"I would say that the resolution and technicalities are probably one of, if not the best in the price range."
"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 is great for gaming but also everything else."

"Supermix 4 are the most comfortable IEMs I've tried"
"the shell is more comfortable and fits well in small ears"
"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."

"I love the supermix for music."
"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 Simgot Supermix 4 was too bulky to have a nice fit."
"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."
"sometimes hurts my ear after long use."

"Everything sounded very artificial ... I didn't like the tone at all ... the notes lacked weight and it was too bright ... I tried them on a Fiio K5 Pro Ess and on a Kiwi Ears Allegro Mini dac dongle and the result was equally disappointing in both cases."
"No way supermix4 is neutral ... It was far from neutral. It sounds v-shape imo"
"If I connect to the iPhone using the apple 3.5 adapter it's all too sharp for my liking."

"The first flaw is its super slow attack on bass notes. ... Bass notes are almost slurred into."
"Everything sounded very artificial ... I didn't like the tone at all ... the notes lacked weight and it was too bright ... I tried them on a Fiio K5 Pro Ess and on a Kiwi Ears Allegro Mini dac dongle and the result was equally disappointing in both cases."
"they have only more bass which sounds terrible."

"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'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."
0n1plug 1.0SM4 is all you will ever need
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
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
Apenut 1.0I’ve been using the Artti T10. For music i like the supermix4 better, but for gaming the T10 is so damn sharp, fantastic.
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
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
betterarchitects 1.0I have the Aful and EW300. Sold the Supermix 4. For gaming and or just big sound the supermix 4 is best but felt clinical. The Aful sounded the muddiest but it's actually not muddy at all, it's just very smooth and is my go to for all day fatigue free listening at work. EW300 is my backup that never gets used. Good all arounder but the smallest sound. These days, I use the Ziigaat Odyssey for music enjoyment.
