"female vocals really shine on this set"
"if you like the Harman target, this is a legit end-game level set. ... It matches Harman almost exactly ... If you like Harman, this is a one-and-done set. It's THAT good."
"I really like treble to the point where they r sibilant. ... The treble details is just great"

"There's good space in the sound and it's good for gaming. ... if you're playing more immersive single player games (City Builder, Stardew, Monster Hunter, God of War) there's enough immersion to feel the weight and impact of key moments."
"for media and games, the contrast is top notch, way better than something neutral imo."

"Supermix 4 are the most comfortable IEMs I've tried"
"The IEM itself is made of resin with a metal faceplate, and being made of resin it allows for a comfortable fit. ... Also SM4 is properly vented with two vent holes, something uncommon in hybrid IEMs. This helps equalize pressure inside the ear, making it more comfortable for long listening sessions."
"Comfortable"

"supermix is great for gaming but also everything else."
"For gaming and or just big sound the supermix 4 is best"
"Supermix4, top end being Kiwi Astral, Ziigaat Crescent, Punch audio martilo are going to be the top for gaming outside of spending $450-550 ... life will be perfect afterwords for gaming and everything else, movies even single player games."

"If you know how to EQ, it’s a great set that punches above its price. ... For anyone upgrading from budget IEMs, this is one of the best options without emptying the wallet."

"the nozzles not having a lip and I guess I have oily ears was a bad combo. ... The tips always stayed in my ear when I would take the IEMs off. ... Cleaning the ear tips twice a week didn't help all that much."
"Size can matter also, I have SuperMix 4 also, they can handle busy tracks very fine, but they are big and it's an issue for my ears."
"I don't know why the right side of my SM4 tends to pop out of my ear, I think it's because of the shape."

"The first flaw is its super slow attack on bass notes. ... Bass notes are almost slurred into."
"It gets shouty and bright if I increase the volume to get more bass so I only listened at mid volume when I had it."
"Bass attack and decay are slow/slurred"

"supermix4 hurt my ears, too much treble for me ... I didn’t think the supermix 4 sounded much better, but the highs were much more aggressive. I played for 1/2 hour and was in pain."
"everything is just super high pitched n supermix and genuinely unusable just because of how nassally and unnatural it makes female voices sound. ... And after a few days I just realized how ear piercing and unnatural the supermix was and so that was kinda it, I didn't wanna use supermix for music anymore."
"I found the SuperMix 4 too bright and fatiguing until I tamed it a bit with SpinFit W1s. ... (Otherwise, I could only listen to the Fall Out Boy discography for ~30 minutes. No such discomfort with my other IEMs.)"

"I'm not a fan of Harman Target’s midrange presentation. It sounds both shouty and thin, whether for male or female vocals. ... The 200Hz bass tuck, combined with the elevation in the 3-5kHz range, makes it annoying to listen to. ... SM4, however, is the complete opposite of my taste, tuned to sound cleaner and analytical in the midrange. ... But the 200–300Hz dip is still an issue, making everything sound thin."
"I dont like the supermix 4 because of its piezoelectric transducer. ... You can immediately hear when it sets in and it ruins the entire mix."
"The Supermix 4 when using it for general video watching. The mid scoop really messes with vocal audio."

"No way supermix4 is neutral ... It was far from neutral. It sounds v-shape imo"
"The SM4 is also nice if you don’t have a shitty source."
"I can can see where you are coming from.. As the sm4s get harsh on some types of music."

1vendetta1 1.0I have Linsoul Supermix 4's and can recommend them, but let's just say my Beyerdynamic DT MMX 330 Pro's are better for longer playing sessions. The switch from a headset to IEM's can be quite difficult. I try to stay clear of ''gaming headphones'' in general.
a1rwav3 1.0They have been, for a long time... I still use them sometimes when I don't have my blessings 3...
A7atsuki 1.0Well I own supermix 4 : its is highly technical thats for sure …. ( not a VERY audiophile listener but have interest in this hobby ) … thats the first thing I noticed about them thay they are hight technical… very detail can be heard …. It lacks midbass … though not that fan of too much mid bass so its ok… can’t fault vocals…. Vocals seems great … soundstage seems really good for price point
They are fatiguing to treble sensitive people
abc133769 1.0planars are renowned for their clarity . typical planar tuning makes vocals come off as sounding metallic though but ymmv something liek the simgot supermix 4 would be great though. hybrid with harman tuning, female vocals really shine on this set
supermix is a good set yeah. usually pure planars like s12 pro aren't rec'd for fps gaming cause many of them have very boosted higher frequencies which can effect staging, not sure how the ultra's hold up though but many use and enjoy the supermix for gaming
simgot supermix 4 would work very well
Afraid_Clothes2516 1.0Super mix 4 are very good
Altrebelle 1.0There’s a method to the madness…at least for my case. I didn’t wildly trust any “professional” reviewer…I got a few (3) of the community rec’d IEMs…to see if they’d suit me (fit, sound, curiosity) Think the total I spent on those was less than what a Hexa would have cost. I, too, came from BT devices…Beats Studio Pro, Beats Fit Pro…I was done with all the BT junk. Didn’t bother with BT hooks and dongles and such. Compression…power…it’s ALL lacking. Anyway, AFTER listening to my 3 sets for a bit…I went back to “professional” reviews on YT. Watched the review vids of those IEMs…and decided on whose views and opinions I aligned with. From there….I was able to make slightly more informed purchases. Yes, it’s usually best to test drive audio gear in person…and buy from a local outlet with a reputable and dependable return policy. For some, that is not possible. I have disposable income…and can afford several sets of Hexa or even the Supermix 4 on a whim. I didn’t think it was sensible to dive in when there are cheaper AND community recommended sets to try. As for BT…if I’m going to use BT for convenience…I would stick with the usual suspects instead of introducing dongles and ear hooks. BUT…that’s just me
Aruiu 1.0The Supermix 4 when using it for general video watching. The mid scoop really messes with vocal audio. The Blessing 3 for how bright / sibilant and clinical it was. I think these two are my favorite IEMs in terms of looks and design, but their sounds were disappointing.
AtigBagchi 1.0While I probably understand where you’re coming from, neutral is at least mathematically represented as a flat frequency curve. But I agree. I have pretty solid studio monitors at home. I thought of complementing it with a somewhat reasonably priced simgot supermix 4 since the curves seemed more Harman like. While it is true to tuning, I’ve realized I care a lot about transient response (spoilt by my other setup) and imaging, not much about soundstage (again influenced by near field monitors). And while the iem does well in imaging, the transients are just not upto mark. But both have their sweet spots depending on how I feel that day
My home setup is weirdly enough a genelec 8331 paired with a WiiM pro streamer via studio standard cabling (mogami, neutrik, belden, etc). While it’s in an untreated room, I feel it’s very very neutral in its representation. My iem is a significantly cheaper simgot supermix 4 with fiio ka11 dac amp (important to know since the iem has pretty low impedance). When I hear songs in them, both the bass and treble seem very boosted much like their curve being Harman like. And they generally sound louder too. Not hexas but still calling out. What I’d rather struggle with if I were to use my iem to mix would not just be non neutrality and higher bass / treble but also poor transient response.
B1ker1 1.0The Simgot supermix 4 are amazing gaming iem especially for footsteps in shooter games for around $150. Unfortunately not on sweetwster tho just checked, sorry
