Customer Ratings & Reviews

This is a great speaker. I picked this up as well as the Home 200. I placed this one in my Living Room since it is bigger, and the 200 in my home office. The 400 really fills the entire room with full, rich sound. I was very impressed with it's performance for being a relatively small speaker. But I'll take a step back for a second and mention the setup process. To set these speakers up, you need to first download the Denon Heos app. From here, it is relatively simple and the app walks you through the entire process, complete with pictures of what buttons to push, etc. From start to finish, I was done in about 5 minutes and listening to music. Using the app, you can connect to many music sertvices directly, such as Spotify, Qobuz, and more. Unfortunately, you cannot connect directly to Apple Music, which is my service of choice. However, you can use AirPlay and it works perfectly. It works just like any other AirPlay speaker and shows up in the list right in the Apple Music app. So, in my own experience, I have actually not had to use the Heos app much outside of initial setup. From what I did use and see, it seems very easy and straightforward to use. You can even use it to discover new services, radio stations, etc. Having multipole speakers, I had to try out how easy it was to move from room to room, and I was very impressed. Right in the Apple Music app, you can just select which speaker to play on and it seamlessly plays on the selected speaker(s). You can play on one or the other, or both simultaneously. It all just worked exactly as I'd hoped it would. Overall I am very impressed with the Home 400 speaker. It has fantastic sound quality, is easy to set up, and works seamlessly with other Denon speakers if you have them. Highly recommended.

The Denon Home 400 is an absolute powerhouse. Right out of the box, the setup is incredibly painless. You just download the HEOS app, find your speaker, hit the connect button on the back, and you’re ready to go in seconds. ​The sound signature is what really blew me away. Even though this is the mid-tier model in the series, it handles every genre and frequency range perfectly. You get solid bass and a great stereo feel, but the real highlight is the Dolby Atmos support. Since the speaker has up-firing drivers, I actually placed mine on top of an upper cabinet and the sound bounces off the ceiling and walls, filling the entire room even with just a single unit. It handles Hi-Res audio beautifully, too, and I’ve been loving how it sounds streaming Spotify Lossless. ​I also own the Denon Home 200, and using the app to pair the two for a true stereo experience was a breeze. As long as you create a group, they sync up instantly every time you start your music. Denon claims you can link up to 64 speakers, which is wild. I’ll probably never need that many, but the option to expand this into a full multi-room home system is a huge plus. ​Aesthetically, it fits into my home perfectly. It’s sleek and low-profile enough that it doesn’t stick out like a sore thumb; it just looks like it belongs there. ​Between the stellar audio quality and how effortlessly it talks to other Denon products, the Home 400 is a fantastic addition to any setup.

OVERALL This has an impressive build quality loaded with modern features that make it versatile in the average living room. It's visually stunning, it’s compact, lightweight, and the sleek black shell looks great on a shelf or tabletop. With a satisfactory sound level, they have the ability to fill a room with your favorite media such as music, podcasts, or movies. Setting it up is a breeze, with syncing done through Wi-Fi or Bluetooth taking seconds to pair. USAGE Aside from the speaker itself, you'll need it's companion app. The app creates groups of speakers you want your music to play from making them selectable within apps to play your audio. After pairing with my phone, I quickly realized playing music above 80% had diminishing returns. Bass falls quite flat and you're left with high mids and highs. The app acts as a type of bridge for the speakers, giving you some level of adjustment to your sound profiles. The buttons on the speakers give you some other form of control for what you're playing, but this also makes them impossible to tuck behind something or a low shelf keeping them out of sight. At this price point, a remote control could have been very useful. Unlike a few other reviewers, I never could get the speakers paired through apps meant for watching videos. Music and spoken audio had no issues but absent within apps such as Netflix, YouTube, and Hulu. CONCLUSION While build quality is quite good, and sound quality is impressive at lower levels. There's a few things that just don't justify the asking price, possibly hindered by the reliance on it's companion app. As mentioned, I never could get video streaming apps to recognize it as an output device. Largely because it bridges through the companion app and never shows up as a Bluetooth device in Android settings. That said, this is worth 4-stars.

