I've been listening to the Shimin Li over the past week and I've got to say, I'm not that impressed with it. Don't get me wrong, it's not bad but it definitely isn't the Heart Mirror killer.
Seeing the first few images and FR's and it potentially being another neutral budget IEM to challenge the Heart Mirror, I decided to get one. Loving my Heart Mirror I wanted to hear if it really was true. Sadly I can say that is not the case, the Heart Mirror is just that one step beyond. The signatures are different, balanced warm or neutral bright, but it also lacks the wow factor the Heart Mirror has. But that doesn't mean it's not a good IEM. When I stopped comparing the Shimin Li to the Heart Mirror and just enjoy it for what it is, I did start to enjoy it quite a bit more.
The Shimin Li has great build quality, good looks and are fairly comfortable. The 2-pin connectors on the cable are the only thing that can ruin the comfort as they have edges that are a little sharp. The cable itself is nice, although the rubber like coating might return to primordial goo in a few years like most of these coatings do. Only time will tell.
The bass is pretty good, it has good extension with pretty good textures. The treble is quite good but a bit of a double edged sword at times. It has good extension, is fairly clean and never sibilant. However it's prone to sounding harsh on some tracks. As a treble head I'm pretty unforgiving about treble quality but the Shimin Li has no big issues here other than the occasional harshness. It could be better but for €35 I'm not complaining. The treble isn't as crisp and clean as the Heart Mirror but when it comes to DD treble quality you just can't beat the CNT. I'll give the Shimin Li some points for trying though. The mids I'm not that fond of, it's rather congested when compared to the Heart Mirror and can at times sound a little hollow. It sometimes feels like it's being held back by something, like there is potential there but it just won't show it. I've tried a few things, but stuff like running it balanced doesn't reveal this potential like it did with the Tripowin x HBB Olina (man, that thing rocks when driven balanced ). The Shimin Li does, just like the Heart Mirror, scale with power, although to a lesser extent.
The detail retrieval is no better or worse than the Heart Mirror with similar imaging, separation and layering. The only difference being the larger soundstage, in absolute size it's pretty close but the Shimin Li has a bigger presentation compared to the more intimate Heart Mirror. Although the soundstage is above average at this price point, something like the CCZ Emerald will beat the Shimin Li quite badly when it comes to soundstage, imaging, separation and layering. Despite having a slightly bigger soundstage than the Heart Mirror, it still sounds more congested and I'm not sure why this is. Might be due to the Heart Mirror having a clean presentation with a nice black background.
The Shimin Li is also sensitive to the tips used. And I'm not just talking about the sound signature here. This kind of tip sensitivity is not something I've had before. The tonality goes, depending on the tip you use, from pretty good to sounding off. Using tips to make it neutral warm completely ruins the tonality, and when you get a decent tonality the sound is more a warm mild V-shape rather than balanced warm, let alone neutral warm. How ever this is only using the included tips, haven't tried any other tips yet. This all leads to the Shimin Li being pretty bad at rock and metal as congestion and poor tonality really hurt these genres.
Overall the Shimin Li is a nice IEM with a balanced warm to warm mild v-shaped sound signature. Easy to listen to for long periods at a time. I could see people picking the Shimin Li over the heart mirror, especially if you can't stand a neutral bright signature. But do know it still has quite a bit of treble, more than most IEM's would have at this price. The sound quality of the Shimin Li is above average for the price but that doesn't mean you can't get better for less. Things have been rather competitive as of late, if the Shimin Li was released a few years ago it would have been one of the best choices under €50. But with the HZsound Heart Mirror, Reecho SG-01 OVA and CCA CRA existing it has some really stiff competition which in turn means the Shimin Li doesn't really stand out in the crowd. At least not with it's sound, golden IEM's always stand out...
Does seem like I need to get the Heart Mirror at some point. Having said that, the hint of warmth in Shimin Li is part of its appeal...I have other bright neutral sets.
Thanks for the comparison!
