Shanling M3X review: Cute and powerful


I am impressed with Shanling. M5S was slightly cold and marginally less dynamic but they have improved a lot. Each brands its own flavours and they try to be more and more accurate in every aspect with each iteration and revision and that is true in this scenario. It’s an ever evolving area and the ES9219C does exactly the same, it improves in most aspects. Plenty of credit goes to Shanling for the tuning and algorithms too.

Over the M5S, M3X brings better clarity, accuracy and precision to the table. The dynamic range and sonicality are better too. It strikes a very good balance between being analytical and musical. I can lable the M3X colourless but it does have a bit of brightness with the treble instruments.


The M3X has very good bass response. The bass notes have very good texture. The excellent sub-bass extension coupled with nice body and details delivers a satisfying lower end. It is nicely voluminous with admirable accuracy. It has good amount of rumble and even the ER-4P manager to drop some pleasing bass notes. The sub-bass body and rumble are meaty and voluminous. It doesn’t restrict or stimulate the IEM for more grunt. The mid bass has a slightly voluminous body giving the lower end good amount of weight and fullness. The decay speed is snappy, it does not have the dryness and do not vanish into thin air like the Playmate. The M6 maintains natural amount of juice, closer to how is intended to be perceived. It perfectly fits someone who likes good amount of details, accuracy and precision over the heft and wooly thump. Another funny thing is, M3X simply do not let any IEM lose control, unlike the LG G7. The faster, more defined notes give the lower end very good resolution and clarity. If a more voluminous delivery is the need of the hour feel free to EQ, the response is very good. One can definitely pair with well balanced headphones like the Fischer audio M12s and enjoy the delicacies with a lot of accuracy and can be paired with something bassy to bring a bit more discipline and control.


Unlike the M6 the M3X has slightly less emphasized mid range, they gave it a bit of flavor after all. Thankfully the amount of details is intact and guess what, this mid range has a more engaging vocal region this time. The whole mid range has excellent details. It is not the harsh and humid type clarity but the calm and cool type of visibility. It slightly trades juiciness for a bit more cleanliness and dynamism. The delivery is effortless and the imaging is clean. The clarity and transparency along with natural decay speed leaves a very likable taste. Notes have slightly thinner body while finishing is without any perkiness or sharpness. The ability of details retrieval is very good. It perfectly balances the foreground and background transparency managing to bring out the micro details of the foreground without any problem. If your IEM is decent, you will not miss a single detail.

Vocals have very good clarity and definition with nice texture and details. It brings out livelier and jollier feel to the music. Let it be male or female vocals both have accurate depth and finish but favor female vocals a bit more. The upper mid range is well in line with the rest of spectrum but can feel a bit more attacking.


After coming from a livelier and vivid sounding mid range the M3X nicely maintains the eagerness. It has a very good sparkly and pace. It has a bit more attack and the finishing sharpness is very engaging. The directional cues are very good and as vivid as the M6. Notes have accurate sharpness with a slightly sparkly finishing and fun feel along with accurate body and excellent texture. The decay is on the faster side. Abundance of details is 2nd to none. The treble extension is excellent with plenty of room for cue placement. Instruments have excellent layering and separation with a lot of space and air.

The only down side of the M3X is its slightly more aggressive attack, it can put some off since it can make balanced and already bright sounding IEMs even more attacking, but if you love this attack, M3X is very enjoyable. This thing has both up and down sides. If you don’t have very bright sounding headgear this is not a thing bother about.


The stage of M3X feels very natural with expansion where the instruments have plenty of space and air between them. The instrumental density is excellent. There is no hollowness or unnecessary space in the stage. I have not experienced the ultra high end DAPs but even the likes of AK KANN doesn’t have a bigger stage than this. The distribution of space is admirably even, none of the parts of the spectrum takes unreasonable space letting the whole spectrum have their own freedom of expression and expansion. The stage is slightly taller while sacrificing a bit of depth and width but is fairly satisfying.

In general the stage size and the projection depend on the headgear. The IEM and headphone does play a huge part but the naturally expansive stage size of the M6 does add some extra dimension to the mix.


What is an excellent source which can’t play well with the headgears. The M6 with its excellent balance pairs very well with all type of earphones and headphones let it be single BA, multi BA or demanding ES hybrids.

With ER-4P (9/10) : (single ended)

What makes the ETY 4 micro series great is excellently exhibited by the M3X. Compared to more dry and emotionless DX160, M3X exhibits its artfulness and brings out good lower end body while maintaining the usual excellence with details. The slight brightness of the 4P is well preserved here. The pairing brings out the best out of the 4P if you enjoy the sparkle and attack. Not only it sounds more involving and resolving it leans a bit more into the analytical side. If your ER-4P needs a change of stance, M3X get more bite.

Shozy Pola39 (9.5/10) :-

The ES hybrid is a TOTL IEM with a well balanced signature and it pairs exceptionally well with the M3X. The bass is slightly tighter while having a hair better texture. The sub-bass have nice rumble and extension to it. Mid range is slightly less energetic, vocals have nice attack with plenty of texture. The instruments have excellent clarity and details. The stage size is taller but the Pola39’s natural expansion manages this effortlessly.

The Pola39 already have a tendency of being a very revealing IEM, it can expose any shortcoming of the recording or the source and the M3X helps with it. This pairing is nothing short of Excellent.

Shnaling ME700 Lite (9/10) :-

For me, this is one of the best IEM under $500 and the M3X pairing makes it even more appealing.

The slight lack of volume with the sub-bass rumble is a bit more present with the M3X than the Earmen Sparrow. It brings a bit more definition and texture to the mix too. The mid range is more or less the same but the M3X maintains excellent resolution and accuracy. The only point where the pairing feels a bit aggressive is the upper mid lower treble region. The slight bit of sharpness inherited by the ME700 Lite gets boosted by the M3X. It brings taller notes with some sharpness. Stage size is very good with this pairing.

DUNU EST112 (9/10) :-

EST 112 is an excellent IEM in its own but the only problem is the stage. But good thing is both have 4.4mm options and that improves the stage size by around 20-25%.

This pairing is impressive to say the least. The slight lack of attack from the EST112 is nicely brought up by the M3X. It brings a bit more sub-bass thump while the mid bass loses some body making it marginally more linear. The slight lack of mid forwardness is not really helped by the M3X sadly but it does not tamper with it delivering excellent transparency and clarity with a bit more texture and details. The treble region is slightly more alive than usual with a bit more cleanliness. Layering is improved too.


I will keep this short and simple.

If you are looking for a budget DAP this should be the first choice. The closest competition is the DX160 and it sounds dry and unemotional. If sound quality is not enough for you look at the battery life. At an average of above 16hrs of playback time this has some of the best battery life for an android based DAP till date. And the build quality is excellent too. It is not heavy, it doesn’t have any problems of ticking sound of internal parts or anything similar. This time around the wheel is working perfectly too.

If you needs a DAP for under $400, this should be the one to consider.

  1. Very nice detail review and picking up minute notes in low, vocal and treble . I am a cowon fan but cowon is not available now so planning to buy shanling m3x. Is this on par with cowon, as i think nothing can beat cowon in sound quality.

    1. M3X is not exactly in the League of Cowon Daps, if you want to buy a Plenue R in pristine condition, write back.
