BYZ SE378 – Review

BYZ SE-378

BYZ SE378

| 10 mm Driver |



? The BYZ SE378 are a budget friendly earphone but belong to a brand that has some good acceptance among listeners, so despite their very low price they could offer a good value for money with its slightly bigger than average 10 mm dynamic driver. The housings of the BYZ SE378 are very small, in the size category of the JBL T110, UiiSii HM7 or sort of the Plextone X41M but substantially shorter than the Elephone E1 or the KZ EDR2. Materials used for the housings are lightweighted plastics and a metal disc on the rear part of the housings. Cable quality, design and feel is among the most pleasing we have felt so far, they have a very nicely transparent rubberized and slightly matte or pearled finish that looks high quality and provide a satisfying feel to the touch. There is an inline microphone and 1 button control on the cable but it is not placed as most earphones, they are positioned at the bifurcation section of the cable which makes it remain at chest height; we found that this provides an easier position to grab and use the button but the microphone sits at a distance too far from the mouth. The stereo plug is angled at 45 degree which some people really dig, we personally do not have a special preference between 45 angled or L shaped. The BYZ SE378 is sold in white, yellowish, pink or black.

Accessories & Packaging

Out of the box you get only a cable clip and strangely no extra pair of eartips were found inside our package. Everything is packed in a standard box.

B

Bass & Sub Bass

The BYZ SE378 10 mm dynamic driver is able to provide a good amount of bass with nice punch and depth that will be more than enough to cover the bass requirements of any type of music but consider that their bass strength could be too much if you dislike punchy bass; conservative bass is not their style but neither a basshead level. After an EQ, the BYZ SE378 noticeably enhanced their mid-bass and sub-bass but if pushed far they fall into boomy sounding bass. Under our extreme bass tests with a Fiio E12 amplifier set to high gain, bass boost on and applying a custom basshed EQ, the BYZ SE378 were able to handle a jaw dropping quantity of amplification power, reaching up to 70% of a Fiio E12 amplificator maximum power, part of this is because being an earphone with a higher impedance (32 Ohms) than many other they need to be fed up with a higher quantity of power to be driven. Despite the incredible amplification power taken they were unable to provide any type of basshead impact or rumble but they gained much more punch and depth.

M

Mids & Vocals

Mids are overall recessed with warm but somewhat laid back lower vocals and lower mids, mostly they can sound congested due to mid-bass bleeding and taking over the general sound presence. Higher mids are not forward and do not become harsh. With an equalizer lower recession is removed significantly but higher mids start to show some harshness.

H

Highs & Treble

The highs of the BYZ SE378 are very recessed resulting in lack of  brightness and detail. A very mild degree of piercing highs can be perceived on very high notes while sibilance is felt it is not too strong but as always depends on the sensitivity and tolerance of each listener Equalizing highs are able to obtain some brightness and detail is gained, also sibilance gets enhanced.

Sound Leak

The sound leakage levels of the BYZ SE378 are medium to low, noise can be perceived by nearby people but not strongly nor very clear if you do not crank up the volume too much.

SI

Sound Isolation

The BYZ SE378 are able to fairly reduce surrounding noises but they are not outstanding nor provide a total isolation. If you prefer a total isolating level you should take a look at the KZ ZS3, KZ ZST, KZ ZS2 or the bluetooth earphone QCY QY8 among others.

C

Comfort

With a very classic earphone style of housings shape, small size and light plastic materials, the BYZ SE378 provide great comfort and pain-free usage even on long listening sessions.

EQ

Response to Equalization

The BYZ SE378 response to equalization is acceptable. Bass gets noticeably punchier and deeper but bass bleeding becomes clearly stronger and too boomy; mids and vocals improve significantly regarding recession issues but also a bit of harshness is introduced; highs obtain much more brightness and some detail but become sibilant and still despite the added brightness they still sound dark.
