Cable: The cable is bit thinner than average but feels sturdy. The jack isn’t straight or L-shaped and is diagonal so it is unique. Both the divider and connector are plastic (hard plastic = divider and softer plastic = connector). The cable feels a bit “rubbery” (easier to tangle and harder to untangle because of it) and I don’t really like that and unfortunately it is non-replaceable.
Build: Nothing special with the build, just a typical MX500 shell. It is a bit shinier due to the red color being a bit glossy, so looks pretty nice in my opinion.
Fit: MX500 shells fits me so it’s good for me.
Comfort: Being an earbud it doesn’t go into your ear canal so that means that there is less physical contact between the bud and your ears. There is not much heat generated and comfort is very good.
Isolation: None, it is an earbud after all.
Setup: Ibasso DX160 (low gain, volume around 44) stock cable, full foams
Lows: The best bass both quality and quantity in an earbud without making the tonality or timbre sound worse. The X6 is very close to the bass in iems which is extremely impressive.
Mid-bass: Metallica – fight fire with fire (01:11-01:52), Needs to be faster and tighter because it is a bit muddy. The (02:55-03:01) section with the chopper is hearable, but the imaging and the instrument separation aren’t very good.
Hiroyuki Sawano – Pretenders (01:18-01:47), quantity is pretty good along with texture, but speed and tightness could be better because there is some slight bass bloat here.
Sub-bass: Djuro – Drop that bass (01:15-01:30), Extension and rumble together with the punch quantity, texture, tightness and speed are all extremely impressive for an earbud. And the tonality and timbre are still great, so the bass isn’t sacrificing everything else.
Will Sparks – Sick like that (03:08-03:22), The punch quantity and texture are amazing. Tightness and speed are also very good so it is fun and clean.
Mids: Very good vocal balancing between male/female vocals and the tonality and timbre is very good. The bass does not compromise the mids either, very good.
Female-vocals: Hiroyuki Sawano – OldToday (01:25-01:52), Detailed and clean vocals without any signs of sharpness (or fatigue) while timbre is top tier, but tonality with the female vocals is a bit too warm and need some more brightness to make it a bit more natural.
Yuki Hayashi – MightU (01:58-02:55), Same as above but the tonality thing also affects the instruments here (as in, both the vocals and instruments needs to be brighter).
Evanescence – Bring me to life (01:18-01:35), Not fatiguing or sharp at all, but tonality needs to be a bit brighter because it is lacking a bit energy here.
Hiroyuki Sawano – Crescent (02:07-02:26), Not fatiguing or sharp at all and tonality very good. Although the instrument
Male-vocals: Hiroyuki Sawano – Pretenders (00:57-01:17), tonality is good and suited for this song. The bass quality could be a bit better though, because there is some slight bloat so the male vocals aren’t as clean as I would have liked them to be.
Hiroyuki Sawano – Scapegoat (00:57-01:17), tonality is really good and bass quality is fine without bloat. The male vocals are as warm and thick as it should be without being too thick/warm.
Treble: Linkin Park – Shadow of the Day (03:24-03:42), The electric guitars are not sharp at all or even fatiguing (a very hard feat to do). Although the male vocals need to be a bit brighter and thinner to be more tonally correct.
Deuce – America (03:03-03:16), Not fatiguing or sharp at all, but is lacking some energy with the treble, so it needs a bit more treble quantity.
Hiroyuki Sawano – Lose (string version) (01:22-01:59), The cellos are very tonally correct and with very good texture. But the violins are lacking some more brightness and texture.
Hiroyuki Sawano &Z (02:18-02:57), tonality and timbre are good and it is quite clean and detailed. But the instrument separation could be better.
Soundstage: A bit above average but not the best for earbuds in this price range either.
Tonality: Excellent timbre as expected from an earbud, but that combined with the tonality AND the bass quality/quantity is something I have never heard before. Spectacular and at this price is amazing.
Details: Good for the price, but could be better.
Instrument Separation: Same as with the details, it is good and acceptable for the price but wished it was better due to everything (non-technicalities) being so damn good.

