    Media 4 Soundbar

    Introducing our M4, a high-performance active speaker with a built-in subwoofer and Bluetooth, designed to deliver high fidelity music and high-quality audio from a TV, set top box, tablet and smartphone. This "What Hi-Fi" multiple award-winning hi-fi soundbar plays both music and movies with equal accomplishment, meaning you’ll get high-quality sound no matter what. Real bass is created by its acoustically matched, built-in, high-performance subwoofer. Enjoy a genuine cinematic experience with the M4.

    Built-In Subwoofer

    With both analogue and optical inputs, the unit is a complete one-box, standalone hi-fi system in its own right. It can be used with a variety of other entertainment sources, including streaming services like Spotify, CD players, portable music players, computers and internet radio. Its built-in subwoofer means no extra cables or separate subwoofer boxes are required.


    The M4 uses BMR loudspeaker drive units to deliver outstanding sonic performance and disperse the sound across an exceptionally wide area. So no matter where you sit in a room, you’ll still enjoy the full hi-fi or home cinema experience. We provide true audio with no added effects or digital signal processing to degrade the sound.

    Easy to Use

    The M4 couldn’t be easier to use: simply plug it in, connect to the source and it’s ready to go! It comes with a small, five-button IR remote control, but the M4 can also be operated by the remotes that come with Sky and Virgin set top boxes.

    This means fewer remotes to worry about, while still being in complete control. We’ve also taken care of worrying about turning the M4 off when not in use. After 20 minutes of inactivity, it automatically goes into standby mode.

    TVs, Movies & Music 

    The M4 is great for enhancing your normal TV sound, enjoying great music and immersing yourself into whatever movie you’re watching. It’s also a music lover’s best friend as it can connect to your CD player or stream wirelessly with Bluetooth. It brings a new level of enjoyment that you’ll wonder how you ever lived without it!

    M4 for Gaming

    Whether you play online, in your living room with a friend or simply on your own, you’ll almost feel like you’re in the game! Our M4 can connect to the Xbox One, Playstation 4 and other similar consoles to deliver an incredible gaming experience.

    Connecting the Soundbar

    The M4’s digital optical and analogue inputs mean it can connect to almost any entertainment source, from TVs and Sky or Virgin boxes to CD, DVD and Blu-Ray players and smartphones, tablets, portable music players, internet radios and computers.

    Pairing to Multiple Bluetooth Devices

    The M4 is Bluetooth compatible using aptX lossless Bluetooth for audio streaming, which means the wireless connection can sync to almost any Bluetooth-compatible audio device. The M4 can remember up to eight pairings, so when friends or family come over, a guest music player can connect in seconds. Our aptX Bluetooth is V4.0, but is compatible with older devices and will work with most V3.0, V2.0 and even V1.2 devices.

    Once connected to a specific device, the M4 will automatically stop searching for other devices. To connect to another device, disconnect the currently connected device.

    Please note: If you pair with a ninth device, the first paired device will be lost.

     NFC Connectivity

    Near Field Communication (NFC) allows you to link any NFC-enabled device to the M4 by simply touching your device to the ‘pairing’ point of top of the soundbar. Once connected, you can stream music wirelessly via Bluetooth.

    Soundbar Placement

    With its versatile design, the M4 can go nearly anywhere. Most people place it on their TV stand, mount it on the wall or place it on a piece of furniture like a bookshelf or table. All are great options as its slim depth allows for it to fit in tighter spaces while wall mounting it gets rid of clutter.

    Highly recommend Soundbar Review by Chong
    Good sound quality perform on the movie. Especially the vocal and surround sound are clear and sharp. You wouldn't feel the sound are noisy even grating. No others soundbar may perform like M4 do.

    While performing music/songs not very ideal. Not recommended for listening to music. Built-in subwoofer not much powerful if buyer would like to have strong woofer sound definitely purchase in bundle external woofer which will be perfect.

    Bluetooth and remote control range are limited, Not ideal for living hall space more than 400 sq ft above. If you have a small living hall or TV ROOM M4 is prefer choice.

    Overall best around bar even I had compare to previous brand / model I had with this budget. (Posted on 9/6/2018)
    Amazing Sound Quality, Amazing Value. HIGHLY RecommendedReview by Ben H
    I was looking for a high quality soundbar as a dual purpose unit for both HiFi music listening and home theater. This came highly reviewed, and I was not disappointed at all. In fact, I have been amazed and blown away by the soundbar.

    Build quality is simple and sturdy. Wall mounting plate is perfect; I mounted the bar right underneath my wall-mounted home theater screen in my living room. It sits neatly under the screen and takes up very little space.

