    Introduction

    Paiaudio is a brand from China, specifically from Shenzhen. It specialises in the manufacture of Hi-End headphones. The DR2 is a model in the Dynamic series. Paiaudio also has other series: Flat Earbuds, Balance Armature and Hybrid Earphones.

    The DR2 are IEMs made of transparent resin, with a really ergonomic and beautiful design, built as gems of high resistance.

    Packaging

    The box where the DR2s come from is a small, transparent methacrylate box. The IEMs are embedded in a foam base. Under it is the cable and a bag with two pairs of grey silicone tips and three pairs of white silicone. It seems that the sizes are only large and medium. The last accessory is a clothing clip.

    Although the content is the minimum required and the presentation is very simple and austere, the transparent box enhances the beauty of the IEMs, as it lets you see them almost completely.

    Unfortunately, the accessories do not include a carrying case.

    Construction and Design

    The Paiaudio DR2 have been built entirely in transparent resin, of high hardness. Inside you can see the great dynamic driver. The nozzles are metallic and gold-plated. They also have a metallic filter, of a fine grid. The outer faces of each IEM are translucent, red for the right channel, blue for the left. In the middle of the outer faces you can see the symbol π inside a circle. The gold-plated MMCX connections are completely embedded in the resin. The set is very compact, strong and durable in appearance, as well as beautiful and very attractive.

    Adjustment and Ergonomics

    The adjustment is simple and excellent. The nozzles are long, allowing you to play with multiple tips to find the best seal and sound. Depending on the size of the tips used, the insertion can be superficial or medium, adapting to the taste of each one. All this thanks to the construction of the nozzles.

    Due to the highly ergonomic design of the capsules, the fit is outstanding and movement is minimal.

    In addition, the level of insulation is remarkable.

    Sound

    Profile

    The profile of the Paiaudio DR2 is in clear V, focused on the sub-basses and in the high mids. The highs are really smooth, but sharp and detailed, although the roll-off from 4.5kHz is noticeable. Then there is a slight rise above 9kHz that brings air and clarity to the whole.

    Bass

    The focus is clearly located in the sub-bass zone, as from 40Hz the curve gradually descends to 700Hz. The result is a markedly deep sound, which enjoys a very important sub-bass hit. The rest of the area doesn't feel so powerful, yet the bass doesn't sound orphaned or incomplete, but is very enjoyable.

    The speed of the lows is remarkable for the price range. The color is also very realistic and the body it provides is very suitable, meddling little in the mids, due to its special focus on the lower area.

    It is true that the width of the area is not large, compared to other IEMs with more punch in the center of the bass. But its special characteristic shines in many genres, it is surprising how the DR2 provide depth in musical pieces where the basses are even subtle.

    Paiaudio DR2 07.jpg

    Mids

    As I have already commented before, the low mids go down to 700Hz, to go up as a W between 2kHz and 4kHz. With this profile the DR2 suffer from a certain body in the lower part of the mids, sounding somewhat backward or sunken, but never dark or congested. Thus, male voices can be perceived somewhat more distant and thin, even something similar can happen with female voices. But luckily the clarity and naturalness is quite good, although the relative loss of power in the final area of the bass, makes this area sound slightly hollow.

    However, the rest of the mids shines clearly, with a good cleanliness and clarity, remarkable level of detail and separation. The clear enhancement between 2 and 4kHz makes the mids sound more coherent than its graphics might initially suggest. The definition and resolution of the area is even surprising, despite the a priori imbalance.

    In short, mids are better than one might expect by looking at the frequency response.

    Treble

    The treble is smooth, without obvious enhancement, with a slight peak above 9kHz that provides brightness and air, without causing stridency or wheezing. The resolution and definition is remarkable and gives the whole a good level of separation and clarity. Suitable for all those who are looking for a sound with "safe" treble, without losing detail or clarity.

