    "Without precedent, Xiaomi create a superb sounding Triple Drivers IEM that give you sound from the next level for the price of a cheap T-Shirt."
    Pros - Exquisite U shaped soundsignature with beefy bass, present mids and sparkling highs, good construction, remote control and mic, incredible VALUE
    Cons - If it were sold for 100$, I would say cable isn't very fancy...but at 30$ it's already incomprehensible that the quality is that good.
    Xiaomi have always been ahead of it's time in budget high quality earphones and smarthphone, their goal look like to make accessible for the mass products that was only accessible for wealthy consumer.
    My arrive at headfi and especially my obsession about chinese IEM begin mustly because of Xiaomi legendary earphone: the Piston V2. At this time, the IEM hype haven't really begin in China industry, there were few choice of earphones that promise good sound and durability, the Piston V2 wich I still own and listen too have survive multiple accident (like dropping them in my glass of beer) and sound as good as the first day 5 years later, hard to say that even for pricy earphones!
    Now, lot of new interesting chinese brand (or DIY non-brand) have arrive and can be found on Aliexpress or Gearbest at absurd price, we became too spoiled and can expect out-of-this-world sound for little money, wich is good and bad, because there so much IEM on chinese market that we can be lost and confuse, not all of them are seriously good or have trustable quality check for construction, with the exception of XIAOMI.
    All Xiaomi product are great value, even their 6$ basic edition piston sound good and have good construction, Xiaomi is a trustable brand but, and this is a big BUT, look like imitation and false produt always been a problem that came with their success, it was a problematic fact for their popular Piston V2 and still is as well for most of their other earphones including this one (you can find false hybrid for 5$ on ebay for exemple). One advice, buy Xiaomi products from Gearbest as I do, this way you will have and the best price and the certainty to have 100% original product.
    So, Xiaomi done it big this time! And create a second version of 3 drivers budget iem that can easily kick ass of 100$ earphones if not more. 2 dynamics drivers and 1 balanced armature exquisitely calibrate to give a bassy AND neutral soundsignature with lot of microdetails and fun to it. Not too serious sounding and far from just pop oriented, all frequencies are treated with respect wich make these IEM as much exciting for audiophile that listen to classical and jazz than modern music lover that love electro and boomy pop. Even country or folk lover will find this Hybrid earphones superb, cause acoustic instrument are very detailed. For me, they are the big brother of Urbanfun hybrid that have the bass that a dualdrivers can lack, and a dynamic fun that is very rare to achieve under 100$. Quite simply, the Xiaomi Mi Hybrid Pro HD are a budget dream come true, not only due to the fact you can now have a REAL 3 drivers Hybrid for the price of a pack of 24 beers, but that even at 2 times it's price my judgement about sound will be the same.
    * There are three drivers in each side. Dual dynamic driver+balanced armature driver. Elevate the music greatly.
    *  Using HIFI Graphene diaphragm, improve the sound.
    * Upgraded xiaomi hybrid earphone, It is compatible with Android and iPhone smartphone. Also tablet PC...
    * Built-in clear microphone, have a good calling.
    * Wire button design, adjust volume, switch songs, play/pause music.
    * Wire material also improved, it is made of TPE material and more durable.

    The Xiaomi Mi Hybrid Pro came in a little stylish compact white box that include extra silicon eartips and a little pouch. Simple and elegant as always. P4180140.jpg
    The Mi Pro design are similar to the Piston 3 but a little bigger and with the nozzle in an angle, it's made of brushed metal and plastic and is a little heavy (very little), housing feel very solid and look very good. Cable is standard quality but the remote control with mic is of great quality and work perfectly with my Samsung S3. Jack is made of metal too. Even if cable look flimsy, there a very important quality to it: it do strangely do not cause microphonic noise even if it touch your clothes etc (that's precious!). All in all, these look like more expensive iem. The design with angled nozzle make them very comfortable and easy to fit rightly in the ear canals, it is not prompt to fall and are not over ear.