Good genres: EDM, Trance, Hip-hop, acoustic songs, OST, Rock, metal, very versatile and makes it very enjoyable.
Bad genres: Orchestral, due to the instrument separation it can be a bit muddy on those songs.
Comparisons:
Earbud: NiceHCK DIY MX500, stock cable, full foams
Bass: Djuro – Drop that bass (01:15-01:30), Extends lower on the X6 but rumbles much more on it. Punch is tighter and faster on the MX500 but quantity and texture are much better on the X6.
Hiroyuki Sawano – Pretenders (01:18-01:47), A bit tighter and faster on the MX500, but more quantity and texture on the X6 and tonality is more natural on it.
Metallica – fight fire with fire (01:11-01:52), Speed and tightness are better on the MX500 and sounds much cleaner. The X6 has more quantity and texture but is a bit muddy in comparison.
Mids: Hiroyuki Sawano – OldToday (01:25-01:52), MX500 is much more tonally correct, detailed and cleaner than the X6. Although the instruments are a bit more tonally correct on the X6 due to the warmth.
Evanescence – Bring me to life (01:18-01:35), less fatiguing on the X6, but it isn’t sharp on the MX500. But it is cleaner and more detailed on the MX500.
Hiroyuki Sawano – Scapegoat (00:57-01:17), Tonality is more natural on the X6. But cleaner and more detailed on the MX500.
Treble: Linkin Park – Shadow of the Day (03:24-03:42), Sharper electric guitars on the MX500.
Hiroyuki Sawano – Lose (string version) (01:22-01:59), The violins timbre, tonality, details and texture are extremely good on the MX500. While the cellos have better timbre, tonality and texture.
Hiroyuki Sawano &Z (02:18-02:57), Tonality and details are better on the MX500 along with much more treble air.
Technicalities: Shiro Sagisu – Hundred years war (02:24-02:57), Timbe are equal while tonality is a bit better on the X6 due to the bass extension and it being warmer. Soundstage, details and instrument separation are better on the MX500.
Overall: The X6 is a more musical and a bud that is more “complete” due to the bass being very good (close to iem level), very similar effect where you just enjoy music with it like the Blon BL-03 has in the iem world. But if you want a more technical and cleaner bud the MX500 is better.
Although both the MX500 and the X6 are very different. They are complementing each other so I would recommend having both since they are both at the top of what they are doing for buds in this price range and above.

Overall: The X6 is superior to the B40 in every way and they are similar in sound profile.
Earbud: Turandot DQSM, Stock 4.4mm balanced cable, Double full foams
Bass: Djuro – Drop that bass (01:15-01:30), Extension is similar but rumbles more on the X6. Tighter and faster on the Turandot along with better texture while punch quantity is similar.

Hiroyuki Sawano &Z (02:18-02:57), Tonality and timbre are better on the X6, while it it is a bit cleaner and more detailed on the Turandot.
Technicalities: Shiro Sagisu – Hundred years war (02:24-02:57), Similar soundstage while timbre and tonality are much better on the X6. Details and instrument separation are better on the Turandot though.
Overall: The X6 is pretty much better on all aspects besides the instrument separation and details, and for almost 20 times more the cost. It is a joke. Unless you are rich then sure the Turandot might be acceptable, but then you wouldn’t be here looking at the X6.
Conclusion: The Yincrow X6 is a spectacular bud that doesn’t have the usual flaw of earbuds (or at least as much) where the bass is rolled off a lot and without much rumble to speak of. And if it does have bass quantity then It usually sacrifices everything else for it. The X6 has bass along with the tonality and timbre that you expect from earbuds.
Very musical and enjoyable, as long as you don’t focus much on the technicalities, it is going to please you a lot (like the Blon BL-03 does in the iem world). Highly recommended and even more so for those of you that are more into iems. Thanks for reading.
