Great sound, but unmarked cable for L/R.

Edit: found it

I bought and tried them before the thrutears, they honestly didn't impress me and I returned them.
I liked the thrutear zero much better, and speaking of even cheaper iem versions, I found the moondrop chu exceptional so much that I bought two. Great sound for peanuts.

I've had mine for about 3 weeks. Very happy with the sound. I found it's very important to try all the tips. Finally settled on the yellows, really made a difference at bass and isolation of external noise.
I look after them very carefully, if they last six months I would be happy :) Got them at $18 USD on special.
It's overwhelming how many types of IEMs are out there!
What should I try next? (Under $100)

Are you looking for more bass presence or something else?

Ah, I think stay neutral. I have the ifi hipdac which has a bass boost button which works nicely

Most hyped up IEM sets at the moment have questionable tuning and/or driver tech, in an objective sense. I would say under $100 the standouts besides the 7Hz Salnotes Zero are: Truthear Zero, Tin C2, Kiwi Cadenza, Tin C3 and Tin T3 Plus.

Be sure to check the squig databases as there you can compare them against each other. Very useful.

To my experience, the measurements of Squiglink reviewers are from very inconsistent quality. Some are good, some not.

The best Squiglink-esque page is usually the one with crinacles measurements:

Crinacles has the worlds biggest IEM measurement database and his measurements are usually among the best. That said, he limited certain functions to "premium users". ;) So for some things, other Squig databases are better.

Never heard of Crinacle until yesterday. Following him on Youtube. Like his content and humour :)

Got my white Tangzu Wan'er a few days ago and will post impressions here as there was some discussion of this and other sub-$30 IEMs earlier in the thread.

Delivery was very quick, took just over a week. I've had some things take longer to arrive domestically recently! (we have mail strikes here in the UK).

Note on shipping, however: I bought the Wan'er on sale ($15 from $19) but was not presented with the option of free shipping, only $5 shipping, but when I added the Tripowen Zombur cable for $9.99 I could select free shipping. So I ordered the Zombur with the Wan'er just in case the stock cable had any problems, or if I wanted a mic. Looking now, if you add the Wan'er, currently not on sale, to your basket, for $19, you are presented with free shipping. So... the Wan'er is actually more expensive when not on sale? I might have done something wrong, but it's something to be aware of (we are talking meal deal amounts of difference of course).

My IEM reference is Etymotic ER2XR, and headphones HD6XX. My intention buying the Wan'er was a) see what $15 gets, and b) hopefully find a shallow-fit alternative to my ER2XR for when this is unnecessary/uncomfortable e.g. lying in bed.

Cable

Following on from above, I have no major complaints about the stock cable anyway. It looks very nice, The stress reliefs are well designed, and I love the low profile right angle connector which sits flush against my phone when plugged in. It feels soft and not microphonic in everyday use: running a fingernail along it is audible, but walking around with it bouncing against your clothing doesn't transmit any noise.

Cons: tangles easily, no clip, no adjustment ring, L and R cables leading up to the IEMs are quite thin (may contribute to the tangling). Pretty minor though.

I'm yet to properly try out the Zombur cable I bought, but it definitely doesn't look as pretty as the Wan'er cable, especially when plugged in (black fabric braid + transparent white and gold does not go together). Maybe I will like it, but if you want a mic it seems a better deal to simply get the Wan'er with the mic cable, unless you particularly want a separate cable without a mic.

IEMs!

These look great. I think they look even better in person. The faceplate is behind a few mm thick transparent plastic which gives a pearlescent effect in the right light. I don't like the black version from pictures, especially as you still get the white cable which fits perfectly with the white version, but maybe this looks better in person too.

Built entirely from transparent plastic with a metal nozzle (I think, that's what it looks like). I don't think it would withstand being stepped on but otherwise appears it would hold up well. At least it is made in such a way that there are very few things that could go wrong e.g. I've seen pictures of the Truthear Zero faceplate coming off--that's not going to happen here. Reviews have described this as looking/feeling cheap, I disagree.

I have always struggled with shallow fit IEMs and this one is no different. I tried all the included tips, the large wide bore ones were the best but even then I found Final's E tips better because the silicon is thicker so I found it easier to get a seal without deforming it.

Isolation is not as good as Etys but better than my HD6XX. Walking around listening to dense music like metal could mask low traffic sounds without turning up the volume too much.


Sound is exceptional, I perceive it as pretty much just right. I don't believe in the concept of 'technicalities' so don't accept there can be a transducer which excels in tonal accuracy but somehow has deficiencies in 'technicalities', especially as the line usually goes 'but don't expect too much, it's only [insert price below $500 here] so is not the most technical'.

I don't have my own 711 coupler, so going off measurement's by others. There is a lot of variation out there, however, and we don't know who is following best practice. There may be unit variation too. Anyway, most measurements show the Wan'er pretty much matches the ER2XR in the midrange but has up to 2dB increase over most of the bass range. Then treble differs as of course we have deep fit with Etys, though the Wan'er maybe has a different slope in the treble also. Hard to tell with the peaks.

I'm still undecided on the bass. I think the Wan'er is definitely a little too warm objectively speaking, and I've been using a peaking filter at 150Hz of Q=0.8 to adjust this: -2.4dB works well for most songs, up to -3.4 is good but more sounds too thin. Subjectively, the warmth is actually nice on some recordings however. As usual the differences in recordings makes a bigger impact than slight variations in transducer tuning. It's definitely acceptable without EQ.