    For this review I use 3 different DAP: Ibasso DX90, Xduoo X3 & Benjie S5.
    I don't listen music with my smartphone alot (if not never) but I try the Mi Hybrid mic and remote for this review too.
    Earphones for comparaison are PMV A-01 Mk2 wich is an excellent 3 drivers IEM at 80$ (1 dynamic+2balanced armature) and DIY Geek Audio Hybrid Dual drivers (wood iem with 1DD+1BA).
    LOW (bass):
    Round, punchy bass with good resolution that doesn't bleed in the mids are what you get, this isn't boomy at all but have a good weight to it wich make electro music sound wonderfully energic and alive. Can't say that we feel the bass is apart from the sound spectrum as it can happen with bad tweaked 2 or 3 drivers iem, this is a somewhat dry bass that do not crave in the extreme low, there still sub bass but not a airy envelopping one, more a whole low freq presentation without lot of decay. It is fast and precise without feeling synthetic and have good texture to it. With this type of bass presentation we have a U sound signature instead of a V one, wich mean the vocals and mids are clear and more present, this make the Pro HD quite versatile for most music genre. Compared to the PMV soundstage is smaller and bass is more integrated to music, and more powerfull too, a little less precise due to the immense soudstage and very precise instrument separation of the PMV, sound of the Xiaomi is more warm but far from being veiled or not clear. Compared to the Geek audio dual drivers, bass is more foward and articulated, it have better resolution too, but I feel this 2 iem have alot in commun when it come to soundsignature, little more detail with the Pro HD tough. With the Ibasso DX90 these sound superb, and DX90 isn't a bassy music player, so perhaps it will sound much bassy with other type of DAP, with the Benjie S5 it sound weak and veiled, bass struggle to show his face, and this is NOT normal, so the Xiaomi Mi Pro HD need proper amping with there 32ohm impendance, not a amp, just a DAP that can give a little push, Xduoo X3 is small and do well with it as well as any smartphone, but little player like sansa or Ruizu will not be able to push the 3 drivers so it come alive for real.
    Mids (vocal):
    Clear, present, central and textured medium frequencies we got here, with a good sens of realism, perhaps it lack a little warmnest to it to make them more envelopping, but the resolution of whole sound spectrum would have been quite different. Vocal are not the kind you struggle to understand the lyric of a signer, far from it, cause of the good resolution it mix well with rest of instrumental and make the listening experience very sparkling and dynamic. It have good decay to vocal too, especially if you listen to folk or signer songwriter, for pop with big bass big beat etc it will be hard to discern the air between instruments even if the sound is not congested. I feel all frequencies are quite fowards with the HD pro, instruments separation is good but not with alot of space between them cause the soundstage is average, another time, don't take it wrong, it is not tiny sounding iem, more like listening in front row of a show than being in the middle of the band while they play. Compared to the 80$ PMV the vocal feel more gentle and pleasing, less harsh and peircing and do not create ''hissss'', PMV aren't very good with vocal even if they are agressively fowards, but they are more vast presented, due another time to the big soundstage, anyway, it hurt my ears right now so....compared to the Geek audio Hybrid the Xiaomi win another time, vocal are more precise with them and do not feel far away from you like with the Geek, it is less warm too, and make them very impressive due to the fact that the highs are very delicious too!
    Highs (details):
    Oh! I love details, cause as a human I always dream to have bat ears, this earphones are more like cat ears tough, cause they do not feel caricatural or too harsh sounding even if we go PLENTY of details and sparkling highs. The Xiaomi are impatient to show what they got, it will show the whole package at once, texture, micro details, different layers being discernable if you concetrate, all this in a clear but very fowards manner. Low, mids and highs live togheter in harmony, dancing togheter instead of all in there specific corner, this mean instruments separation are not chirurgical but very musical. This type of iem give you the wow effect when you listen to complex music that have plenty of layers and details, it do not became overwhelmingly intense tough and for untrained ears will not be a shock treatment. The only negative side is what I repeat from the beginning: size of soundstage make them feel more fowards than envelopping, but still are immersive, and very easy to listen to, wich is not the case with the PMV A01, even if the soundstage is big and instruments separation very precise, it feel too agressive and harsh sounding some time, The Xiaomi are full of details retreival without being too sharp, layers are well separated but the sound experience is not psychadelic and will not distract you that much.
    Oh my lord, my lord XIAOMI!
    How can you have create such serious hifi iem at a toy price is just nonsensical....and unfair for any competitor. Is it the new era of ultra cheap 3 drivers hybrid earphone when 1 year ago we were super excited about dual dynamic that sound dull? I don't know, so, headfiers, don't be afraid and buy this iem for your collection or just as your unique all in one iem if you are on tigh budget. That with a Xduoo X2 or X3 and your in heaven! This 3 drivers iem are a must have just because of the absurd price, and exquisite sound experience and unique sound signature. With the mic and remote control, it make it a very usefull tool too.Personally, from the 40 pairs of IEM I try, this is the absolute best sound you can get under 50$ because it is versatile and detailed and got bass, if the soundstage was a little bigger and instrument separation more airy, well, we will talk about near perfection....Try them, this is a little investment for the big fun it give!
    I buy them from Gearbest at a flash sale that is still going one...but not for long, after this it will be at a still absurd 28$ I think, check it out!

