Latest reviews

Not quite there again from Aukey
Pros: Price, SQ considering the price, Ergonomics
Cons: Call Quality, Defaulting to SBC, Remaining connected in the case!
I paid for these headphones, as with every set I review, and receive nothing in return from the manufacturer.

How I review:

Sound Quality

What I measure here is the subjective and objective. I listen to a few key tracks, some FLAC, some bad quality mp3's, streaming services, audio books and tracks I know have been so badly produced they will probably clip the top or the bottom end. Usually I listen to one album in particular on FLAC, which I know very well, and also Bolero, which again I also know inside out.

I then test a few key variables such as FR and Spectral Flatness using an acoustic mic setup. Some others too, but I won't go into detail unless it's necessary.

I do this just for confirmation of what I'm hearing. I'm not Scarbir, I'm not The Sound Guys. I have a demanding day job, study, and have three kids, so no long essays in these reviews.

Microphone Quality

I conduct a few different tests, as follows:

Indoor, static, silence
Indoor, static, ambient noise 40-60 dB-A
Indoor, static, high frequency ambient noise
Indoor, static, low frequency ambient noise

All of the above but moving
All of the above moving away from the receiver

Outdoor, static, ambient noise 40-80db
Outdoor, moving, ambient noise 40-80db
Outdoor, under a nearby railway bridge where lorries pass through

All are recorded for 1-3 minutes for future comparisons. I look for voice clarity, voice clarity among noise and glitches.

INAIRS foam tips
ikko i-planet foam tips


As per the sound quality tests, I usually test the ANC at the same time, looking for low and high frequency performance as well as my pet peeve, vertigo and jawache (Not applicable here)


I use earbuds in four activities - calls, exercise, commute and relaxing. All three are taken into consideration to try to find the use case, as finding the perfect earbud is, lets face it, never going to happen.


I find most perform almost identically, but do the usual walk test, especially around congested 2,4ghz wifi areas. I leave a router on 40MHz just in case it messes with it, why the hell not?!

Ok, so onto the review:

Real Life Experience

The Unboxing - 7/10




Similar to their other models, this wasn't quite as impressive as the EP-N5. Aukey's advertising and marketing is generally understated and the box feels like an environmentally friendly brand. Whether it is or not is not for debate here - it's the angle they've gone with, and who am I to judge...all I care about is whether these sound good or not!

As per my previous Aukey reviews, the symbolic matrix style card is included again. I'm still none the wiser, but I like it.

Inside the box, the USB charging cable and tips are located in a section below the case. It features 3 sets of tips, which are different from most by deploying a red inside colour scheme.

There is a manual and a quick start guide but in all honesty you won't need it, these are very straightforward to set up.

The buds have blue stickers on the battery points - more on this later - but make sure you remove and charge before use.

The Case - 7/10







The case is nothing to write home about really, but it is nice and compact and well finished inside and out. It gives an extra 4 charges, taking the total charge up to 25 hours - below most earbuds, but acceptable.

The Ergonomics - 9/10




One thing Aukey never fail to get right is the fit. Once again these are ergonomically excellent. The stem lines along the jaw beautifully and like the branding, is understated. Once again, wearing Aukey earbuds is no hassle at all. The bulbous design is not uncomfortable, but provides decent passive noise isolation, although the finish on the mic holes is bad close up.


Despite being stem shaped, they are about the size of the Tronsmart Onyx Free - much shorter than the pictured Boltune BT-BH024, but have a nice, flat touch area to ensure good controls.

Sound Quality - 7/10 (for the price paid), 6/10 (raw score)

It is always a difficult balance reviewing raw sound quality against intermediate sound quality (i.e. sound quality against price).

Subjective tests were OK. I wasn't expecting much after the EP-N5. Actually, they aren't too bad, if a little unrefined. The mids are chaotic at times but for those that like house music these do OK.

With no aptx support these are meant to default to AAC on Windows 10 and iPhone. They don't. They default to SBC on Windows. Why I have no idea.

Annotation 2020-08-30 184109.jpg

Objective tests showed a drop of at 17KHz. These are the total opposite to the EP-N5 which are flat and unresponsive - these have some strange peaks - the spectral flatness is, well, lets just say all over the shop, but these are £18 earbuds - if you want refined sound, you ain't gonna get it at this price.

Call Quality - Indoors - 4/10, Outdoors - 2/10

Initially, these were the worst sounding earbuds I have ever tested. I thought the Nillkin TW004 were bad, these were so bad I actually thought they may be faulty. The volume waned in and out throughout various recordings and calls with my voice impossible to decode.

This seems strange as the mic arrays are well-placed, but these MEMS mic systems seem to be a disaster in every set I've tested.

After multiple resets, they ended up settling down, but they don't isolate anything - all background noise is picked up. And I've adjusted the score because there are some far worse as I've since discovered!

Connectivity, Controls and Other Features - 5.5/10

As well as getting the booby prize for calls, these also struggle with connectivity. Not much worse than the rest, but they cut off at around 7-8m, or at least start to struggle.

Controls are, well, better than some. Nice flat, finger sized area to touch that is responsive and intuitive. Double tapping answers calls (you don't wanna do that), triple tapping activates SIRI. You can play and pause, and skip tracks, but no volume.

But here's the killer. The earbuds remain connected to your device even when you put them back in the case. You have to manually find them and disconnect them. What?! the blue stickers that cover the battery connections - now I understand why!

Battery Life - 7/10

Battery Life is pretty good and 1 hour charge is great.

Final Comments

It's another average set of earbuds from Aukey. For £18 you can do a LOT worse than these. The problem areas: the microphones, the strange charging issue, the defaulting to SBC and the poor connectivity are, even at this price point, not really acceptable.

Unfortunately, I have to give Aukey another poor rating, which I hate doing because their earbuds always look so nice, but practicality has to take precedence - these just don't pass the test.

Price Weighted Score: 65%

Raw Score: 50%

Thank you for this review. The blue stickers on the contact point, should they stay or go? I had difficulty pairing the ear buds initially, but I wonder if thats more my lack of knowledge rather than the buds themselves as they did eventually show up. I tested the microphone (indoors no background noise) and it seemed clear enough for me, will test outside later on but just mention as you suggested whether yours were faulty. The 2 points I would consider negatives for me so far (its only been a day, but these are also only simple earbuds) are when they connect the volume on my device always goes straight to maximum which requires me to turn down each time, or jump if I'm wearing them at the same time; also an odd and possibly unique to me issue is that they hurt and sting a little inside my ear when I smile!
Yeah I've read a few complaining about the fit. Aukey just fit really nicely for me every time. No smiling issues!

I have reset them multiple times and they sorted themselves out, the mic became synchronised and it didn't sound terrible (but certainly not good) as soon as any kind of background noise was introduced.

They are very good for the money - you can do a lot worse in the sub £20 category.
