Review: Sennheiser Profile Wireless 2-channel microphone system

Sennheiser Profile Wireless
Words by Lewis Noke Edwards

Capturing high quality audio on the go can be a real challenge, especially on the ground when attending events as a content creator or as a musician on the go.

Sennheiser understand the plight of top-knotch audio, and the Profile Wireless is a move towards great quality audio wherever you are, and more portable than ever. The Profile Wireless is an all-in-one portable solution, allowing for world-class quality sound from a surprisingly compact and robust unit. The unit can now feature 32-bit float audio via an update, effectively removing the risk of distortion and allowing for crystal clear audio no matter the scenario. While it’s not generally advisable to ‘fix-it-in-post’, 32-bit float gives you the freedom for a huge amount of post processing, both loud and quiet signals being entirely treatable after the fact thanks to the huge dynamic range.

32-bit float

32-bit float expands the traditional digital recording limits of 24-bit, effectively preventing any risk of distortion at high levels, but pushing down the noise floor so far that even low level sources are still entirely audible and, best of all, fixable in post! From whispers to motorbike engines, 32-bit float provides crisp audio with high dynamic range to ensure it’s concise and audible.

The Sennheiser Profile Wireless set includes two clip-on mic transmitters and a receiver, as well as accessories for transporting, mounting and protecting your unit. I had the unit up and recording in moments, quickly figuring out that I could lock the screen to prevent making adjustments while recording, as well as easily access to adapters and connection options. A few quick presses of some latches and I had some unassuming transmitters and a receiver in hand, easily connectable to whatever gear I have to record with! Clear metering is very helpful (even in sunlight, an area a lot of small screens fall apart in), as well as clear indicators of recording status and battery life.

Seven hours of battery life is available, the transmitter and receiver themselves connecting without the need for an app— just start rolling. Connect to a camera, computer or phone, whatever is convenient, the transmitters themselves featuring 16GB of internal storage available for recording, approx. 30 hours of internal recording.

For those after an even more cost effective and mobile solution, Sennheiser also offer a 1-channel version of the Profile Wireless. The same portability is available for solo creators or those who just need to record one signal; the 1-Channel Profile Wireless features the same connectivity and innovation, including the 32-bit float update, while also being able to be integrated into a larger system in the future if needed.

In use, the Profile Wireless system is a breeze, perfect for creators of all kinds, from music influencers to vloggers and journalists to songwriters and content creators. As creators will know, separate systems for recording and audio can yield off-kilter results when not sync’d properly, and so an all-in-one option can be the solution. The Sennheiser Profile Wireless receiver can connect easily to a phone, for example, allowing you to shoot high quality video with perfectly sync’d audio via the Profile Wireless Transmitter at your source, the high quality audio allowing for dynamics and clarity to shine through. Versatility is the name of the game with the Profile Wireless though, being a viable option for many types of audio capture. What’s more, the Profile Wireless’ charging bar doubles as a handheld option, its size and design makes it the first to offer a handheld option without the need for additional handles and accessories.

Adjusting gain, headphones and more are easily available on the transmitters and receivers, for easy use and ensuring you’re up and running quickly. Each transmitter also features an additional input for lavalier connection via a TRS connection if you’d prefer, for a more subdued visual!

Small but feature heavy additions to the Profile Wireless are what make it so special, the clip-on mics/transmitters themselves having recording capabilities for back-up audio, as well as small handy features like the screens re-orienting depending how they’re being held so you’re always looking at them the right way up. Safety Channel mode also records duplicate inputs, one at -6dB, so you’ll have a backup file if you discover your main recording has clipped. The receiver also has a high-pass filter available for filtering out low end rumble like traffic noise, air conditioning and more!

Sennheiser Profile Wireless accessories

The Sennheiser Wireless includes everything you need to be up and running, the included carry pouch also making sure your Profile Wireless stays safe and dust free while travelling!

The world of content creation isn’t always about creating videos in a curated set, a lot of it can be in the field, the same as making music. Sometimes inspiration strikes at inopportune times, and high quality demos on the road or at home can really help keep the creativity flowing for a musician. Content creation at large events for either interviews or general video making can be a real challenge, but the Sennheiser’s ability to quickly transform from a handheld, battery-powered recording device to a recording medium for use with a camera is what pushes it ahead of the pack. It’s as ready for you as you need it to be, with included adapters and connection options for just about any setup. As if the existing safety net like Safety Channel mode and easily accessible gain controls weren’t enough, the addition of 32-bit float via an app makes for consistent and great sounding audio no matter happens. And you’ll bet your bottom dollar that you’ll be caught out unawares one day, unless you’ve got your Sennheiser Profile Wireless handy.