    "Excellent budget triple driver"
    Pros - Good build quality, volume/ remote controller, V shaped at its best, most affordable triple driver as for now,
    Cons - No flexible strain relief on housing, ear tip not usable for me,
    Xiaomi released their first hybrid about 1 years ago. They are extremely cheap but most reviews said that sound quality is not the strong point for the 1st gen Mi hybrid. Then Mi Hybrid pro released late last year with just slight increase in price. Of course I am interested but the arrival of ultra excellent Onkyo E700M has keep me engaged and entertained well until I decided to purchase this Mi hybrid pro from Gearbest on 6/1/2016. It arrived yesterday and I immediately put it in burn in station. It has more than 30 hours of burn in period up until now.The box contained Mi hybrid pro itself with 4 set of black silicone tip and one cloth case with 1 more brand printed. The box said it was manufactured by 1more division. Unfortunately all the ear tip are too small for my ear and has to resolve with my trusty Spinfit L size.

    The housing, remote and straight earphone jack are made of metal except for the black nozzle on housing which is plastic. The nozzle are angled so it is easy to recognise left and right side housing just by feeling. There is black coloured metal coming down from housing before the real cord come out. They are hard and rigid so it is really not a proper strain relief. Fortunately on earphone jack there is a real flexible plastic as a strain relief. Remote located on right cord. It has proper volume up and volume down button which worked well with my Lenovo A397i. Centre remote is fully functioning for music play/pause and double click to skip/forward song. Not tested yet for mic function. Cable/cord is a black rubbery plastic, not really prone to tangle. But since it was made by 1more I actually hope that its cable has fabric coating like my 1more voice of China. Generally the build quality is good but not top notch like 1more voice of China or even Rock Zircon.
    With competitions; Onkyo E700M and Audio-technica CKB50.

    Well I don't have high hope on this Mi hybrid pro when it come to sound quality. Generally it is a V shaped sound with extra emphasise on treble. Out of the box it has a very high pitch shrilling sound with boomy bass. So definitely need a burn in to get the most out of it. I just put on my usual Spotify playlist and keep on playing up until it has more than 30 hours burn in period. Does it sound better? Yes. But the treble is still very bright and splashing with noticeable colouration and some sibilance. Bass amount about 7/10, and not as impactful as I wish. Vocal as expected is not prominent as compared to bass and treble but still quite clear. Details and instruments separations is below average so background voice and background/additional sound are still heard as distance sound. In general Mi hybrid pro has a V shaped sound with over emphasise on teble and fast but not impactful bass. Fun sound but not as aggressive as I prefer especially when listening to my metal, hard rock music.

    Comparison to Audio-technica CKB50 ;
    Not comparable. CKB50 is a bass oriented single balanced armature driver. Mi hybrid pro is clearly a better sounding earphone especially on treble and bass area. However CKB50 has better vocal and details. Not to mention it is more comfortable and lighter.