The Denon HOME 400 is a great speaker that produces quality sound extending beyond its compact form factor. The downside is an app that makes setup, use, and customization cumbersome and frustrating. The overall build quality is excellent. This is a solid device that is well-made and looks great, easily blending into its surroundings. The physical buttons have a nice feel to them, the cloth speaker covering is taught and visually appealing, and there are no cheap or flimsy connections or components. As I alluded to earlier, setup is a bit frustrating due to the highly unreliable app. I used the HEOS app on both an iPhone 17 Pro and a Samsung Galaxy Z Fold 7, receiving the same lackluster experience on both. For starters, getting the app to locate the speaker took multiple attempts. Each time I would verify the correct Wi-Fi channel, verify the speaker was in pairing mode, the app would spend several seconds searching for the device, and then I would receive a device not found message. Once the app finally connected I was disappointed in the minimal changes and customization available. The frustration has continued because each and every time I have opened the app after not using it for a day, my devices are not found and the whole setup process begins again. So not only is the app a pain to use, it is incredibly unreliable and repeatedly "loses" my speakers (I also have the Denon 200). Now you are able to pair two speakers together, and I did manage to accomplish this. However, as mentioned, the app repeatedly failed to find my devices and forced setup again and again. While I had the two speakers paired I will say the sound is excellent. They definitely produce an immersive sound and great listening experience. Unfortunately, this experience is not one I can continue to partake in due to my app experiences. Directly connecting via Bluetooth, without using the HEOS app, has proven very stable and reliable. With both previously mentioned phones I have had zero dropped connections. This also allows me to use any streaming service, not just the native services in the HEOS app. I also connected this speaker to my TV. I did have to go into the TV settings to adjust the delay since initially there was a slight delay between the audio and video. Once adjusted, it has been a fantastic experience. Something else I noticed is the standby experience. There are two options at setup, one for the speaker to go into standby / energy saving mode, and the other for the speaker to never enter standby mode. Initially I set the Denon 400 to go into standby mode, however, getting it to come out of standby mode was futile. I always had to unplug then plug it back in. I ended up just leaving it in always on mode. Overall, this speaker is well designed and well made, producing excellent room filling sound and a pleasurable listening experience. The app experience is frustrating, unreliable, and absolutely dilutes the overall experience. The only saving grace is the direct Bluetooth connection. Denon, you have to fix the app! I would recommend this speaker, but only after making sure to explain the app problems and insuring the end user is good with a direct BT connection.

