Unboxing and first impressions

Classic YinYoo box here: a cardboard with a carrying case and various accessories inside (buds, cable, 6 pairs of silicon eartips: 3 wide bore, 3 small bore). No foam tips, no cleaning tools. A close experience to the V2 model by the same brand. Differently from the V2, the cable here is worse (strange, because the price is higher) and the standard is MMCX and not 2pin. I know for sure that now, if you buy the D2B4, they ship them with a better cable, which is closer to the BGVP DMG or NiceHCK M6 cable. I don’t mention those two models randomly: they share the same driver configuration and a similar build quality with these YinYoo. I don’t like my cable (remember: I have the older version), so I switched to a NiceHCK cable which is identical to the M6 one (it’s actually the P3’s cable); I’ve also tried the upgrade 8 core copper plated by the same company, but I’d rather use it with my NiceHCK M6 (because – spoiler – I prefer them). What’s not so convincing about these earphones? Despite their amazing look and build quality, the isolation is not that good – while that is a main feature on the counterparts I’ve mentioned.

Sound

My files: DSD, FLAC, ALAC, MP3, M4A

My music: “Colour the Small One” by Sia, “Djesse Vol.1” by Jacob Collier, “Where are You?” by Frank Sinatra, “Ghost Stories” by Coldplay, “O” by Damien Rice, and many other tracks by Queen, Billie Eilish, Pink Floyd, Genesis, Radiohead, …

Given the same driver configuration as the BGVP DMG and the NiceHCK M6 (which are very similar one another), I thought the D2B4 were close to them too. It’s not really true. The sound signature is kind of comparable, with a full bass, nice mids and a decent treble. Other factors make them sound different: layering is a bit worse, soundstage is less wide – yet very deep – and detail is not the main focus here.

Bass: more than enough, for a balance lover. Sub-bass is decent, mid-bass is prominent. The problem is that it sounds a little bit muddy. The seller said the new cable can improve the sound, but I’m not really a believer of this (and, as I’ve said before, I’ve already replaced it). I’m not disappointed, I could even expect something like that. But I’ve heard the YinYoo V2 and their punchy yet controlled bass which I find amazing, so I may be right by expecting something more refined here. I really appreciate how this dark background matches with sharp recordings (like “A Fever Dream” by Everything Everything), though: the mid-bass invades the midrange, but many main parts are on the treble side, so you get as a result a comfortable, non-fatiguing experience.

Mids: they are recessed, I can’t deny they are under the pressure of that enhanced mid-bass. Male vocals feel undertone sometimes, but this is the only real disadvantage of this kind of tuning. I like the instrument separation and I hear a decent detail here. Female vocals (especially the higher ones) are airy and crisp. I would have expected a better layering, because sometimes I feel a lack of clarity whenever the mix is full of instruments. You can distinguish them (we are talking about decent specs), but they might be clearer in their reproduction.

Treble is good for my personal taste. I don’t like picks of any genre, so this relaxed high range is perfect for me. So, the overall frequency response that I hear is kind of L-shaped. Detail, vocals, instruments (especially drums) are really enjoyable on the high frequencies. I don’t have any sense of exaggerated effort, neither on the sub-bass or the top-high. If I had to correct something, I would take the mid-bass down a bit, because it’s very “covering”, too much sometimes.

The soundstage is average, the imaging is good. I hear no particular holographic atmosphere.

Comparisons

BGVP DMG / NiceHCK M6: I prefer these two over the D2B4. The shape is better for isolation and stability, the provided cable is better (but the new D2B4’s one is kind of identical). Speaking of sound, I hear a clearer bass on DMG/M6 and a better detail and layering. But I have to consider the price that’s different. D2B4 costed 130€ (like DMG) but they are now 80€ (a little bit less than M6). The best deal here is NiceHCK M6: they have the same sound as DMG (for me, they may be even better because they might have less sibilance, if I hear correctly), but better accessories and the most appealing price for performance. Despite the similarities between the new cable of the D2B4 and the other two cables, the factory which produces these YinYoo models isn’t the same as the BGVP/NiceHCK.

 

Tin HiFi T3: I’d rather them too. Better cable but worse accessories, same level of build quality. For me, the two drivers of the T3 are better tuned than the 6 drivers of the D2B4. There’s not so much to say here, T3 are difficult to beat even for twice their price. I think D2B4 are nice for their price, but they are not the best product I heard by YinYoo for sure (V2 are absolutely amazing, and Y1 too, for my taste). The starting price of D2B4 was too high; now that they are cheaper, they have more sense. But I wouldn’t choose them, honestly. I have to say the D2B4 are more comfortable to wear, the T3 (like every other Tin HiFi product) are a little bit too large for ears on the smaller size.

Conclusions

I feel like YinYoo is trying to produce a lot of different products, following the best trends of Chi-fi: V2 are a great counterpart to the Tin T2, while D2B4 aren’t that solid against the BGVP DMG. Now they are out with their Topaz (which I feel it’s like an IKKO OH1 contender), and we will see if they are worth it.