    Scene, Soundstage

    Pure V-sound doesn't have to be at odds with a lack of scene or separation, even if the price range is the current one, around $50. The scene enjoys a good width and depth, propitiated by the excellence of the sub-bass. The cleanliness and clarity of the sound, as well as the lack of congestion, produces an almost remarkable separation. The instrumental recreation is shown at the same level and the feeling of three-dimensionality is perceptible without a hint of doubt.

    Comparisons

    Ostry KC06A

    The KC06A offers a warmer sound, with more present and closer voices, with more body, but with some darkness. The profile is more balanced from bass to mids. While the DR2 sound more V, with that deeper sub-bass and finer voices. However, DR2 has a crisper, brighter, more sparkling midrange. While the KC06A are more contained and smooth. Such smoothness is common throughout the Ostry range and detracts from a certain capacity for resolution and detail. However, the Paiaudio are perceived clearer and offer greater separation. Despite all this, the low treble in the Ostry are clearly enhanced compared to the DR2.

    The KC06A has never been characterized by offering a very wide scene, its more frontal sound penalizes this aspect, as well as the feeling of depth. In the DR2, there is a greater openness, a more open scene, greater depth and better instrumental recreation.

    Fiio FH1

    Other warm IEMs, with low and mids close and very soft highs, are the Fiio FH1. The differences here are quite noticeable. The curve of the FH1 is clearly flatter. The lower part of the Fiio is more linear and thicker. The mids, except in their upper part, are more compact and balanced, but more congested, veiled and dark, bordering on lack of air and cleanliness. The character in V of the DR2, with the central zone of the mids more sunken, favors the decongestion of the sound in this zone, although it reduces body, being perceived something hollow in the comparison. In this zone the FH1s overwhelm in presence and density, becoming saturated. However, there is a clear lack of air, light, brightness and separation, characteristics that DR2 do provide.

    Paiaudio DR2 vs Fiio FH1.png

    The FH1 are IEMs with a low zone quite palpable, more homogeneous and not so focused on the sub-bass. But the sound is not as deep as the DR2.

    Although the Fiio has a BA driver, this is not used to offer detail or a great resolution, since all the sound has a great compaction and density. The detail is clearly more noticeable in the DR2 and its sound has higher resolution and separation. The scene, therefore, is greater, with a larger depth. Meanwhile, the FH1 have a vastly frontal sound.

    Conclusion

    The DR2's are really very sub-bass. But not only. I'm learning to appreciate more balanced profiles, with higher resolution mids and sharper, more detailed highs. But when I hear IEMs like DR2, I go back to my origins and remember primeval sensations that evoke the power of its lower zone. But, I insist, these IEMs offer quite a bit more, as they have a surprising middle range for such a pronounced V. In addition, they have a good dose of clarity, separation, sharpness and detail. Finally, Paiaudio has given these IEMs an excellent, beautiful, precious and ergonomic construction.

    The DR2 is a sub-bass gem, which shines beyond.

    PAIAUDIO DR2 / OEM | 1*DD | Rating 8.4
    Written by DallaPo
    Published Mar 16, 2019
    4.0/5,
    Pros - powerful bass, natural and lively sound, design
    Cons - bass can be exaggerated, presence of lower trebles
    Intro
    On my little round trip through the Chi-Fi universe I came across a "little" IEM pearl, which I don't want to withhold from you. It is a DIY-In-Ear, which is also marketed by PAIAUDIO as DR2. Nevertheless it is an OEM-IEM, in which the respective "manufacturers" can engrave their logo. For example, my copy has the PI engraved (PAIAUDIO), but I have already seen other logos on it.

    Handling
    The extraordinary thing about the DR2 is that the case is completely cast in resin. And when I say complete, I mean it because there's no cavity. The dynamic driver is basically preserved in the case and only has a small tube outside to "breathe". For this purpose, another, thicker tube leads to the sound opening. All this is completely surrounded by resin. There are no air bubbles, which speaks for a good workmanship/production. The resin piece is also free of coarse unevenness and rough spots.

