Home audio might be an old product category, but Sennheiser brought the home theater into the 21st century with its Ambeo Soundbar. For all intents and purposes, the new product can replace your surround sound system with a 5.1.4… soundbar? But how is that possible?

Who is the Sennheiser Ambeo for?

The large size of the Ambeo Soundbar means you need a large area for setup.

  • Anyone with $2500 lying around, and wants a home theater setup, but doesn’t want a ton of channels and cables lying around.
  • Home theater buffs looking to de-clutter their living room.

How do you set up the Sennheiser Ambeo Soundbar?

All of these controls are on the remote, with the exception of the NFC target.

If you’ve never set up a soundbar, the Sennheiser Ambeo Soundbar will kinda throw you for a loop, but it’s not terribly complicated. The process goes like this:

  1. Place the soundbar in a spot where the upward-firing speakers can fire sound to the ceiling without obstruction
  2. Plug in the power cord to the back of the soundbar, and then to the wall
  3. Connect your source (cable box, TV, etc.) to the soundbar. If your TV is “dumb,” be sure to connect the HDMI out cable to the proper ports
  4. Download the Sennheiser Smart Control app on Android or iOS.
  5. Use the included cable tie to manage the cords coming out of the back
  6. Calibrate the soundbar
    1. Locate where you’ll be sitting, and place the tip of the included measurement microphone where your head would be
    2. Connect the microphone to the port in the front of the soundbar
    3. Turn on the soundbar, and connect to it via the app
    4. Start the room calibration process with the app, preferably when you’re nowhere near the soundbar
  7. Add the soundbar to your Google Home account to add Chromecast functionality

The Sennheiser Ambeo Soundbar has three HDMI in ports, and one each of: HDMI output, optical input, USB, auxiliary in, ethernet, and subwoofer pre-in.

When the soundbar is calibrating, it will play a series of sweeps to help it map out the room. This helps the Sennheiser Ambeo Soundbar to not only determine how best to adjust its own performance, but also figure out how to use the room around it to create a 3D effect for surround sound content. To make sure that it works properly, the more square the room is, the better the effect will be. Also try to keep the walls between one and five meters away from the soundbar if at all possible for best results.

Smart devices will always have that extra layer of setup, but they payoff is being able to control your soundbar from your phone. Equalize, edit the 3D sound effect, or swap sources on the fly. While the Ambeo Soundbar comes with a remote, it’s much more satisfying to use the phone app.

What’s it like to use the Sennheiser Ambeo Soundbar?

As the Sennheiser Ambeo Soundbar is a very unique product, it’s tough to do justice to the experience. That’s because it goes beyond what most people know and understand when you tell them “this product is a sound bar”—because it’s really not.

The closest thing I can relate it to is that it’s a fully-functioning surround sound system, but without all the cables and extra channels lying about your room. Though we’ve seen plenty of Dolby Atmos soundbars that can kindasorta approximate the experience, Sennheiser’s Ambeo futureproofs itself by building in support for the next leap in broadcast standards: MPEG-H. We’ll get to that in a minute, but for now, just know that it’s the next generation of digital audio that enables much of the Ambeo 3D sound magic to work.

A microphone placed right where your head would be normally helps the soundbar create the 3D sound effect.

By plugging your TV, Blu-ray player, or cable box to the Ambeo Soundbar via HDMI, you’re performing the only connection you need between your media and audio hardware, though you can connect via WiFi or Bluetooth. Once everything’s connected and set up, the soundbar will attempt to “map” the room around you using the 13 speakers and a microphone that plugs into the front of the unit. Once it’s done this, it can then time out when and how to bounce sound off of your walls and back to you—creating the surround sound effect.

Much like it is with a surround-sound system, your audio content really is coming from all around you. It’s just that it’s getting to your ears by way of the room you’re in, and not a dedicated speaker physically seated behind you. The result is a convincing virtual 5.1.4 system (two left channels, two right channels, a center channel, four channels behind you, and one subwoofer) that can use Atmos, MPEG-H, and DTS:X content. As of publish, this is the only soundbar that I’ve felt truly convinced by in a practical setting, but I believe this is about to change as broadcast standards evolve.

The remote isn’t strictly necessary if you have the app, but it does add a nice touch.

When you’re listening to the Sennheiser Ambeo Soundbar, you might initially feel a little disoriented if you aren’t prepared for the surround sound effect.

