Somic MH403 – Review

Somic MH403

Somic MH403

| 9.2 mm Driver |



Somic is a headphone and earphone manufacturer with many products on the market, they even have a 2nd brand named Senicc. Somic has good acceptance among budget buyers and usually produce nicely designed earphones with good specs and very well accessorized. The Somic MH403 housing is so small that seems to be a microdriver earphone but actually has a fairly sized 9.2mm dynamic driver (the size of the earphone is almost the same of the Sennheiser CX 200 and even smaller than the Remax RM-565i, UiiSii Hi-705, KZ HDS3). Although they seem to be made of metal they are entirely made of plastic with a good paint that resembles metal, they are very light and have a nice quality tangle free flat cord. Somic sells the MH403 model in red with red cable, coffee color with red cable and in silver with white cable.

A

Accessories & Packaging

The Somic MH403 comes nicely packed in a very big box (considering how small these earphones are) with 3 extra eartips and a rounded carrying case with the Somic name on it.

B

Bass & Sub Bass

The Somic MH403 lacks sub-bass depth and mid-bass punch but overall bass is enough to warm up the sound signature. Although it may be lacking strength and energy for some people, it does have enough bass for many less bass hungry genres or for people that do not enjoy bass heavy earphones. Equalizing does not add much more bass response and everything falls into muddiness. When custom equalizating them for extreme bass and connecting them to a Fiio E12 portable amplifier set to high gain and bass boost on, the Somic MH403 were able to tolerate 50% of Fiio’s maximum power but although they can handle up to 50% without breaking, when going over 40% bass starts to distort. The MH403 gains mid-bass punch and sub-bass depth with a very slight rumble; expect a performance below the Remax RM-565i but stronger than the UiiSii Hi-705 and Joyroom JR-E102.

M

Mids & Vocals

Mids are recessed though not as to sound too muffled. Middle and higher mids are never harsh nor fatiguing. Overall mids and vocals may feel lacking energy and being too laid back. An eq can be applied and mids/vocals will open up and gain more presence without becoming boxy.

H

Highs & Treble

The highs of the Somic MH403 are just mildly recessed but still detail and definition can be perceived. They can become slightly piercing with high peaks. The MH403 presents no signs of sibilance. An eq can make them much brighter without excessive enhancement of piercing highs.

Sound Leak

The sound that leaks out of the Somic is average, volume levels will get reduced but may be clearly perceived by nearby people. They may not be the perfect match for very quiet situations.

SI

Sound Isolation

The Somic MH403 are averagely capable of isolating from surrounding noises. They will not totally isolate you from what is happening nearby but if using mediumly high to high volumes their capability improves much more.

C

Comfort

An extraordinary light and small housing makes the Somic MH403 very comfortable to use. They fit tight and securely enough as to make you feel safe that they will not fall from your ears under normal use. The shallow housing allows the MH403 to sit flush with the ears making them pain-free and easy to wear in bed while resting your head sideways on a pillow.

EQ

Response to Equalization

The Somic respond diversely to sound frequencies. Highs respond very well to custom equalization, making them much brighter and detailed without becoming piercing or sibilant. Mids and vocals can be brought forward and will become clearer without starting to sound harsh or boxy. On the contrary, bass does not give an optimal response to custom equalization. Bass will not gain much energy or depth and will make everything fall into muddiness.