    Connectivity-- I use an AptX bluetooth transmitter to send analog output from my turntable/amp on the other side of the room- near lossless audio quality and it sounds FAR better than the floor standing speakers I had used previously. You could get perfect audio quality if you connect your amplifier directly to the soundbar, but I can't for space reasons. The AptX bluetooth connection is perfect- I can also cast music to it from my computer, iPhone, basically anything.

    Theater-- Amazing bass for action movies and crystal clear dialogue. This unit easily fills our living room with sound and makes for an immersive theatrical experience.

    Sound quality-- The dynamic range on this unit is amazing. It retains high complexity even at low volumes. At high volumes I can hear every range of the frequency spectrum very clearly. I was amazed at how powerful the built-in subwoofer is. The low end projection of bass guitar, bass drum, and toms in my favorite records is just incredible. For my room, I would absolutely not need to add a subwoofer with this unit. Mid-range is extremely punchy and tight. The high end also shines through clearly without being too aggressive or tinny.

    I really do love this soundbar. I will add a few small complaints just so you believe that I'm a real consumer. The remote as fairly small, cheap, and flimsy. It performs the necessary functions, but adjusting volume is one place where the design could be improved. There is no graphical, visual, or any indicator that tells you how high/low the volume output of the unit is, so when you switch from sources with drastically different input levels you will have to do a bit of manual adjustment each time. There is no way to save volume settings for different channels. One other design flaw here is that the "bluetooth pairing" button is on the back of the unit. I think it would have been pretty easy to add a similar button to the remote so I could switch between devices without having to access the back of the unit each time.

    Again, small complaints on a product that I am EXTREMELY pleased with. The price is extremely reasonable for such value. Q Acoustics now has my attention for other audio products I might need in the future. (Posted on 3/25/2017)
    good sound but a few issuesReview by svald
    The soundbar was shipped and arrived quickly. The sound is great. Things that I don't like are: We can't sync the audio with the tv visual. The remote control has a very narrow range so if sitting even slightly to the side will not work. (Posted on 3/19/2017)
    Stealth Bomber BruteReview by psyclops
    Sonos Playbar sat in my online cart (bought, paid for, subsequently canceled) after impressive in-store demo. Purchase got derailed upon chance discovery of the M4 reviews. The more I read up on the Sonos, the less I wanted any part of it. Really didn't wish to be bothered with a time-consuming, ambient setup + the extra, added headache of dealing with yet another godawful remote-app. The M4 sounded like the Anti-Sonos. The recurrent, murky dialogue problem from movies & broadcasts has so far eluded me with every iteration of sound bar or surround-sound setup I could compile (within a reasonable budget); a futile, disappointing waste of money & effort. The M4 pro reviews were so across-the-board consistent in their enthusiasm, I determined to take a risk without benefit of even hearing the device and aggressively pressed the buy button. Simply put, the best audio decision ever made. Right out of the gate, the M4 delivered in a big way with an effortless, heavy lift of a typical BBC/PBS 'Sherlock' episode with all Cumberbatch mumblings & voiceovers gloriously up front with sound effects & music properly nuanced and balanced exactly as they should be. Dismiss the unnoticeable caveats regarding the remote's volume increments & lack of Dolby, DTS, etc (though an an added HDMI input does make my head spin). This is Sound the way it should sound: immersive indeed. The "old school" design could conceivably be off-putting to fashion-followers out there with its Brutalist look which really does bring to mind the original Stealth Bomber, but no doubt like its doppelganger, built to last.

    This thing rocks!Review by Kyle
    Everything about this speaker is a class act - from the packaging, to the product, to the sound it produces.

    I bought this unit to replace a Samsung sound bar that died about a year after I purchased it from Costco. I had read some good things about the Q Acoustics products but didn't know what to expect. After a week or use, I couldn't be happier.

    Even before hearing the sound, the quality of this product is apparent. It's a much more substantial speaker than the Samsung it replaced. The sound quality can't even really be compared. It's that much better.

    The speaker comes with both an analog and digital cables, a remote and a mounting bracket if you want to wall mount it, or 3 solid rubber dampeners if you're going to place it on a console of some sort.

    I was easily able to pair my iPhone using Blue Tooth to play music straight from my phone in addition of the digital optical cable connection with my TV.

    Highly recommended.

    Best Soundbar - PeriodReview by Plates1
    This is by far the best sound bar on the market. I've had a UK version of the product for several months and can't believe the audio quality. It fills a room regardless of where you put the device. You can be completely off axis from the device and hear virtually all the frequencies. This means that you don't need to sit in the "sweet spot" to get great audio - music or video. Enjoy!

    BTW, I'm buying these as gifts as a wedding present for my son and a graduation gift for my other son. (Posted on 7/18/2016)