The Audio quality and hardware are amazing, but the software is challenged. So this really is a 5 star for the hardware, and 1 star for the software. But since you can use the speaker without the software, and software can be fixed... instead of a 3, this is a 4. Let's start with the really good. The physical appearance of these speaker is stunning. A lot of attention to detail (except one small thing, but you can fix it). The soft material is tight, and the light in the front is not too much (can be turned off too). Easy to access buttons, and this piece will be fantastic in most rooms. This is the larger size speaker, so this will be for your main rooms, or basement. May be a bit big for bedrooms or offices.. The small detail, for me.. the actual cord/plug. Should have been a 90 degree plug, so that it can be plugged into tight spaces. Easy fix with an adapter, or replacing the cord since it is a standard connector into the speaker. No bulky adapters (YAH!) Setup with the HEOS app, was pretty straight forward after you setup your account. Walks you through the few steps to get it connected to your WiFi network. So, first nit-pick... it doesnt' allow you to chose your WiFi network with the setup wizard, it takes what ever network your phone is connected to. You can change this later, after you set it up... but know this when you are setting up if you have multiple networks. Also there is a LONG pause after the setup. the Software does tell you it can take 3 minutes (very specific). But there is no progress indicator or anything. It also doesn't directly prompt you to update the firmware of the speaker, that happens the next time you go into the application (which again, the setup process should handle that). Now for the REALLY good.. the audio is stellar. Really Really good. If there is any nit-pick, is the base may be too much at default and you have to tweak it down. I tested 2 different streaming services (setup from the app), I tried two apps from my phone (using Airplay). Also connected bluetooth to a record player. All audio sources were really really good. Love the audio, love that I don't need a separate sub-woofer... spectacular. I also added a Home 200 series speaker as well to the network. This is when things really got interesting (both good and bad). Using Airplay, I was seamlessly able to send my audio from my phone to both Denon speakers, as well as a couple others that I have on the network... and the audio was PERFECTLY insync. And that is great, when you are trying to create that whole home audio experience. When focusing on just the Denon speakers, I could use the HEOS app, and create a group so that I can send the selected audio to both of them... again, perfectly in sync. This can become a very powerful feature if I had 4,5,6, 10 Denon items, which I may in the future... as you can then create zones and groupings, very easily. So here are some of the flaws here.. It took a while for me to find the area to do the grouping (and I do mobile apps professionally, hence a lot of my criticism here). The icon wasn't appearing, I had to quit the app, and come back, and then find it in the bottom bar. It wasn't in any of the menus. The grouping I created, disappeared the next time I came back into the app... not sure if that was a glitch or a bug, or design.. but it was gone. Adding Audio services... I was able to add Sirius and Amazon.. but there were a lot of glitches.. Amazon look like it failed, but it in fact did work and was added. I still can not get iHeartRadio to add, despite me checking everything. The HEOS software is using its own portal to authenticate, not the iHeartRadio. There is no support for Apple Music or Audacy. To use either of those, I have to use Airplay, and use the iOS app. There is a warning when adding music services, that it could slow down the main page and loading, as it is attempting to pull your favorites and show you a dashboard. There are other ways this could be solved, that would not impact the dashboard. So far, I don't see a lot of slowness, but can see where it will happen... especially if they start to add more support for other services. Volume... so my two speakers were at different audio volumes (due to my trying things out). When I group them... it was "more than simple" to figure out how to change the volume on them independently. As if I was in group mode, the volume buttons on my phone, changed them both at the same time... took a moment to identify how to change each one solo. Now for my biggest issue, and for me it is almost border line return till fixed (I am not), as I hope this can be addressed. Previous models of Denon speakers has direct native support for Alexa. So a google search, actually was saying it was supported on the 400. (obviously this is where Google AI is failing). After trying to setup for over 2 hours (installing skills, thinking I solved it, and finding out no).. .Redit thread finally told me that it was dropped in this model. So the listing that "Virtual Assistants" are supported... right now that just means Siri. Which I can't readily use, as I have too many devices that respond to "Siri". Not being able to talk to the speaker to start playing music, is actually a challenge for our home. As everyone now has to have the app installed, and then take out the phone, start the music, etc.. For over 5 years, we just speak to our smart home and we can play music. Yes, this is a "first world" issue, but this is a "first world" speaker. Since I know this can be fixed via software, I hope this can be fixed... really really quickly. Overall.. This is a fantastic speaker, really good.. But the software... needs a lot of help.

