amazon EarSonics SM2 iFI reviews
The SM2-iFI has an ear hook design, with housing made of transparent plastic, and EarSonic says it is very hard and very durable. I do not appreciate the creation of the SM2-iFi even found it very normal and nothing outstanding. But when used in continuous time, the SM2 gives you comfortable, lightweight, and especially good soundproofing, which you never really get in any headset. Other like RHA T20 or Dunu DN2000J …
While the earphones are the cheapest, EarSonic still equips the SM2-iFI with their best accessories such as removable cable, headset case, tip headset, etc. There is no difference compared to other high-end models. That is a great headset.
More about the signal cable, the cable used on the company’s highest-end model is the S-EM6; the cable is designed with an L connector and gold-plated, fairly conductive. The soft feel gives the user an insecure feeling of durability. Still, in practice, the weak and lightweight features make the user feel more comfortable and flexible, avoiding the wire rubbing against clothes.
Inside each ear, the SM2-iFI has two BA drivers, one of which is low and one high, with two separate channels. The sensitivity of the SM2-iFi is pretty high at 116dB / mW, but luckily the 44 ohms resistance is not too low. That makes the headset usable with more devices without the risk of breaking down. In addition to the 20 Hz -19 kHz frequency range, this is not a headset for treb enthusiasts, but good news for those who want to enjoy the altitude.
This review used two more popular headphones and are very popular recently for comparison: the RHA T20 and Dunu DN2000J. I use the device I use is ibasso DX80, Sony phone Z5, Apple iphone6S + C6, MacBook pro + DAC / amp ibasso D14, and Cayin C5 amp.
Comfort and sound insulation:
The housing of the SM2-iFI is the largest in the three ears, but in the slightest, the ear is quite large, so it wears quite firm and comfortable, but if you have small ears, you may a bit difficult when wearing SM2-iFI.
My favorite part of the SM2-iFI is the sound tube, EarSonic makes it very small, which makes the earphones pushed deeper into the ear, but you do not get the feeling of excitement and cramped; at this point, Dunu does poorly. Mostly, the RHA T20i is a bit better. The same way that he designed the sound like a small ant to the sound ability of the three ears also different, SM2-iFI is very good soundproof and better, if the soundproofing: SM2-iFI reached 9/10 points, RHA T20 is 7/10 and DN2000J is only 6/10.
Compatibility with the mobile phones: With all three handsets, the phone sounds good, but unlike the DN-2000J and T20, you only need to turn on the volume level of 40 to 50%. Obviously, with the SM2-iFI, you need to have a larger volume level, about 60%. And the same on the DX80.
Ability to improve the sound quality when using AMP: When combined with D14 or Cayin C5, the results showed that the sound of all three ears is significantly improved, especially with SM2-iFI change is. That is also rooted because the impedance of SM2 is quite high compared to the other two ears. With the SM2-iFI, space is wider, the mid is pushed back, the bass is deeper and more concentrated, and the treb also has more to show.
The SM2-iFI features a darker, more powerful bass with bass that is very close to the bass of the Dynamic Speaker, with a thick, warm mid-section that is quite smooth. That is the main sound sign of the company. This sound sign has made its brand firm.
Unlike the SM64 or the more advanced Earsonic earbuds, the SM2-iFI has many bass and midrange accents, making it unmatched by anyone. Especially, that use a lightweight headset like the RHA M750, or the Re-400, the DN-2000J will hear the SM2-iFI quite hard to hear, but if you have the patience to listen to it for a few days, And when you are accustomed to the quality of it, now you recognize the good, its subtle. But the detail of the SM2-iFI’s sound is still very good, especially in the bass and mid-range with a lot of charm.
That is probably the most valuable sound of SM2, Strong bass with no dynamic headphones, the first to wear SM2 that we hear is bass. The bass volume is above average, not too much to be annoying, but it’s more DN2000J and a bit or less than the T20 when wearing a filtered bass. Bass is made for both bass and sub-bass, without boom and not overdose so overwhelming, the bass of SM2 is quite easy to listen to and quite addictive.
Mid-bass is quite soft, punchy is also quite dark. The mid-bass and general bass of SM2 is quite the opposite of the DN2000J; at DN2000J, the bass is not much but bright and sharp, punchy strength. But SM2 is quite a lot of bass, heavy and strong but not sharp. The mid-bass of SM2 is quite fast; play and then pull the tail very little then off.
An extension is probably the sub-bass. Sub-bass down very deep, not rolled off a bit. With Walking in the air, the sub-bass was very clear, not missing a second. The sub-bass of SM2 is made very sound and thick, plus the dark background should sound very heavy. SM2 has a pretty bass volume, less roll-off but is played very lyrically. If you are not familiar with sub-bass, you will not like the bass of SM2 or vice versa. You will be very addicted to it for a while. This bass is suitable for slow ballads, special melodies for light jazz.
The middle part is probably the most worthy part of SM2. In combination with dark sources, SM2’s midrange is darker. I have the opportunity to try SM2 with Sony Xperia Z5. Both are products that sound very dark, so when combined with a very thick sound, the midpoint becomes dense and quite difficult to hear. SM2 shows its mid-range strengths only when combined with a strong and light-focused or at least neutral source; the ibasso DX80, iPhone 6S + C6 are good sources for SM2.
Even when combined with a light source like the iPhone + Cyain C6, the midrange of SM2 still has its characteristic darkening, albeit diminished considerably. But the strength of the mid SM2 is that the details are very good. Although dark, made very smooth, and croaking the words of the mouth, swallowing the singer’s saliva or musicians inadvertent touched, the strings are still shown. That is the point that makes SM2 different from the headphones at a lower price.
Mid is made extremely clear and hits a lot of mid basses. That is the bright spot and its special characteristics; it helps the space wider and deeper while also helping SM2 reproduce male and female bass. The high mid SM2 was not very high, was rolled off. In return, the ability to remove sibilance extremely well in the high mid-range and treble. Even the most sibilant voices like Yao Si Ting and Emi Fujita are never affected by this phenomenon. That is a very easy to hear and emotional mid and not easy to coordinate to get the best quality. I have tried SM2 with the DX80 ibasso and found the duo quite suitable, especially making the mid SM2 midrange a bit brighter, thinner, and well suited to more people!

Since I feel on the midrange and bass bands, SM2-iFI was not strong on the treble band. Treble SM2 has a modest amount, not much, and is not completely lost. However, the sound field of SM2 is quite good compared to a headset that is mostly mid-tone in the middle, so when the treble is played, it becomes very clear to recognize. Treble performs the task of making the background, not creating many points for the song. The SM2 is not a perfect headset for treble seekers in both volume and brightness and colors in the high band!
The SM2-iFI is currently EarSonics’s lowest-priced earphone, but its price has risen to $350. That shows that the company mainly makes headphones for the Audiophile High-end; SM2-iFI will be a first-hand product for beginners in the Audiophile. The SM2-iFI features a distinctive dark tone, extremely heavy bass, mid-dark but sweet, smooth and detail, soft treble. Although the cheapest product, SM2 is still a hearing aid worth hearing and worth long-term use. Suppose you are used to headphones Beats, Sony, Bose. You will feel that upgrading to the SM2-iFI is worthwhile.
