Alright, I’m ready to share some quick thoughts on the Simgot Supermix 4 that I’ve recently got in. It’s a tour unit provided by HiFiGo so thanks to them for allowing me the chance to take a whack at one of the newest sets from Simgot!
I’m going to start off this by saying I think the Supermix 4 deserves all the praise it’s been getting as of late. It’s currently on back order at the time of writing this and I can now understand why - This set, at $150 is simply exceptional. From the stellar build quality, to the perfect fit for my ears to the engaging and musical sound coming out of them. I should say that I usually do not like the thought of a Harman in-ear tuned IEM, I specifically avoid them because of the shouty upper-mids and lack of lower mids to balance everything out, not to mention, it’s been done over and over and over again in the budget sector as of late.
I feel like the SM4 is different, though. I feel like they’re an exercise in tuning expertise and hardware control - I cannot believe these things are a quadbrid design - 1 DD, 1 BA, 1 Micro planar and 1 PZT (piezoelectric) driver making these things a stellar example at some seriously awesome audio engineering all for just $150… it’ll be tough to beat imo.
The bass on the SM4 is Sub bass dominant, with a thick sub-bass rumble, followed by a thumpy mid-bass kick giving some fantastic depth to the notes when they hit. The rumble is both textured and slightly boomy, which I do not mind at all. The mids are incredibly clear, crisp and airy without sounding harsh to my ears - They’re both forward and smooth without any weird timbre, which I can definitely appreciate. The treble, while slightly more behind the upper-mids than I’d like, is well extended and refined to a point where micro details and dynamics are great. Another part of the SM4 that stands out to me is the sense of space these things provide - my music can breath, especially when I turn the volume up a bit - It just sounds so spacious and the opposite of claustrophobic.
The SM4s also have a neat little trick up their sleeves - they take to EQ extremely well. I highlighted an EQ profile on an earlier post in this very thread and I implore anyone to give it a shot - if you have a portable source that allows for 10 band PEQ then the SM4 could potentially be one of the most versatile IEMs I have personally listened to as of recently.
If I had to think of cons, I’d say that the upper-mids can be a bit shouty for some folks and even some of the tracks on my playlist can sound a bit thin if the mix isn’t right, so keep that in mind. I’d also like to point out that timbre in the lower treble, around 7-ish Kz can be a little bit of an issue. Playing around with EQ helped me see that.
But overall, the SM4 is an extremely fun pair of IEMs with fantastic SQ and for $150, I’m struggling to find another IEM with such a fun and engaging signature that’s been released as of late. Simgot has proven you don’t have to spend an arm and a leg to have some fun enjoying your music.
Bravo, Simgot. Bravo
Thanks for reading, Gents. I hope everyone has a great day!