If you’re looking at the Denon Home 200 and 400 speakers, the first thing you notice right out of the box is just how premium they feel. The build quality is legit—soft-touch finish on the top and bottom, a really clean, high-end grille, and a solid weight that makes them feel like serious pieces of equipment, not just another wireless speaker. Denon definitely nailed the design and materials here. The Denon 200 is a nice size cylindrical design and the Denon 400 is essentially two of the 200s molded into one speaker design. Getting started is mostly straightforward. Plug them in and they power right up with a subtle light strip at the bottom showing status. From there, you download the HEOS app and follow the setup. QR codes in the quick start guide make it easy to jump in. If you don’t already have a HEOS account, creating one is quick, and the app does a good job finding the speakers on your network. That said, setup wasn’t perfect for me. The first attempt completely failed right at the Bluetooth/network connection step—even though everything looked connected on my end. I ended up restarting the speakers and trying again, and the second time was smooth. Everything connected instantly and showed up in the HEOS app without issues. Apple HomeKit, though, was another story. I couldn’t get them to show up there at all. Quick heads up if you’re in the Apple ecosystem: you can’t add these directly into Apple Home unless you have a HomePod or HomePod mini acting as a hub. Even with an Apple TV 4K, they wouldn’t show up for me. So while they support AirPlay 2, full Home integration isn’t as seamless as you might expect. Now to the part that really matters—sound. The sound quality on the Denon Home 200 and 400 is… a bit of a rollercoaster. When everything is dialed in—placement, EQ settings in the HEOS app, and the right type of music—they can sound outstanding. There’s great clarity in the mids and highs, and you can really pick apart different layers in a track. But getting there takes work. Out of the box, I was honestly underwhelmed. The speakers leaned heavily toward the mids and highs, which came across a little harsh, while the low end felt lacking—even with the bass turned up. At times, the bass sounded muddy instead of punchy, and it didn’t have that depth I expected, especially compared to similar Sonos speakers I’ve used (even smaller ones). After spending time tweaking settings and physically moving the speakers around, things improved a lot. Once I found the right placement relative to where I was sitting, the sound opened up. The bass became cleaner (though still not class-leading), and the overall balance felt much better. At higher volumes, they do a solid job filling a room. The app lets you dial in the spatial audio configuration, which is nice. You can dial in different parameters for the width and the height of the sound which gives you a very immersive sound especially running two of the speakers at the same time. The biggest thing to know is that these speakers have a very specific sweet spot. Sit in the right position, and they sound great. Move outside of it, and the sound can quickly become harsh and less enjoyable. That makes them feel a bit unforgiving depending on your setup. Where Denon really shines is the HEOS app. Controlling audio—whether it’s a single speaker, a stereo pair, or multiple rooms—is super intuitive. You can group speakers, move music around your home, and everything just works. Plus, with AirPlay 2, you can still control playback directly from your iPhone and even select multiple speakers at once. You can also connect your own high definition audio services directly through the app like Tidal, Deezer or Amazon Music and stream lossless or Dolby Atmos content. Overall, I’m in a bit of a mixed spot with these. The build quality is top-tier, and the HEOS ecosystem is genuinely impressive and easy to use. When the speakers are set up just right, they can sound really, really good. But the low-end performance doesn’t quite match competitors in this price range, and the narrow sweet spot means you have to put in some effort to get the best experience. If you’re willing to tweak placement and settings, you’ll likely be happy. If you want something that sounds great right out of the box with minimal effort, these might leave you a little frustrated.

As a long-time Sonos user with speakers scattered across pretty much every room, I went into the Denon Home 400 expecting “good, but not Sonos-good.” I was wrong. The Denon Home Ecosystem is a serious contender in multi room audio. Let’s start with the obvious: sound. The Denon Home 400 delivers rich, room-filling audio that immediately grabs your attention. We’re talking a six-driver setup with dedicated amps and upward-firing speakers, which means you’re not just hearing music…you’re sitting inside it. The bass is deep and snappy, mids are full and natural, and highs stay crisp even when you crank it. There’s real separation between instruments, which is something a lot of wireless speakers claim but don’t actually deliver. This one does. The Dolby Atmos capability isn’t just a gimmic…it actually adds dimension. You get height and width that makes the soundstage feel way bigger than the speaker itself. It’s not replacing a full home theater, but for a single unit, it’s seriously impressive. Setup and ecosystem integration are where the Denon Home system really shines. The HEOS platform makes adding speakers painless, and pairing this with other Denon gear..especially something like the Denon Home 200 or stepping up to another Home 400 as part of a multi-room setup, is seamless. You can group rooms, sync audio, and control everything without fighting the app. Its a very well thought out functional ecosystem. Design-wise, it’s clean and understated, nothing flashy, but it looks premium and fits anywhere. Controls are intuitive, and thankfully there are physical touch controls so you’re not 100% dependent on your phone. Now, let’s address the elephant in the room: Sonos. As I mentioned, I’ve been in that ecosystem for years, and it’s still the benchmark as far as Im concerned. But Denon is no longer playing catch up. The Home 400, especially, feels like a legit rival. The sound quality might actually be better than Sonos in some cases, especially if you care about richer, more detailed audio. Bottom line: if you’re already deep in Sonos, you’re probably not ripping everything out tomorrow. But if you’re building a system…or even just adding a serious speaker to your home setup, the Denon Home lineup, led by the 400, deserves a hard look. This isn’t a “budget alternative.” It’s a real contender and I didnt think I’d be saying that. Highly Reccomended!

