Jayfi X1 Bluetooth Earphones Review

Are the Jayfi X1 just another set of Bluetooth earphones are is there more to them than meets the eye?

In the box

Its already a good start for the X1 as they come with a wide variety of accessories, these include a carry pouch, its very nice and features some drawstrings to pull it tight. Its soft and won’t provide much impact protection, but its a welcome addition. You also get a Micro USB charging cable, some small, two medium and large set of eartips. You also get three ear wings (clear, Green and Black) all of these are different in terms of flexibility. The clear are the most flexible, the Green sit in the middle and the Black are the most rigid. Finally is the manuals and documents.


Design and Build

The design is well classy but nothing really too unique. That may be a good or bad thing depending on what you like. If you want something a bit special, then they might be a bit plain for your taste, but I quite like the more subdued styling.


The housing is made from a combination of Aluminium and plastic, it’s finished in a nice Black, which has a little bit of a subtle sparkle to it. Don’t worry as its not in your face, its actually very understated. There is also a noticeable cutout which is where you’d locate the wing. The front of the housing is plastic and finished in a Glossy Black, its here where you find the nozzle.


Round the back is a circular brushed pattern that looks again very nice and ties the whole classy look together. Its again solid as its made form Aviation grade Aluminium. This section also hides a little trick and that is in the form of a magnet. This allows them to close together and its great for when your not using them as you can more securely fit them around your neck.


Onto the cable now and its a pretty standard affair, its again Black so it doesn’t stand out from the rest of the design. Its pretty thick too and coated with TPE, meaning it shouldn’t really cause any problems over the short or even long term. Plus there is plenty of strain relief too. It measures a total of 700mm, which is plenty enough to fit from ear to ear and still give plenty of slack to rest on the back of your neck.


The remote is the next thing you’ll find, its made from plastic and coated with a smooth texture. It feels decently solid too. Of course not as solid as a metal one would, but it should last the life of the earphones.

On the remote you’ll find three buttons, these are again plastic but feel good. The buttons act as volume control, but they also double as skip track buttons too. The middle button is your main MFB and acts as play/pause, pairing, on/off as well as having the ability to reject and answer calls. You’ll also notice the LED notification above the plus button, this of course lets you know what’s going on, but more on that later.


The final thing you’ll see on here is the USB port for charging. It has a small rubber cover which keeps it protected. The cover is a bit fiddly and to be honest a bit of a pain to close fully. If you don’t then the earphones lose their ability to be sweatproof.


As a whole they’re nicely designed and well built for the price, my only gripe is the annoying USB cover. Yes its important but that still doesn’t mean that its not an irritation.


Comfort is usually a sore spot for me when it comes to earphones, but these are actually good. The angled nozzles help them sit better in my ear. Usually after one or two hours, I’m done, but with these I managed three plus before needing a break. Plus they’re very light too coming in at just 15g, meaning no tug.


The tips are pretty great too, I usually have either medium or small depending on the style of the tip and with these the small fit best. The tips though are soft, smooth and only started to cause fatigue after around three hours of use.


Its the same for the wings too. I tried all three and found the Black ones to be the best for me, they weren’t the most comfortable as they would be the clear ones. But the Black ones just seem to hold in better. But if you are using them for say sports and casual, you could always swap between your two preferred.


For exercise they are great, they don’t slip out of my ears and with the Black wings they stay firmly in my ears. Of course you can pick whichever works best for you, but those were my choice.


The JayFi use Bluetooth 4.1, which is fairly new and is backwards compatible, so if you have an older device you should be covered.

Connecting these to a device is very simple. You long press the middle button on the remote until the LED light flashes Red and Blue alternatively. Once that happens, simply activate Bluetooth and search. After a few seconds the Jayfi should appear, you’ll want to keep an eye out for JayFi X1 as that is the code. Once thats popped up, simply select it and let the devices do the rest.


