MEMT X7 review

Our Score
INTRODUCTION

MEMT, otherwise known as the Department of sound electro-acoustic Technology (Shenzhen) Co., Ltd. MEMT was founded in 2014 but until recently was unknown to most on Head-Fi until people got wind of their X5 IEM Today I’ll be looking at another IEM from their X series, the MEMT X7.

The X7 has an MSRP of $25 and is currently not yet available for purchase from the manufacturers Taobao store.  It should soon be available in various online stores.

This sample was sent to me for the purpose of an honest review. All opinions and observations here are my own based on my experience with the product. I have no affiliation with the company.

Cable length1.20 m
Sensitivity100+/-3dB

PACKAGING AND ACCESSORIES


The X7 is presented in MEMT’s familiar sky blue packaging. It has a fresh, clean look with the model number in large print on the front and a transparent window at the bottom giving a clear view of the earphones inside. Opening the magnetically sealed cover reveals a plastic cover over the earphones and accessory box. Both are held firmly in a smooth black foam material. It’s a fairly basic package but is of a fairly high quality when considering the low price.

The included accessories are:

  • 3 sets of silicon ear-tips (S, M, L)
  • 3 removeable/interchangeable silicone cable cinch in black or white
  • Velcro cable tie

And that about sums it up. There’s basically everything you need and the only extra thing I could want is a carrying case but of course the omission is understandable again when we consider the low cost.

BUILD, COMFORT AND ISOLATION


The X7 has a concave barrel shaped housing in rose gold color with silver nozzles and a silver disc on the rear separated from the main body by a thin black line. Personally I think that these look really attractive and was frankly surprised at the pleasing design when I first opened the box. What seems to be a standard feature of the MEMT X series and something that I love is the magnets in the rear housing that hold the two sides together. This is not only great for being able to wear them around your neck when not in use but also (and perhaps even more appealing) it really helps prevent the cable from ending up in a tangled mess. Brilliant!

The finish on the housings is really nice and smooth and something you might expect from a more expensive item. Nozzles on the X7 have a little raised section at the front end to keep tips in place but they’re slightly narrower than average so it can be difficult finding third party tips that stay firmly in place. Fortunately the supplied large tips are of good quality and (at least for me) fit my ears really well.

Onto the cable which is rather stiff and prone to microphonics but feels very strong and durable. There are good strain reliefs on the housings and plug but not so much on the inline control and Y-split but I don’t think it’s any cause for concern because as stated the cable is tough! The inline controller has 3 buttons so is a step up from the one on the X5 and it’s made from the same rose gold colored metal as the housings. There’s also a microphone built in so you can make calls if using with your smartphone. The Y-splitter is metal again and has X7 printed on one side. The cable terminates in a 45 degree, gold plated 3.5 mm plug.

So how do they feel in your ears? Well of course as with most traditional barrel shaped IEMs they’re good but because of the really smooth finish, slightly rounded back edges and quality ear-tips I’d say these are very comfortable indeed. I can wear them for hours on end with no problems whatsoever.

Isolation is slightly above average but as always this will be partly determined by how good a seal you’re getting with whichever tips you’re using. These are good for noisy environments and use in transit and will block out a good deal of outside noise.

Amping

As with most low impedance IEMs amplification isn’t necessary but I did find that with a higher powered source (ie: Matrix HPA-2C) the bass sounded less boomy and more controlled. I found the X7 to be fairly source dependent and found a brighter source gave the best results.

Summary

The general sound signature of the X7 is dark and warm with lots of BASS! Big bass, thick mids and subdued treble. Probably best suited for electronic and bass driven music or for watching action movies and playing games. These don’t hold back when it comes to bass. It’s like being next to a speaker tower on the dance floor at a rave. They’re not trying to be analytical or accurate but instead aim to cave in your skull and they have exactly that kind of impact.

Bass

Right, so by this stage you’ve probably guessed that these are a bassy IEM. Well that would be an understatement. These go beyond that and into the realm of the true basshead niche. Think ROCK Zircon levels with deep, rumbling sub-bass but unlike the Zircon the X7 also digs deeper into the mid-bass segment. It’s not the most textured or etched but it is by no means boomy and is contained well within the shells and you can feed them lots of power without fear of distortion. Got sinus problems? These might be able to fix that, just like eating a bowl of spicy Thai Tom Yum soup they will make your eyes water and nose run. While playing “Landing Party” by Solar Fields that is just how I felt. It’s too much for me personally but you can hardly be mad when “HEAVY BASS” is written in bold on the front of the box. I guess you could say “It does what it says on the box”. And then some.

Mids

The weighted warmth of the low end carries over into the lower midrange as well which means you may lose some details and it can sound a bit thick and veiled. Things still sound natural and fairly clear and are not overly congested. For the most part the mids hold their own really well against the bass and vocals are quite forward in the mix. Listening to “Ambitions” from Katatonia’s Dead End Kings the vocals are front and center and perfectly legible despite the thumping kick drums.

Treble

Treble is a little subdued resulting in a L-shaped signature with all the emphasis on the bass and lower midrange. However the timbre of the treble notes is actually really nice but just moderately recessed. So as long as you are not in the least bit bass-shy you should find these a non-fatiguing IEM. Cymbals and hi-hats sound very natural but are well in the background. Treble extension is quite good too, it’s just the level of the notes that is restrained.

Soundstage is average, being not dramatically wide but with some good depth, unusual for an IEM with such a warm signature.

Comparisons

VS MEMT X5 ($18 USD)

These are both very comfortable  to wear but the X5 comes out slightly ahead with it’s shorter body which makes the fit a bit more secure. The nozzles on the X7 are a bit longer and make it easier for securing different ear-tips. They also share the same cable which suffers from microphonics but is very robust. Although the X5 is a bassy IEM the X7 takes it to the extreme and suffers from bleeding into the midrange which is one of the X5’s strong points.

VS VJJB K4 ($17 USD)

The K4 is another bassy IEM but unlike the X7 it suffers much less from bass bleed and has less coloration in the midrange. The K4 also has a brighter, more energetic treble presentation. Build wise they’re both good but the aesthetics of the K4’s wooden housing has a certain appeal for this reviewer. The K4 is V-shaped with more treble where the X7 is L-shaped with more emphasis on the low frequencies and lower mids.

VS Tennmak Piano ($26 USD)

The Piano has a fast, punchy mid-bass and deep, well-extended sub-bass. In the midrange the Piano comes across as a little thin, a stark contrast to the thickness present with the X7. The Piano is more V-shaped with a brighter sound and more prominent treble. While the X7 is constructed from metal the Piano’s housings are plastic and worn over the ears. Tennmak’s offering also has detachable cables which provides more longevity.

CONCLUSION


The MEMT X7 is an IEM that falls into the true basshead category. It goes beyond a merely boosted bass to a genuinely massive one. I found the X7 responds really well to EQ and with some of the bass pulled out the details are starkly revealed, suggesting that the dynamic drivers are very capable and the thickness in the presentation is simply due to tuning. Even though this IEM doesn’t fall into my personal preferred sound signature I can’t help but admire it for what it is able to do. For the asking price the build quality of the housings is very good though it suffers from the same stiff, microphonic cable found on the X5. The included ear-tips are of good quality and I love the included silicone cable cinches. If you’re looking for a budget entry basshead IEM the MEMT X7 is worth taking a look at.