It’s kinda refreshing to have a speaker that doesn’t make you fight with it for an hour before you can actually use it. Wait… is that still a thing? I might be showing my age here. For the most part, I think devices are fairly easy to setup and use fairly quick out of the box… with exceptions of course. Fortunately, the Denon HOME 400 was not the exception here. Setup was painless and quick. I’m a fan of the HEOS app since it walked me through everything and I had music playing pretty quick. I use Spotify Premium and didn’t have any issues, which was a relief because I have noticed some issues with older devices not connecting properly anymore. Denon does sound, bottom line. The HOME 400 shows why it’s expensive… for a good reason. The sound has a huge presence to it — deep lows that don’t get muddy, clear vocals, and enough detail in the highs that you notice little things in songs you normally miss on smaller speakers. In a world full of portable Bluetooth speakers and tinny phones, this is always nice. It fills a room effortlessly and creates that kind of listening experience where you stop what you’re doing just to enjoy the music for a while. I was a little worried about the HEOS app based on some stuff I read before getting the actual speaker. However, I didn’t experience any issues (seems like it may depend on how you stream your music but for me… excellent). It’s clean, easy to navigate, and worked flawlessly with Spotify. I was able to jump between playlists, control playback, and stream without issue. Denon got the balance here between premium sound, lots of features, and user-friendly design. The HOME 400 feels like a product built for people who want excellent audio without needing to be an audio engineer to set it up.

First off, the speaker sounds decent and does perform as a wireless smart speaker should. But is that enough...In my opinion, no. I expected more at this price point and from Denon. This is a pretty competitive speaker category, and nothing about it feels like it is trying to outperform the competition. The app is not super intuitive and trying to link two of these together was a headache finding the way to do so. The volume up/down increases and decreases too much for one click. When you want to listen at night, you either can't hear it or the whole house gets to listen. I will say it does feel well built, has a nice soft touch, but there is nothing to love about the design. The sound is room filling, but not enveloping. It's just there with no excitement to use it. I don't have other app enabled Denon products and maybe if you have other devices on the Heos system this would be a good add-on, but as a stand alone product, the sound quality doesn't make me want to add more Denon/Heos products.

I've used other smart wireless speakers before and this by far is the best experience from my experience at least. I have been using 2 speakers in this ecosystem this and the smaller 200 speaker as well. This brand is well known high end. You can connect these with Bluetooth as a secondary way but you primarily want to use this with WiFi so you can easily switch between speakers if you have multiple ones. You can use popular music services with the exception of Apple music although I have no idea if it's Denon's fault or Apple. But Apple doesn't work with other smart systems either so I have no clue. But you can use Spotify, tidal and some more as well. I've been using this with Spotify mostly although I have tried this with Apple music when connecting it to Bluetooth to try that out. With it connected by Bluetooth it works like any other Bluetooth speaker. It's fine. But when you're using this with the HEOS app you can use your desired app and connect it with whichever speaker you want all connected by WiFi. No need to manually switch connections. As far as sound quality this is amazing. It's high fidelity and quite loud