In use

Using the X1 daily was a breeze, inserting them into your ear was easy and could be done one handed. It did take some practice, but after a few days it was easy enough to do. The remote is super simple and very accessible. It sits just above your shoulder and the buttons are very easy to press with your right hand. This is because they are well spaced apart and don’t require much force to activate them. I did have a few mis-presses where I hit the pause button instead of the volume controls. But again after some use you’ll quickly get used to them.

Swapping out the wings is easy too. You simply stretch them a little and pull them towards the nozzle. To put them back on, you again give them a little stretch and locate it in the groove.


Charging them was a bit of a pain thanks to the awkward USB cover. Its a bit fiddly to remove and sometimes if you don’t move it fully the USB connector won’t fit in. So its more of a chore than it should be.



This was a big let down. They were supposed to last up to 7 hours. I managed a measly 2 hours and 45 minutes at 65% volume. This is nowhere even close to the suggested time and to be honest, one of the worst performances I’ve ever encountered. Even the fully wireless SoundPeats Q29 managed to outlast them. I’m not sure why they didn’t last long as they have two decently sized 55Mah batteries in them. I have a feeling that one of the two batteries has either broken or come loose as this is way under half of what is achievable. If you look at the charge time below, this sort of confirms my theory as it only seems to be charging one battery.

Charge time is quoted at 1.5 hours, whereas mine only took 45 minutes. This again could be to do with the problem I mentioned above.

So maybe the poor battery performance is a just a defect?

Noise isolation and Leak

Isolation of these earphones is pretty great, they do manage to block out a fair amount of noise. The seal they create is pretty tight so therefore not much is going to get in. Of course how loud you have your music plays a big part, but even without music they do a decent job. I tested them on public transport and they did really well at blocking out most external noises. Of course they won’t be on a par with noise cancelling, but they are good in their own right.

Leak is well handled too, its pretty minimal and if you get the right tips then you aren’t going to really bother anyone. Of course if you do turn them up then leak does become a little more prominent, but these actually leak less than some other rivals I’ve tested.


When companies use technical jargon and new types of tech its hard to tell what to expect. These use something called SOUNDR jyi which is supposed to give the different frequencies better separation. They also use JHQ which is a form of supposedly lossless sound quality. To be honest I’ve had experience with lossless before and it was quite magical, but are these?

Well the sound is pretty average to be fair. Its just about what you’d expect from a pair at the price. They jargon they are using to sell these is to be honest not doing a deal.

The bass is decent, it packs a solid punch and the drop is fairly deep. The bass is fairly clear but can get a touch murky at times. Detail is average but on the plus side, it doesn’t hamper the rest of the frequencies.

The mids are just as good as any other pair at this price and with that you get decent levels of detail. But nowhere near what you’d expect to get from lossless. In sound separation is decent and you can identify what is happening, most of the time. If there is a lot going on, it becomes a little to much for these to handle. But for your average chart song they cope well. The colouration is quite neutral and they are not to warm nor too cool. Soundstage is lacking, but that is more a trait of earphones and st this price I wasn’t expecting it to be great.

Vocals are good, they are clean, clear but do lack a little potency. Detail is admirable and tonal quality is nice.

As a whole I was expecting better, when the advertise lossless sound that is what you’d expect, but these fail to deliver. If they didn’t advertise this as a feature then things maybe different. But when you advertise something, you need to deliver and these do not. If you take the marketing out the equation they are a decent sounding pair of earphones, but to be honest I’ve heard quite a few that sound just as good at the same price. So there is nothing in the sound department that sets them apart.


For £26.99 these are a serious mixed bag. On the one hand they are nicely designed, well constructed, comfortable, block out decent levels of noise and don’t leak too much. They also come with a lot of accessories which is an added bonus. On the other hand, the battery life was not great at all and the sound left a lot to be desired. Yes it was okay, but nothing that really sets them apart.

So should you get some. Its tough, yes the positives do just about outweigh the negatives but for me the poor battery life and sound let them down. Yes, I mentioned the battery could be a possible fault, but I can only review what I’ve got, so take that into account as well. But even so, the amount of competition out there, its still hard to say “go out and buy them”.

Score 6.5/10
