24 Units Top-Level Configuration

AST adopts the 2nd generation High-frequency matrix BA combination designed and developed independently. The combination of 12 balanced armature units on one side and detailed acoustic adjustment significantly improves high-frequency performance, makes the human voice rich, soft, and not harsh, and the sound smooth and natural, bring a professional listening experience.

Streamlined Surface Made of Zinc Alloy

AST owns the precision of the ear shell ±0.03 which reaches the highest rigorous quality standard. The zinc alloy material is polished by five-axis CNC and polished by professional craftsmen, making the surface cover a streamlined curved surface and full of sense of technology.

Comfortable To Wear & Noise Reduction

With a smaller size and ergonomic design, AST is suitable for diversified wearing scenarios. The contour curve of the earphone conforms to the shape of the human ear cochlea, which can also greatly isolate the noise.

AST owns 4 strands of 200-core silver-plated professional earphone cable, retaining the sound of subtle changes, which is the symbol of every audiophile. The 0.75mm gold-plated pin insert and pull structure independently developed expands more usage ways to meet individual needs through replacement and upgrading of cables.

What a letdown

I bought these after losing my KZ ZSXs, reading reviews that the sound quality is among the best if not the best of all KZ IEMs.
But to my suprise they sound terrible, there are virtually no highs, they sound super muffled. Only boosting highs by about 12 dB made them sound okay. My 4 year old 25€ Bluetooth headphones or the ZSX sound much better than this.
The cable and the IEMs themselves seem to have a good build quality, though, so there is two stars.

Great Sound! With some EQ and some Power!

Not worthy compared to KZ ZEX

Physically it looks more costly but could not delivery the quality it claims, especially compared to ~$20 KZ ZEX. Requested Linsoul to return but was asked to pay 35% restocking fee. Interesting and disappointed about such customer experience in 2022. Not sure whether other people feel comfortable about such return policy. Not buy anything from this website any more.

E N'EST PAS FACILE DE JUGER CES IEM, JE POURRAIS METTRE 3 ETOILES CAR JE LES TROUVE TROP SOMBRES, L'ECOUTE EST INTIMISTE ET TRES BASSEUSE ET JE PREFERE UNE ECOUTE PLUS OUVERTE, AVEC UNE MEILLEURE REPRODUCTION DES AIGUS.
PEUT ETRE LE RODAGE EST IL TRES LONG DONC DANS LE DOUTE JE METS 4 ETOILES JE PENSE QU'ILS SERONT PEUT ETRE EXCELLENTS UNE FOIS RODES.

Bass head iem

Bass is killer. Best I've heard to date. Imagine they have even more impact then my Sony MDRs. Wish I'd bought a few more sets when the sale was on, the wait is on for next sale event.

Surprisingly awesome

I didn't expect these to be so versatile musically. But basically everything sounds good in these. There's not much more one could ask for if one is using headphones to enjoy music and not to nitpick the headphones.
