QKZ X3 – Review

QKZ X3


QKZ X3

| 10 mm Dynamic Driver |





🎧 The QKZ X3 review is up and ready. QKZ is a brand that sells ultra budget-friendly earphones with, usually, solid construction and exceptional bang for buck relation.

The QKZ X3 features a single dynamic driver configuration with a diameter of 10 mm and (supposedly) titanium diaphragms. Every piece of the QKZ X3 is constructed in metal (housings and cable bifurcation), the earpieces have a bullet-style design and a black and silver color. On the side of the housings you will see the “Q” logo of QKZ and on the back part you will find a grill design that could suggest an open-back design.

This QKZ model has round cables that are very rubberized and have the same color pattern and finish that usually KZ uses in earphones such as the: KZ ATE, KZ EDR2, KZ ZSR, KZ ZST (and KZ ZST Pro), KZ ES3, KZ ED4, KZ ED7 and KZ ATEs.

If you buy the version with the inline mic you will get a 1-button remote/mic that will allow you to play/pause songs and answer/reject calls. The 3.5mm stereo mini plug has a 45 degree angle, something that many users appreciate.

We find important to denote that QKZ and KZ are two different brands despite their very similar name, we have mentioned it several times through out our previous QKZ Earphones Reviews but we think that it is always fundamental to clear up this fact that could lead to confusing both brands.

The QKZ X3 price will be lower for the QKZ X3 mic-less version, the mic/remote is compatible with Android and Apple devices.

You can buy the QKZ X3 in one color option, black.

Accessories & Packaging

The QKZ X3 unboxing results in 3 pair of eartips, a cable clip (sometimes not included) and an useful hard plastic carrying/storage case that looks almost identical to the one of the JVC HA-FX1X.

B

Bass & Sub Bass

The QKZ X3 bass is very fun with punchy mid-bass and very deep sub-bass. Their lower frequencies response is energetic and will cover all bass-intensive genres without a single problem. Despite their powerful bass, their sound is not excessively muddy nor dark.

Applying an EQ, their bass gets noticeably enhanced with a strong sub-bass depth increment.

During our extreme bass tests the QKZ X3 were able to handle 52% of the maximum power of a Fiio E12 amplifier while being set to high gain and with bass boost turned on; a custom basshead EQ was used. This extreme amplification and equalization made the QKZ X3 achieve such a massive increment of mid-bass punch and sub-bass depth that they were able to reach a basshead level of impact and rumble above the KZ ATE, Xiaomi Mi Pro HD but yet not as strong as the Xiaomi Mi In-Ear Headphones Pro, Pioneer SE-CX9, Pioneer SE-CX8 or the Sony MDR-EX650 and Sony MDR-EX800ST. While not being able to enter the Top Basshead Chart, their rumble is still not far from them.

M

Mids & Vocals

The QKZ X3 mids are warm and exhibit some mid-bass bleed that extends over some part of their lower mids range. This bass-bleeding competes with lower mids such as lower vocals and could make this frequencies somewhat congested or lacking clarity in their sound. Higher mids sound sufficiently crisp but not harsh.

With an EQ lower vocals become more energetic and clear; mid-bass bleed is noticeably less present. Higher mids can risk to become forward and exhibit frequent harsh peaks.

H

Highs & Treble

The QKZ X3 highs have good-enough brightness and are able to resolve a mild amount of detail. Piercing highs do not show up but some intermediate sibilance could arise at times. Do not expect muddy-dark highs from them but neither forward and fatiguing highs.

An EQ makes their highs much more open, clear and brighter with also some additional detail resolved; some empowering of their sibilance will happen.

Sound Leak

The leakage level of these QKZ Earphones is a bit stronger than on many average earphones but this does not mean that they are unusable, they will be slightly more perceivable by nearby people if you listen to music at a very high volume.

SI

Sound Isolation

If you want to get a partial perception of your environment while listening to music at a moderate volume, the QKZ X3 could be good choice. Instead, if you want an absolute disconnection from surrounding noises they may not provide as strong isolation as some other earphones that you can find in our Scores Comparison Page.

Comfort

The QKZ X3 have a bullet form factor, shape that almost every time has proved to offer a very comfortable fit. In fact, the X3 provide a secure and pain-free fit inside the ears for long lasting listening sessions without worries.

EQ

Response to Equalization

The response to our different custom EQs applied was very, providing few cons and a strong makeover of some audio frequencies such as sub-bass (which gained a crazy level of depth), lower mids (becoming much more clear and removing most of the mid-bass bleeding and congestion) and highs (overall turning into bright and open)