    Comparison to Onkyo E700M ;
    Triple driver vs single driver; easy win for Mi Hybrid pro? Not at all. Single driver Onkyo E700M has more balanced sound. Treble are controlled well with no sibilance and bass is more impactful. Voice and details are clear too. But generally the overall sound quality of Mi hybrid pro is not that far behind.

    This is stil one of the cheapest triple driver out there. Some other competitor is Senfer DT2 plus (2 BA+ DD) vs 2 DD + 1BA in Mi hybrid pro. The sound quality is excellent for something that cost 25USD. Next one probably want to buy the much hyped Urbanfun hybrid as comparison. Not recommended for everyone since many people will find that the treble and sibilance are not bearable to their ear. Me? I have to confess that I am more of treble head than bass head, so I prefer treble oriented earphones like Audio-technica CKX9, LZ Z03A, UiiSii HM7 etc. All come down to our own preference, otherwise just get more balanced sound like Rock Zircon or Onkyo E700M.

    "Great budget in-ear earphones with remote"
    Pros - Crisp & clear sound with polite bass, Decent soundstage, Excellent build quality, Comfortable for long hour wear, Nice accessories
    Cons - Average isolation, Microphonic (when worn down)
    Author's Note: The original review can be found at my blog - Mi In-Ear Headphones Pro HD Review @ JayceOoi.com

    Xiaomi Piston 2 earphones is the one that bring me into audiophile world. It is well known for great sound yet value in price. I am so lucky to have their latest Mi In-Ear Headphones Pro HD (Gen 5) from GearBest. This hybrid earphones is loaded with dual dynamic + balanced armature drivers. Does it still packed with best performance from within? Let’s find out…

    - Dual dynamic + balanced armature drivers
    - All-new design. Sounds good, looks good
    - Full metal wired control
    - Stretchable matte wiring
    - Soft and comfortable ear buds

    Well protected

    Package Content
    Mi In-Ear Headphones Pro HD comes with a nice package and well protected in a hard plastic case. Once opened, you can find pouch that can keep Pro HD with rubberize holder. There are extra 3 pair of ear tips (XS, S & L) and user manual in the package too. That’s almost everything that you need to get started and carry it around easily.

    Package contents

    - Weight: 17g
    - Wired control: Available
    - Cable length: 1.25m
    - Jack type: 3.5mm
    - Rated power: 5mW
    - Speaker Impedance: 32 Ω
    - Sensitivity: 98 dB
    - Frequency response range: 20 – 40,000 Hz

    Design & Build Quality
    Mi In-Ear Headphones Pro HD’s build quality is great with CNC diamond cut finished aluminium and solid plastic (for black part) as housing. Same apply to the metal wired control. Furthermore, it also comes with the highly stretchable TPE wiring that is hardy and durable. The 45° angled in-ear design fits snugly when worn cable down method. Can’t be worn over the ear unless you swap left and right channels by the way. There is marking to determine L/R channel on the inner plastic housing but I always use wired control with mic to locate right channel. And 2 vent holes on each earphone housing. As usual, just refer to the photos to know more about its outlook.

    Fit, Comfort & Isolation
    Mi In-Ear Headphones Pro HD fits well thanks to small and lightweight housing. And won’t fell off even not wearing over the ear style. Yes, it is pleasant to wear for long hours (much better and comfort than Piston 2.0). As for isolation, average is what I can say. The bundled ear tips do not give the best seal here by the way (at least for me). You can always change and use 3rd party ear tips. For my case, SpinFit Ear Tip does a better job here.

    4 pair of ear-tips to choose

    Performance Result
    Let’s talk phone call audio quality first. Mi In-Ear Headphones Pro HD performs well in this department thanks to closer to mouth wired remote design. Yup, others can hear my voice loud and clear. And I can hear others’ voice clearly too. As for wired remote, everything is working properly on Android devices – volume control, play, pause and next / previous track all are working great. However, iOS devices like iPhone, iPad and iPod are limited to play/back button only. Volume control is not working here. Do take note…

    with Lotoo PAW 5000

    For me, Mi Hybrid Pro HD has bright sound signature. Totally different from the last earphone that I had review. In short, it is focusing more on treble than bass here unlike the Piston 2.0 V-shape sound which emphasize both bass and treble. By the way, it is easy to drive with 32 Ohm impedance. No need external amp to get the full potential out of it. And will performs just fine on your smartphone and tablet for MP3, YouTube MV, games and movies. And of course, it surely sound better on dedicated DAP like Lotoo PAW 5000 and Zorloo ZuperDAC USB DAC with those high resolution FLAC.

