Art request misunderstood. Sound is wonderful

Rated by overall experience including order processing.
I left the shell color default:clear and chose All-Blue from faceplate, and I got...blue face plate on clear shell. What I actually wanted was one just like the sample photo in All-blue... Embarrassing because I was informed that I will have so-called smurf shell if I do so when I asked via mail months ago. I should have confirmed this to Linsoul and let them know what I exactly want. Tragedy of miscommunication...The fantastic shell build quality makes me more upset.
Sound quality is worth 5 stars. This is the best timbre I experienced from 8BA IEMs. Properly distanced vocal sound very comfortable. I prefer sharper percussion, but It is good enough as it is. This IEM is on warmer side, but strangely, not feeling like muffled or veiled at all. The amount of treble not too little or too much, ideal for long time listening.
I'm enjoying the sound while trying my best not to look at the shell art.

Excellent stunner IEM - Clear, detailed, revealing and musical with sufficient bass punch

IEM just arrived.
First impressions impressive and coherent with other reviews - clear, detailed, transparent with extremely good mid range and sufficient bass punch for all non-bassheads.
Sound-wise they remind me of my Focal Clear headphones i.e. a tuning that I both like and enjoy, and that never is fatiguing even after hours of listening.
If negatives need mentioning, excellent recording quality is a must, and the size of the IEM is not for people with small cavum conchae.

Engaging, Exciting, Revealing......Fantastic

The S8Z's reveal layers of the music I have never heard in my favourite tracks, they have stunning clarity across the board and the option to have the look and feel of your dreams is a welcomed bonus. The build quality is incredible and for the price you honestly cant ask for more.

Linsoul also provides one of, if not the best customer experiences I have had to date.....

To me its a no brainer.....definite buy

Fearless Audio S8Z


Love these. I honestly listen to them as much or more than my Andromeda’s. Beautiful IEM with beautiful sound across the board.

Excellent 8BA IEM with some caveats

Excellent detail, needs a lighter cable, better with foam tips


This set is way too intense

James Demer
Fearless S8Z is a champion but requires well mixed music

The Fearless Audio S8Z was called a detail beast by a well respected reviewer, and I would agree. Here's the thing about details, if they are intentionally in the mix, these IEM's enhance them in ways I've never heard before. If the music is not mixed well, the bad stuff is more apparent and well, the music sounds worse.
I don't believe that sound stage is something that can be influenced by headphones. I believe that sound stage a result of the way the music was mixed and mastered. What the S8Z allows is tremendous separation between dynamic range and frequency that gives the listener the feeling that they are sitting in the music.
With well mixed music, the bass is impactful without being overbearing. It's tight. It goes low. It hits as hard as it should without feeling overdone. In a word it's confident.
The high frequency range is just crazy. I hear the way a stick hits a cymbal like I've never heard before. I don't know how Fearless achieved such control with high freqs but no matter how much is going on up high, it sounds complete but not hot. There is no sibilance. None.
Mids weave themselves seamlessly in the mix and vocal range is equally as pleasing with male or female registers. I've been hearing details like breath, mouth squeaks, and accidental mic bumps that I've never heard before on tracks I've listened to for years.
If you are looking to explore your favorite music in a new way, and hear details that you haven't heard before, this is the set for you.
