Sunlux SU-028 – Review

Sunlux SU-028


| 16 mm Driver | Neodymium Magnet |

? The SUNLUX SU-028 belong to a never seen before brand but claim to offer jaw dropping specs at an ultra cheap price. A huge 16mm dynamic driver (a size that can be seen on premium earphones like the Sony MDR-EX7500/EX800ST) and a neodymium magnet. The housing of the Sunlux are made of a very cheap and flimsy plastic, the cables are scarce and fragile too. When getting them on your hands you realize that the diameter of the housings is way too small to fit inside a driver with a 16mm diameter. So, we are starting to doubt about Sunlux’s claimed technical specs.

Accessories & Packaging

The earphones are packed inside a sliding cardboard box with no single accessory or extra eartips provided.



Bass & Sub Bass

The Sunlux clearly showed no sub-bass and barely any mid-bass. An EQ made no difference to the lack of bass. After our extreme bass tests they took 62% of a Fiio E12’s maximum power, gained a minimum quantity of mid-bass but still no sub-bass at all and did not generate any punch, rumble or impact. Obviously, the declared 16mm driver and neodymium magnet are a shameless lie.

Mids & Vocals

Mids are tinny, boxy and lower mids are laid back at the same time. Higher mids are harsh and will cause fatigue very quickly. An EQ did no difference.



Highs & Treble

Highs are very piercing and at times sibilant too. Moreover, they have no detail or definition and lack brightness. After using an EQ a bit of brightness and detail is gained but they become much more piercing.



Sound Leak

The sound that leaks out of these earphones is extreme, whatever you are listening to will be heard loud and clear by everybody, even on very highly noisy environments.



Sound Isolation

The Sunlux will barely reduce the level of surrounding noises and only if very high volume is used.




Their comfort is average, they are not excellently comfortable but similar to many stock earphones such as the Samsung Galaxty Note 4 stock iem.



Response to Equalization

The Sunlux showed no response at all to equalization, just a bit of detail and definition was achieved after equalizing higher audio frequencies but they became very piercing too.

We highly discourage anyone from trying to apply our testings to your own earphones, the risk of damaging or permanently breaking your iems is absolutely probable to happen. With our standardized equalization and amplification tests we push the limits of the earphones to the extreme. If anyway you decide to do so, we cannot be held responsible of the damage done to your equipment. Do it at your own risk.
