So I finally received my S8 from black Friday sales after approx. 2 weeks. Originally ordered the S8P but got the S8F instead, oh well, don't really mind it. Anyway, back to the IEMs. First thing I noticed is that they are really sensitive. I can hear a noticeable hiss on my Dragonfly Red and my ifi xdsd even with music playing. I had to use IEMatch on ultra when using it with both. No hiss on my phone though (S10). Though oddly the jack connection is really finicky with it. The volume becomes soft or loud depending on how the cable feels whenever it gets plugged in. Anyone else experience this? It's fine with IEMatch though so maybe I need to get a new cable or get a replacement cable from linsoul.
Now some quick impressions on the sound.
BASS:
These made me rethink about how much bass can be pushed out of a BA driver. Their kind of DD like in quantity with the speed of BA drivers. It has an addicting low end rumble that doesn't mess too much with midbass impact. Overall great bass extension that is respectably well textured and tight. (take a listen to "DMs by SNBRN". I can almost feel every "fart" from the bass rumble lmao)
MIDS:
I kind of suck at describing mids, it's just not my forte. Vocals on the S8F sound good and you can pick up a good amount details like when singers smack their lips and all that jazz. Trumpets sound incredible with these IEMs although I feel like the timbre of stringed instruments like violins are a bit off in the lower octaves but it's not a deal breaker. Overall though there is good separation, resolution and decent clarity. Lower mids can get a bit congested depending on the complexity of the song though.
TREBLE:
As a note of warning, I don't mind the treble on my DT770 and DT1770 so take my words with a grain of salt. The S8F have an OK treble extension, their not overly amazing but they are not offensive either. Sibilance is not a big issue with these IEMs and I don't think they are overly bright. There is enoug "air" and the soundstage is not bad. But I keep on thinking they may be a bit rolled-off. Maybe I've been spoiled by my Stax ¯\_(ツ)_/¯.
Overall I think these pair of IEMs are pretty good. If you are looking for an IEM that are well balanced bass monsters that tilt towards a warm sound signature, the S8F should be in your list.