I try a lot of earphones. Sometimes valid products don’t really appeal to me like they could. In the end, this product is solid: really good accessories, capable sound, nice build quality and now even a good cable. I’m more into balance than fun, and the D2B4 are far from being balanced. I would recommend them to casual listeners, occasional bassheads, but if you need that sub-bass punch, I think you have to search more. These, to me, feel like the On Ears I’ve reviewed by 1MORE (here, in Italian). They don’t fail anywhere, but neither they shine. If you find a really good deal, you can get them and be satisfied, with a flavor of BGVP DMG and nice performances. Just be aware that the soundstage is limited and the instrument separation could be better due the enhanced mid-bass.

Unboxing and first impressions

If you are familiar with YinYoo and NiceHCK, you will know what to expect by their packaging. Here we find a cardboard box, which contains a carrying hard case, which in turn contains the earphones and the eartips. Very simple, but functional. The cable is not removable, and it has some controls on the wire (one button, which can play/pause and skip tracks with different actions). The button has a good click and it works perfectly. There’s a nice working microphone too. The problem is: I really don’t know which earphone is the right one, because they are both marked as left. With a simple test, I understood the right one is the one with the wire controls. Apart from that, I love the design, the materials and the build quality of these earphones. They are made of metal and ceramic, and the cable reminds me of the Meze 11/12 series. There’s a mesh filter, which I believe it’s made of tissue. On the connector and on the Y split there are some reinforcements, so I’m 100% satisfied with the build quality and I’m not worried about the resistance of these buds. The fit is average, for my ears which aren’t easy to match with classic in ears. With some foam tips they are more stable. It’s a bit better than the fit I had with the Meze 12 Classics, which I really cannot wear without them falling.

I don’t think these earphones have been successful. I didn’t read any reviews (because I didn’t search, but even on social networks nobody seems to have shared his review). So, I guess it’s something that sounds unusual and doesn’t encounter people’s taste. After trying these earphones, I’m not sure if this is true. I liked them. They are cheap and they are meant to be considered a first buy, or just an upgrade from your phone’s stock earphones. But even by choosing these consciously, for me they would be very nice sounding. They are, actually.

They can be considered V-shaped. It’s nice to have this signature in a consumer-oriented pair of earphones. They can suit a lot of genres and answer to the needs of everyone. Sure, I’d prefer a flat signature if I could choose, but I’m perfectly fine with this one. Especially because the driver (a single dynamic) has a really good quality and the tuning is good. I tried the V2 by YinYoo before, and they still are one of my overall favorite earphones. It seems that these ones could be good too, in a different way. I don’t generally like non-detachable-cable earphones, neither classic in ears (I’d rather have an IEM style); but the general quality make me appreciate these Y1 as a whole.

The first thing I liked is the soundstage: I generally like a wide, extended perceived stage; the Y1 are not crazy wide, but they don’t feel congested and the imaging is pretty precise, so you have a sense of immersion which is enjoyable and far from the bad holographic try of the KZ ES4, for example. The sub-bass is smoothly reached and give a nice background to these earphones; the mid-bass is luckily controlled and it doesn’t fall on the midrange, which I’m surprised of, because cheap earphones tend to have issues on that area. Mids are a bit recessed, but lively enough. The instrument separation in that area is better than average, and there’s a good layering. The best thing of the whole play is the sense of space, which feels true. Vocals are relaxed, not sharp at all (which I like), even on tracks which are often critical with some sets. Treble is very nice, with nearly no sibilance nor harshness. There could have been the classic pick on the upper midrange to give a touch of color and clarity and widen the stage; there isn’t, but I don’t miss it, though. It could have ruined this relaxed tuning, which at the same time doesn’t miss any energy.

Comparisons

I’d like to compare some models differently from the other times. Considering this is barely “moddable” (not having a removable cable), I will put them face to face with other similar earphones in their concept.

BGVP Sidy DM3: really capable, but immature. Y1 are better, even though DM3 (which are pretty old I think) were trying to surprise with vocals and space. The tuning was really bad, though, because they wanted to enlighten certain aspects, by sacrificing others – maybe more important. So, the tuning is very strange on DM3, but you can like them as you like, for example, the Simgot Meeture MT3: for vocals. Y1 are an overall better choice, because they are tuned in a more mainstream way.

Meze 12 Classics: they are better in an absolute way, but considering the price range I’d go 100% on the YinYoo. Same qualities on the outside, different ones on the inside. I don’t love the darkness of the 12 Classics, neither their congestion. Y1 are closer to my taste.

ADVANCED M4: considering these are among my all-time favorites, it would be hard to make them lose. They are pretty different in their sound signature, much flatter than the YinYoo. I won’t say the Y1 lose here, though: they are cheaper and they are absolutely worth the money. I prefer the M4 because they are more suitable for my needs (music production, ecc..).

Conclusions

Even though they don’t make the best impression with that poor quality control (both buds are signed as left), the YinYoo Y1 look gorgeous and they are perfectly crafted with premium materials. I like the sound too, for me it is solid and mature enough to suit the needs of the majority of people. The stage is impressive, not for width but for precision and imaging and they really provide a pleasant overall sound that I couldn’t but recommend.
