SIMGOT EM6L Review – Another Harman But Good One

After the EW200, EA500, and EA2000, which have single dynamic drivers and metal shells, today we are reviewing the EM6L from SIMGOT which comes in a 3D-printed resin shell (+metal faceplates) and has 5 drivers per side.

Developed upon the legacy of its predecessor, the EM5, SIMGOT EM6L comes with a 1DD+4BA hybrid driver configuration. EM6L combines an 8mm custom-designed high-polymer diaphragm dual-cavity dynamic driver to handle the mid-to-low frequencies. Alongside, two sets of balanced armature drivers take charge of the mid-to-high and high frequencies.

The stock cable is soft and handles very good in hand. Also has good color matching with the IEMs.

The H-2019 Target Curve is universally acclaimed for its three-frequency balance, precise soundstage reproduction, and accurate imaging. The newly launched EM6L earphone has been designed to adhere to the H-2019 Target Curve, promising a three-frequency balance, a natural soundstage, and an expansive audio field.

Tuned to the H-2019 curve, SIMGOT EM6L reproduces audio with accurate soundstage positioning and imaging, which is suitable for both gaming and music playback. Dynamic low-frequency response ensures precise positioning, while spatial sound effects create an immersive experience.


The Simgot EM6L comes with glossy black resin shells paired with polished black aluminum faceplates adorned with subtle gold logos. This minimalist yet sophisticated design looks premium. To be honest I like this style more than all metal design.

Included with the EM6L is a high-quality silver-plated copper (SPC) cable. This cable not only feels premium but also offers minimal microphonics, and it’s equipped with metal components, including a convenient chin slider. I wish that the angled 2-pin connector housings were made of metal too instead of plastic.

I want to thank SIMGOT for providing me with the review sample of the EM6L.



The EM6L boasts a mild V-shaped sound signature following the Harman target curve, with a notable emphasis on the sub-bass. This tuning, while safe and inoffensive, stands out for its expansive soundstage that extends both wide and deep.


The Simgot EM6L IEM puts a distinct emphasis on sub-bass performance, providing a rich foundation. The sub-bass notes take center stage, giving kick drums a pronounced depth and resonance, resulting in a thicker sonic profile.

The mid-bass takes a back seat and is outweighed by the sub-bass, leaving it and the lower mids somewhat lacking in fullness. Importantly, this emphasis on the sub-bass doesn’t overshadow the clarity and articulation in the midrange and treble frequencies, although it imbues both with warmth.

There’s good speed to the bass. It’s deep and impactful, with sub-bass frequencies creating a rumble in the jaw. At the same time, the low end remains clean and well-controlled, never bloated or creeping into the higher frequencies. Acoustic instruments in this range feel smooth and natural, never carrying any artificial weight or color.

EM6L has QDC style 2-pin connectors. Why?


The midrange follows a relatively neutral tonality with a slightly recessed lower mids and a lower treble boost, ramping up the clarity. Vocals have nice density and a natural timbre. Instruments have good body and dimensionality. There is no harshness here.

The transition from upper bass to lower midrange is smooth. Despite the slightly recessed upper bass, this transition is one of the smoothest in  IEMs at this price range. The lower to middle midrange has a neutral amount of body and is neither tilted toward thick nor thin. As a result, while some male vocals may lack a bit of body and power, the SIMGOT EM6L provides good vocal clarity. For the upper midrange, the EM6L again shows some great control. It has a calm upper midrange.

The metal faceplates are finger print magnets because of the coating.


The treble has great extension and sparkle, with ample air and micro-detail retrieval. It follows an inverted V-shape with emphasis on the lower and mid-treble. Cymbal hits have realistic decay and crashes. Higher up, the upper treble is smoothly rolled off, avoiding any fatiguing peaks or sibilances. The SIMGOT EM6L strikes a nice balance between energy and smoothness.

The mid-treble still shows a good amount of sparkle, and this allows instruments such as piccolos and crash cymbals to be “correct”. The treble extension is quite good and is on par with the best performers in this price range. The SIMGOT EM6L extends way up to the upper treble and remains smooth and silky sounding.



The sound stage is one of the strongest parts of the SIMGOT EM6L without a doubt. Especially in terms of width. Separation-wise things are very good, you get excellent stereo imaging and positioning with very good sharpness and focus. The SIMGOT EM6L is good on details, and also very good in terms of overall resolution and transparency for the asking price. It also has great micro detail ability and realistic timbre.



SIMGOT EM6L vs EA500 FR Graph

EA500 might be the most known model of SIMGOT. Because it has been loved by many audiophiles. The reason for this was the unexpected sound performance of the unit and of course the price tag. Compared to the EA500 the bigger brother EM6L has a different tuning starting with the lows, and on the upper mids and the treble area. In short EM6L’s tuning is more on the safer side because of the Harman style curve. The two are completely different in sound. The ones who find EA500 lacking in bass will be happier with the EM6L. But they also get less extension on the highs, although a minor difference, affects the sound in general. I still prefer the EA500 sound.

vs Truthear NOVA

SIMGOT EM6L vs Truthear NOVA

The Truthear NOVA, which I reviewed recently, is the direct competitor for the EM6L because they both follow the Harman curve and they both have 1DD+4BA driver configuration. Mids and treble values are almost identical but the big difference in lows, both in the sub-bass and mid-bass areas, gives them both different flavors of sound. The SIMGOT EM6L has a better definition and texture on the lows, and also a better impact. The amount of bass affects the mid-region naturally. EM6L has a thicker, more natural note weight in the mids which I prefer over NOVA.



The SIMGOT EM6L is a clean-sounding, nicely balanced, and resolving IEM with a spacious presentation. It also has good dynamics, tonality, and resolution. Its bass has good pace and kick, its mids are dynamic and resolving, and its treble is smooth but defined. If you like this kind of tuning then you should consider giving it a try.
