KEF X300A WIRELESS Gunmetal – and to my surprise they sound amazing, these remind me allot of the LS3/5A speakers

Just upgraded from b & w mm1s. At first i was really underwhelmed before realising that you need to change the speaker settings to 24 bit, 96,0000hz. I have to say i was then completely overwhelmed. These speakers simply blow you away with a lovely smooth bass and sparkling treble. They can be played pretty loud with no distortion. My videos and tunes now just sound divine, absolutely 100% recommendedhad to return these as for some inexplicable reason they stopped working. It would appear when the wireless takes priority it knocks out the usb connection and i could not get usb back. A real pain and people at kef realty have no clue how to help. You cannot easily get the speakers back to a factory state and you cannot turn off the wireless in the speaker.

Excellent sound with a few issues. The first thing you notice about these speakers is the size. Each speaker is 280mm tall x 180mm wide x 243mm deep in size (according to the kef website) and they each weigh 7. Marketing the speakers as being for smartphones, mp3 players or even pcs is ridiculous. I have mine on my pc desk and they look a bit silly, almost as tall as my 20 inch widescreen monitor. They are however immaculately finished, the cases made from brushed gunmetal grey aluminium, the front of the units dominated by the speaker cones and free from buttons and dials, only a tiny green led glowing on the front of the left speaker to indicate that the power is on. Each speaker requires power, and standard pc-type ‘kettle’ cables are provided, one per speaker. It does seem excessive that you need two mains sockets just for speakers, and i’ve had to move a few things around to accommodate them. Inside the box you also find two usb leads, one for connecting the speakers together, the other for linking the left speaker to your computer (everything connects via the left speaker), plus two foam bungs for adjusting the bass output, which is useful if like me you have the speakers situated close to a wall. The left speaker has a volume control on the rear, a power switch for the system, and a 3. 5mm jack socket for plugging in a phone or mp3 player, but the cable isn’t supplied, surprisingly. Connect the speakers to each other, plug them into the mains, and switch them on.

I was astonished by the articulation and clarity of hese small loudspeakers. Even though the bass in the specifications is limited as would be expected from such small boxes it seldom feels lacking unless playing organ music and similar. It is however absolutely essential to have the axis of the tweeter at ear level if listening in near field conditions. The dac converter inside is just magnificent, easily matching the best stand alone ones in the higher echelons and with studio master high resolution downloads these really come alive and give my main system a good run for its money. I can but only applaud the kef genius here, these are truly a bargain. Here are the specifications for the KEF X300A WIRELESS Gunmetal:

  • Enter your model number
    to make sure this fits.
  • High fidelity design
  • High definition sound
  • High simplicity
  • Hi-Fi your computer – now in wireless
  • Pure and simple – configured in minutes

After spending endless amounts of time and cash i have finally found these and i love them, the sound they produce is full of. Finally found the speakers i’ve been looking for. After spending endless amounts of time and cash i have finally found these and i love them, the sound they produce is full of detail and just the right amount of bass for my personal liking, they do not distort no matter how loud they go and they are plenty loud enough for most people. I personally have the non wireless versions as i didn’t really see the need for wireless if they are to be connected to my computer anyway?.Plus some previous reviewers have had issues with the wireless versions and no such problems for me. I purchased the kef eggs before these and although they are very detailed they weren’t for me, these on the other hand are perfectif i had to give a negative it would be there size (for desktop speakers they are big) but without the size they wouldn’t produce the sound so there has to be a trade off.

Great sounding set of speakers.

Rarely in life do you get wow moments but when i clicked play on spotify and these kefs jumped into life did i feel it. The sound quality is astonishing, and i mean astonishing, i would say the best music sound i have ever heard. It was crisp and danced in your ears and really was something rather special to the point i called my neighbour in to listen as well. They are very well made (as you would expect) and very heavy (around 20kg) and they look amazing, yes sure they are expensive but reassuringly so and just blow cheap speakers out of the room. Strongly recommended as the best set of speakers i have ever heard.

Have moved to listing to music from my computer and was tired of poor sound. These speaker are expensive but well worth the upgrade.

If you want a pair of these bad boys it would help if you were really serious about your hi-fi. Firstly, these are expensive. Secondly, they are also huge – well, for desktop speakers they are – so only think about these if you have a big desk or proper speaker stands. Having said that the build quality is outstanding and the finish is slick & stylish. Of course, none of this matters if the sound fails to live up to expectations, and these are fantastic.I’m not an audiophile but i don’t have to be to appreciate the almost completely distortion free sound and wonderfully balanced tonal spectrum.

Amazing set of studio monitors. First of all, let’s be sure about the your needs if you are considering these monitors. – produce sound / music- listen to almost highest quality music, exactly as the producers meant them to be heard like- want an active set of monitors (which means you don’t want to use them through an external sound card (well, not exactly, i’ll come to this point later on))- non-biased sound (some hi-fi speakers are biased towards specific genres)let’s start with connectivity:you will be able to connect your speaker to your devices using a 3. 5mm standard headphone jack. Or, you can use the usb cable to connect them to your pc/mac. These options are nice, if you consider other studio monitors; which will require an external sound card to connect to your phone/tablet/mp3 player etc. This means that these speakers are active. You can think about it as they have their own sound card built in them. And the better part is, each speaker has its own dedicated card, which requires two separate power cables in this case. This gives additional power to the speakers, since each channel (left & right) is processed on separate devices, without being affected by each other.

Great sounding set of speakers.

