Here's my LZ A6mini impression on the 9 extra tuning filter options that come with the A6 flagship model!

9-tuning filter selection kit
A week ago I bought the 9 tuning filters that comes with the LZ A6 flagship IEM as a separate purchase through the LZ store on taobao and it was well worth it! I was amazed that after chatting with them for a price, they decided to sell them to me at 150 yuan (around $21 US dollars)! This was truly a bargain and "done deal"! But, once I received them, that's when the real fun began! Out of the 9 tuning filters, 4 of them surprised me and stood out the most. The other 5 were just either okay, or a miss for me. So, I'll be writing my quick impressions on the tuning filters according to the 3 groups below with particularly 4 different tunes that turn my A6mini into a multi-sound signature deal breaker!
I will list them by "group" according to the picture below and write my impressions on their sound signatures, "thumbs-up"

, or "thumbs-down"

...
GROUP A
10hz-40khz
"RED is very impressive
" 


BLACK

PROS: They are "balanced" with deep sub-bass and excellent MID's and detailed highs.
CONS: Smaller soundstage when compared to the black tuning filters of the A6mini's.
RED


PROS: They are "U-shaped" with deep sub-bass, laid-back clean MID's, and detailed highs.
CONS: None!
BLUE

PROS: They are "neutral" with deep sub-bass and forward clean MID's and clean highs as well.
CONS: Can sound a little harsh at louder volume.
GROUP B
15hz-30khz
"All three tuning filters fail to impress
" 

DARK-GRAY

Deep overall bass, midrange focused with recessed highs.
CONS: Failed to impress with too much bass and MID's.
PINK

Deep sub-bass with recessed MID's and highs.
CONS: Failed to impress with too much lower bass.
GOLD

Deep overall bass, midrange focused and lower treble focused.
CONS: Failed to impress with too much overall bass and midrange.
GROUP C
20hz-20khz "SILVER is OK"


SILVER

PROS: They are "balanced" with nice deep sub-bass, smooth MID's, and pleasant highs.
CONS: At higher listening levels it can get harsh according to different songs or genres.
DARK-BLUE

Deep overall bass, recessed MID's and highs.
CONS: Failed to impress with too much overall bass.
PURPLE

Higher MID-bass and lower midrange presents with recessed highs.
CONS: Failed to impress with too much MID-bass.
* NOTE: After further testing and evaluating, I concluded that even though the tuning filters that come with the LZ A6mini (black, red, and blue) might look exactly like the ones that come with the LZ A6 9-tuning filter kit, they are actually tuned differently according to the "frequency specs" for the A6mini (15hz-35khz) versus A6 (10hz-40khz). They do sound different from each other. So, you might want to keep that in mind, even though both the A6mini and A6 carry the same set of colors pictured below!
*
Conclusion: My favorite from the LZ A6 9-tuning filters are the RED filters for its amazing U-shape sound signature resonating plenty of lively sub-bass, MID's, and hi-end details through my A6mini's. While, in the other hand, my favorite from the LZ A6mini 3-tuning filters are the BLACK filters providing luscious and well controlled balance with plenty of hi-end details throughout the whole spectrum as well on my A6mini's. Both tunings filters make the A6mini's as one of my top IEM contenders I've ever had the privilege to own.
Glad to display some tuning fun!
