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.

Hello there. Thank you for the review.

With regards to our Return and Warranty Policy, that information has been stated under our 'terms-and-conditions', which all customers have to read and acknowledge before making any purchase on our website.

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.

Redemption by KZ after the disastrous ASX

In simple terms this is the best KZ I've every listened to and this is indeed the model that might have redeemed kz from their disastrous ASX launch. It has really good tuning with the right amount of bass and mids while keeping the treble under control. It is surprising to think that an all BA set-up can sound pretty much natural in the lows like a dynamic driver. I'd give them props for correcting their mistake and giving stress on good tuning along with plopping more drivers. that combo often doesn't work out well but in this case however it strikes a good balance.