Worth every penny: music like you won’t have heard it before (except live). . I’m so blown over by these speakers that i don’t know where to start. I am accustomed to reasonably good sound (bose, sennheiser). These, even though they are supposed to be ‘computer speakers’, beat the bose wave system hands down. I have never had such clarity of sound, such balance, such dynamics except in live performances (). Even on old recordings (kathleen ferrier singing malher’s lieder) there is no background hum, incredibly purity, no blurring and perfect bass. They are powerful enough to fill a 40m2 room with no trouble and most importantly, no distortion. If you are a hi fi fan you’ll know how rare that is. It’s like rediscovering what music is. Whatever i play comes out way, way better than what i’m accustomed to.

And to my surprise they sound amazing, these remind me allot of the ls3/5a speakers. Just brought a pair of kef x300a speakers, and to my surprise they sound amazing, these remind me allot of the ls3/5a speakers, and if you know anything about hifi, that quit a complement. I have played around with the setting on the x300a, and here are my tips. Put them on some stands and give them some room to breathe and you will not be disappointed, also worth connecting over usb, which give the best sound, due to letting you adjust the hz settings. 0hz 16bit integer and cannot be changed, which still sounds good, but does lack a bit of base, over usb you can up the hz to 96000. 0hz and 24bit integer which is what the speaker where designed to use, on these settings they sound fantastic.

    I use these kefs with my 27”. I use these kefs with my 27” mac and therefore don’t look too big. They took just a few hours of use to run in and offer superb sound across the whole sound spectrum, including bass.

    Update: not really bad at all. As much as i enjoyed a number of kef products in the last 15 years or so, buying the x300a (not on amazon) without proper auditioning was a big mistake. I was impressed by the build quality and expected a matching performance. While the x300a are quite a decent set for hi-res casual jazz/acoustic music listening, they are a big disappointment as far as rock/symphonic tracks are concerned. What is even more disappointing, the movie performance is just plain bad. While excelling at fine detail and delivering the signature uni-q midrange performance, the set just sounds thin and underpowered, especially for a product that takes acres of real estate on your desktop and has a matching price tag. How come kef ditched the sub connection???and bluetooth???this could make a world of difference and turn a half-baked idea into a stunning piece of modern hi-fi. Having lived with the x300a for about two years – with multitude of connection issues (the app is utterly awful) and a return to service after the wireless connectivity died altogether, i simply cannot recommend this product. Moving over to naim muso was a massive improvement, both in terms of sound quality and overall user experience. ——————————————————————————————————————————————————–update: the above review was based on listening to hi-res tracks on a windows 10 system.

    Stylish, audiophile quality speakers at a very good price. *one thing to point out first before i start this review is that i’ve owned two sets of these speakers as the first one broke after a year. There were no warning signs at all, it simply just stopped working. However, amazon were extremely helpful and sent me a new set of speakers allowing me to return the broken pair in the box of the new speakers. They have been working perfectly since they were replaced and it seemed that mine was a one-off case. *i’ve been using these as speakers for my pc for nearly two years now and they are very stylish and sound absolutely amazing. Although these speakers may seem expensive to the regular consumer, the price to audio quality is astonishing. However, the limited options of connectivity will frustrate more advanced users. The design of these speakers is simple, sleek and bound to fit into any décor. As these are powered speakers, they are very heavy.

    These are brilliant computer speakers. These are brilliant computer speakers. They feel really well made, heavy but ok for desk either side of large widescreen monitor. Set up is really plug and play except you do need to go into control panel, click on sound, double click on the kef speaker bar (they are recognised automatically) and then in ‘advanced’ go to 24 bit, 96000 hz studio quality to set the usb channel to highest fidelity. I am so glad i bought these. The sound is astonishingly detailed. The music i like is classical, but other albums also excellent. They are absolutely quiet themselves. I am noticing detail not heard even on my large hifi speakers in another room. At higher volumes (enough to be loud at the end of my flat) they seem to be distortion free – an astonishing achievement.

      1. I went through audioengine a5+s and the kef eggs before i just decided to pay out for the x300as. I kind of wish i had just got these from the start. If you are looking to buy some new speakers,don’t require bone shaking bass and have the money,. They certainly sound leagues better than any of the other speakers i tried (and they both sounded great to me to start with). As expected, they have a similar clarity and brilliance as the eggs, with a much more rounded, punchier sound. Bass is solid, though doesn’t go quite as low as the a5+s. Overall the sound is balanced, complex, dynamic (and makes me smile). Negatives for the x300as are that there is no sub output, which might not be good enough for some and also the 2 supplied usb cables are both only a few metres long – i brought a 5m cable for the speaker connection for about £5, so not a big deal. Unless something goes bang i doubt i will ever need to buy desktop speakers again.

    Very good speakers, very clean and transparent but there is pretty much no deep bass at low listening levels in my room and seating position. Maybe its because im used to my full range high end system or harman kardon go play which leads the way when it comes to big bass from small woofers (harman kardon atlas woofers are outstanding) but apart from my bass gripe they do sound fantastic. Dont expect deep bass notes unless you really crank them up then they will sing at the rated frequency response. If you like anything that has deep bass at low listening volumes i would think twice. Im keeping them because i appreciate the clarity and balance which is what they excell at, they sound stellar, the clarity and detail would cost 10x the price to achieve in a full set up with good bass so i think they are a great value. These really do dissapear and create a great soundstagepeople on here have over exsaggerated quite a bit so i thought i would set the record straight.
