, and can be used as a clip-on mic, handheld mic or table-top microphone – whatever the situation demands.

It's got some neat design to it too. It's centred around a charging bar that both stores and charges the key components of the system. It also doubles as a handheld or desktop mic.

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, magnetic clips for attaching the mics to delicate clothing, and adaptors for connecting the receiver to mobile phones or a camera cold shoe mount. The bag also contains a 3.5 mm jack coiled cable for camera use, a USB-C to USB-C charging cable, and windshields for the clip-on mics and charging bar.

There are adaptors to ensure the receiver can connect to the filming device of choice, allowing the creator to monitor the audio via a dedicated headphone output. The mini-mics of the system simply clip to the clothing or can be attached using the included magnetic mounts.

When a mobile phone is used for capturing video, the Profile Wireless receiver is connected with the included Lightning or mini-USB adaptor. Thanks to a gyro-sensor, the receiver display automatically rotates by 180° to remain clearly legible. Which is a neat touch.

Each of the clip-on mics has 16 GB memory for internal recording at 24-bit. When the creator activates Backup Recording Mode, internal recording will be automatically turned on if the wireless signal should become too weak. A Safety Channel Mode outputs and records backup audio at a lower volume to help protect against clipping.

Range is up to 245 m in line of sight, and up to 150 m line of sight when taking body blocking into account. ​

Pricing and availability ​

​​​Profile Wireless can be pre-ordered from 30 October and will start shipping in Q4/2024 and Q1/2025. The system retails at $299, €299, and £259 respectively.