    The DIY DR2 does not only look like a custom IEM, it also wears like this. Very ergonomic and secure in fit, it should fit almost any ear despite its size (exceptions confirm the rule).

    I can't say too much about the cable, because I decided to order the version without cable, because you can save another 7 € (18 €). Nevertheless, according to the pictures it is a standard MMCX cable made of copper, which will surely serve its purpose.

    With a correct fit and ideally foam tips, you can achieve a really good isolation. Since there are no other openings except for the small air hose and we therefore almost speak of a completely closed case, nothing of the music penetrates to the outside, there is also no cavity in the inside and so the sound enters our ears directly without detours! However, there is little or nothing to come through to the inside, which should please especially musicians. But you should be a bit more careful with the in-ears, because resin is not quite as robust and therefore more susceptible to external influences, which could affect the optics in the long run, rather than the function.

    Sound
    Powerful, natural, lively and dynamic with a slight tendency to exaggerate, the DR2 describes quite well.

    The bass has an incredible impact, which will put a smile on every bass lover's face. It plays quite linear from top to bottom, while the sub-bass is a bit pushed again. This allows not only to hear the bass to its full extent, but also to feel it. The DR2 gives every genre a good ladle of bass, which tastes good because it is well seasoned, but not salty. Bass guitars sound so energetic and powerful that you inevitably look for songs in your library where they stand out - AnnenMayKantereit - "I'm fine (live)".
    Hip-hop is also excellent for the DR2. Due to the low bass there is a lot of taste behind every song. Amazing is the fact that the bass remains controlled and has texture. Sometimes he simply means it too well and starts to get a bit muddy when the music already has a strong bass part.

    If you now think that the mids of such a bass machine go completely under, you are mistaken. Of course the bass doesn't manage to leave the mids untouched, but they benefit with a pleasant warmth and a voluminous body. They are clear and detailed and manage to give the bass slogan without having to fight too hard against him. Here as well we have a basic naturalness in sound, especially when it comes to voices. Guitars sound crisp without becoming shrill and trumpets have a natural timbre. In addition, the mids are almost lively and don't hide behind the treble and bass, even if it's a V-signature. However, you should keep an eye on the volume, as the mid-range in the upper range becomes a bit exaggerated, which can be fatiguing, as they have their highest peak between 2 and 5 kHz.

    After the mid-peak, the frequency response drops down and the treble returns with a smaller increase of about 10 Hz. They have thus seen an above-average expansion in the price segment and for a single dynamic driver. Here, too, the keyword is natural, although they could be more present in the lower trebles. They are airy and playful, even if they don't show much brilliance now. But there are no sibilants, or a sting in the ear. They can even handle "problematic" voices like SIA's without any problems. They don't reveal every micro detail, but the level of detail and resolution is more than convincing.

    The stage is in a good average position as far as the depth is concerned, but the width is quite respectable. The separation is also very good, because instruments rarely overlap (this is partly due to the bad mastering) and can be easily followed.

    Outro
    I am more than surprised and enthusiastic about the sound of the highs, as well as the rest. The bass can take the mountain pines off, but it can also exaggerate. I think if I were to listen to music all day with the DR2, the bass would be too much for me in the long run, but for an extended listening session in between it's just fun. The mids are lively, the voices authentic and the highs convince with their clear, unagitated and detailed way.
    If you are looking for some natural, bass intensive and dynamic sound you should take a look here. I also recommend these IEM musicians, who are not looking for absolute, analytical neutrality, but who also need some fun

    That's exactly why I love this hobby so much, because now and then in-ears come along, which you don't have any expectations of and are so positively surprised by.

      I might wait for Ali Express to have another big sale and grab the T2s for £20 then, thanks! Otherwise if I get bored... might as well try the DR2s :)