Additionally, I think Etymotics give you a different sensation of bass due to being shoved so deep in your ear. In short, whilst the Wan'er is at the upper limit of what I think is acceptable bass quantity, if it were a couple dB less that would be fine too.

The mid-range is perfect. EQing in a couple more dB around 3kHz to fully hit that Etymotic target does add a sense of 'bite' or 'clarity', especially to guitars, but I'm not sure it's objectively accurate and it sounds worse on more things than it sounds good.

I think the treble level is perfect too. Like the ER2XR, it's way below Harman, and that's just how I like it :) it simply sound correct. There is something slightly unrefined about it, e.g. sounds in that range can sound less distinct, more mashed together, than I'm used to, which I think is down to the resonance peak inherent in the shallow fit design. I'm spoiled by my Ety christmas trees.

Soundstage schmoundstage

You need a proper desktop DAC and amp combo to feed these enough juice though. Gotcha, no of course you don't! Listening on my phone I barely had to turn the volume up at all.

Some people like getting different headphones for different sounds. I like consistency, and now I have 3 headphones for different use cases which provide broadly the same tonal response.

Overall these are great. If you are ordering something else from Linsoul I would just chuck these in your cart for a try. If you are an Ety believer like me, I would highly recommend these if you want a shallow fit or less isolating alternative.

It would agree better with Harman on a graph. I have a Kiwi Cadenza, which is basically tuned like the Wan'er with some 2dB extra at 3.5KKhz. It sounds tonally correct to me, so your EQ move makes sense. There's some outlier recordings only that sound bad.

Potentially, this is partly what I was alluding to when I said there's a lot of variation looking at measurements from different reviewers. I wasn't going to go into too much detail but, now you bring up the topic, I don't think the measurement from Super* Review is accurate. It's irritating that squig.link doesn't have the Harman 2019v2 target to compare so I've included IEF neutral and the Truthear Zero to show that the Wan'er as measured by Super* Review clearly follows IEF neutral almost exactly and doesn't reach nearly enough at 2.7-3khz to match the Truthear Zero, which I'm using here as a benchmark for Harman in that range.

Take a few other measurements, however, and they show the Wan'er getting much closer to the same SPL as Harman in that region just below 3KHz: Gizaudio, SupOrSalad, almost all the other measurements I looked at in fact.

Granted, it's still below Harman, but not as low as the Super* Review measurement suggests. So when I said EQing that area sounds worse, it's probably because I was going off the Super* Review measurement, and I also incorrectly wrote 'a couple' when in reality I was adding in more like 3.5dB at 2.8kHz, which really doesn't sound right.

Given this, and given my preferences (and my belief in what an objectively correct target is, but that's another matter) align more with the Etymotic target, my impression was the Wan'er very nearly hits that pinna gain peak at 2.7kHz and is only short 2dB at most. Additionally, because this means I like my target sloping off rapidly after 2.7kHz, I would only ever want to EQ a pretty narrow Q=2 peaking filter at 2.8kHz, as before, to help it on it's way, which is actually not massively noticeable anyway.

Additionally this means that the Cadenza wouldn't align with the preference of someone like myself (an etyphile I guess), because the boost is too further up the frequency range, and in fact some measurements I've seen show it to have even less in this 2.7-3kHz region I've been talking about.

They all use some clone couplers and seemlingly arbitrary calibration. Only exceptionsis Kurins uses RA0045 measurements from Oraory1990 and GRAS RA0402 from Resolve

Does Crinacle not use a legit GRAS now too? He doesn't have the Wan'er measured anyway. Thanks for the Kurin link, never seen this one before! Has such a good selection of targets, too. I can't find any information about this 'kurin', is it some discord thing?

Omg no resonance peak too, so much more readable!

It's due to the RA0402 high-resolution coupler, which is, in a way, a more damped RA0045. Technically this makes measurements not compatible with the Harman IE target.

I just received my pair, first impression out of the box was that they fit the ear very well and seem to sit securely. They seem sturdily built, more solid than the pictures had me thinking. I quite like the very soft tips they give you and I am using the blue ones, I'd assume that these softer tips have a lesser chance to hurt the ear than the very stiff ones Truthear give you.

Out of the box I found the treble to be rather... tinny? The treble felt overpowering to the point it hurt to listen to, and they didn't have enough bass which probably helped make the tonality even brighter. While the treble was piercing, I was happy to note that I didn't hear any sibilance.

Gosh, I don't really like trying to describe IEMs and headphones as it just sounds like typical audiofile junk-lingo.

So, I loaded up Oratorys Harman EQ and while that sounded better they were still much too bright. I am still toying with the high shelf treble filters Oratory provides in his EQ, but currently I am ~5db below the Harman pinna gain and that sounds rather neutral to me. But I am not too happy with the bass still, because while it's full but it seems to lack the impact of my other IEMs, the other-other Zero and the Hexa. Using a sine sweep they sound the same in the sub-bass region, but with music I simply notice the impact of lower notes less with this set. Who knows, it might be that I am hearing differences that aren't really there - it does take a while to change both the IEMs and the EQ and my memory might already be wrong by the time I am ready to listen again.

Overall, these things are 20 bucks. If you have EQ available and you are fine with putting things in your ear, they are a no brainer IMO. I definitely prefer them to the ASR darling, the TCZ, as those are simply huge in comparison to the 7Hz Zero. The smaller size would probably mean they have a higher chance of fitting in the ear of more people.
