Sennheiser Ambeo Smart Headset
You’ve no doubt heard of smart speakers—and you may even own one—but have you heard of smart headphones? It’s not quite a thing just yet, but Sennheiser—the familyowned German company that has been making microphones since 1946 and invented the first on-ear, open-air headphones (the iconic HD414) in 1968—has developed an intriguing product that draws on its expertise in both areas. The Ambeo Smart Headset does something no other headphones we know of can do: It captures 3D audio for videos you shoot on your phone. The idea is to record an immersive “you are there” soundtrack that makes the listener feel as though they are on location. The results can be quite convincing, but you have to wear headphones to experience it. Don’t worry, any ordinary stereo set will do.
So how’s it work? Patented omnidirectional microphones integrated into the headset’s earpieces pick up sound as your ears hear it, setting the stage for a binaural recording that replicates the spatial characteristics of the surrounding environment, directional sounds and all. Binaural recordings—made using a dummy head outfitted with microphone ears—have been around for decades, but with Ambeo, Sennheiser is applying the concept in a new and exciting way. The difference here is he who dons the Ambeo headset becomes the dummy (don’t say we didn’t warn you), only with the awesome ability to record binaurally on the fly.
To make the magic of 3D recording possible, the headset draws on three proprietary elements from Apogee: a mic preamp, precisely tuned analog-to-digital (A/D) and digital-to-analog (D/A) converters, and
Soft Limit technology that optimizes recording levels in real time to preserve dynamic detail. The headset’s inline controller has several controls, including a Smart Slider to set microphone sensitivity for Normal or Loud (think concert) and a “situational awareness” rocker with settings for ambient noise level: One fades in outside noise so you can hear what’s going on around you, the other engages active noise cancellation; the feature is defeatable and can be used when recording or making a call. Sennheiser also offers a free app that provides access to more advanced control features and customization options.
For now, the Ambeo Smart Headset works only with IOS devices—it records audio via Apple’s Lightning connector and integrates with the standard IOS camera app—but Sennheiser says an Android-compatible version is in the works.
You can experience Ambeo recordings on the “Ambeo Smart Headset” page at en-us.sennheiser.com. A series of short Urban Exploration videos recorded in cities around the world and Travel videos shot in spectacular locations such as California’s Joshua Tree National Park and the Azores off the coast of Portugal provide examples of Ambeo in action, some more convincing than others. Recordings made in the bustling cityscapes of Hong Kong, Berlin, New York, Los Angeles, and Paris are more compelling, so start there. It’s not hard to imagine a range of applications for Ambeo— from sporting events to family gatherings and vacations, all potentially more engaging with an Ambeo soundtrack.
The Sennheiser Ambeo Smart Headset sells for $300—and, in case you’re wondering, it functions perfectly fine as a normal set of earbuds. Well, not normal, but you know what
I mean.—