What is MPEG-H?

Back in 1988, a group of companies got together and formed the Moving Picture Experts Group to help standardize how broadcast signals and media files would be transmitted. Over the years, this consortium has made the leap to digital broadcast standards, and whether you realize it or not: it’s governed the way you consume video and audio content online for as long as you can remember. MPEG-H is a continuation of their efforts, that covers standardizing 4K/UHD content. However, the real Easter egg there is MPEG-H also contains standards for 3D audio that goes beyond what was previously available.

Instead of taking your music and mashing all the tracks together into two channels (stereo), MPEG-H takes each track (instrument, vocals, synths, etc.) and adds it to the signal as individual objects. This way, each element of the recording can be altered to fit the user’s desires. Additionally, because there’s such a high limit of audio objects, a broadcast stream can handle a lot more data than it could before. For example, if you wanted to watch a soccer match, you could filter the active audio objects to make it sound like you were in the stands, right next to the pitch, or even mute the crowd altogether. Because MPEG-H is a broadcast standard, you can do all this through your TV.

While MPEG-H might not hit the US anytime soon, it’s likely that streaming services might not wait around for broadcast television to set the tone on this change. Consequently, paid subscription services may end up using this to capture cinephiles and audiophiles alike because the applications are so amazing. Sony debuted a truly flooring 3D audio platform at CES 2019, and as they have one of the largest music libraries in the world: it’s not too far-fetched to assume that this is something that will actually make it soon. If MPEG-H does come to a living room near you, you’re going to need hardware that can handle the surround sound effect to make the most of it.

That’s why the Sennheiser Ambeo is so special: it’s futureproof as far as this capability goes. It’s not a soundbar, it’s a surround sound system.

How does the Sennheiser Ambeo Soundbar sound?

This is a bittersweet kind of product for me, because the Sennheiser Ambeo Soundbar is one of those devices that doesn’t really abide by the same rules as other soundbars. Once MPEG-H and the resulting 3D audio platforms reach maturity (Deezer, Sony 3D Audio, etc.), speaker performance won’t matter as much as the personalization options. And by that time, those options will be plentiful. That’s probably the main headline here too: a revolution in personal audio is coming, and in the soundbar world—currently only the Ambeo Soundbar is futureproof enough to last you a long time.

But we tested the output to the best of our ability, anyway. Instead of our normal gated response, we had to move our testing to a typical living room setup. There are a few resonances here and there, but many of those swings in emphasis were done by the soundbar itself to combat room acoustics. Because this unit is meant to be used in a living room, we had no choice but to test it in the same kind of environment.

This is merely one calibrated result—yours will look slightly different based on room acoustics.

First item of note: when calibrated, the Sennheiser Ambeo Soundbar has really good bass response, which allows it to completely assume the role of your subwoofer. Many units struggle here because the soundbar design typically doesn’t allow much in the way of powerful sub channels. Usually, you need a larger chamber and driver for that. Luckily, the Sennheiser Ambeo Soundbar uses its size well, making for outstanding audio performance. However, if you want to tinker with the sound, the app allows for a fairly basic 4-band equalizing. There are also several presets to choose from depending on your current use.

When using 3D content like Dolby Atmos or MPEG-H audio, the illusion of surround sound is convincing, but there is a dearth of content available at the moment. For now, you’ll be leaning on Atmos-enabled content from Blu-ray movies and streams.

If you’d like an example of how this sounds, put your headphones on and watch the clip above. This was shot using only a Sennheiser Ambeo headset, a mere 2-channel microphone instead of the maximum possible 64-object MPEG-H stream. Now, imagine being able to hear that around you just like in the video, but without any speakers around you: just the soundbar in front of you. That’s the kind of thing that the Sennheiser Ambeo Soundbar can do.

Should you buy the Sennheiser Ambeo Soundbar?

Yes.

If you just read all that, the answer should be abundantly clear to you that this is no ordinary soundbar, and it’s something truly special. If you have $2,500 to spend on a home theater system and you don’t have the patience to set up a whole surround sound system: the Sennheiser Ambeo Soundbar is by far the best option on the market bar none. Not only is it the most futureproof option available, but it performs at a level unseen in the soundbar industry to date. It’s an investment that not only has staying power, but a strong return.