    Overall, crisp and bright is what you will get from highs. You might feel some Harshness on certain track (but not much for me). Mids perform well. Vocals are on the brighter side too. Bass is there but on polite way. As for soundstage, it is decent (much wider than Piston 2.0) and instruments placement separation is clear thanks to that. And that’s make Hybrid Pro HD a very nice earphones to own at this price point. Bigger soundstage is always a plus as it makes everything sound better.

    - Crisp & clear sound with polite bass
    - Decent soundstage
    - Excellent build quality
    - Comfortable for long hour wear
    - Nice accessories

    - Average isolation
    - Microphonic (when worn down)

    Love bright and clear sound earphones? Give Xiaomi Hybrid Pro HD a try. You will like it as I do. With price around US$25, you can’t go wrong with it. As usual, more information can be found at Xiaomi Website. And get yours at GearBest like I did. Enjoy…

    P/S – I checked with my wife who is using Piston 2.0 right now. She is happy that Hybrid Pro HD is much clearer and she love it. And this Hybrid Pro HD will belong to her from now on…

    "A Hybrid Triple-Driver In-Ear for less than 30 Bucks? Yes, it is!"
    Pros - probably as cheap as a triple-driver hybrid IEM can be, good build quality, price-performance-ratio
    Cons - strong v-shape not for everybody, good sound only with deeper insertion, doesn't reach the SQ of most higher-priced in-ears (not much surprisingly)


    Not too long ago, I received a mysterious package I really didn’t expect – inside was the Xiaomi Hybrid Pro HD, a hybrid in-ear with three drivers per side for less than $30.
    I then remembered that George from GearBest asked me, also not long ago, whether I was interested in this in-ear or not, but when I replied with “yes”, I didn’t know that he meant for review and that I would receive it – so here we go now, with a very inexpensive hybrid in-ear with two dynamic drivers and one Balanced Armature driver per side.
    Is it worth being listened to as an inexpensive model for people on a budget? This review that I try to keep short and snappy should answer this question.

    Disclaimer: Quite obviously, I received this in-ear free of charge. Just as always, it will feature nothing less than my honest opinion without any bias.

    Technical Specifications:

    Price: $26.99 (http://www.gearbest.com/earbud-headphones/pp_566702.html)
    Drivers: 2x dynamic, 1x BA (per side)
    Frequency Response: 20 Hz – 40 kHz
    Impedance: 32 Ohms
    Sensitivity: 98 dB SPL @ 1 kHz

    About Hybrid In-Ears:

    As you can read from the technical specifications and mentioned multiple times in the preamble, the Xiaomi Hybrid Pro HD is a little different from most In-Ears and doesn’t only use dynamic or Balanced Armature transducers, but combines both in one shell.

    Most In-Ears use dynamic transducers for audio playback which have the advantage of covering the whole audible spectrum and achieving a strong bass emphasis without much effort. Valuable dynamic drivers are often said to have a more bodied and musical bass that has a more soft impact and decay and lacks of the analytical character that BA transducers are known for. On the downside, in contrast to headphones with other driver principles, dynamic transducers often have a lower resolution.

    Higher-priced and professional IEMs mostly use Balanced Armature transducers, which usually have got a higher resolution than dynamic drivers, are faster, more precise and have got the better high-level stability, which is important for stage musicians that often require higher than average listening levels. On the downside, it is quite hard to cover the whole audible spectrum with just a single BA transducer and strongly emphasised bass is only possible with multiple or big drivers. Some people also find In-Ears with BA transducers to sound too analytical, clinical or cold (in several active years in a German audio community where I wrote multiple reviews, gave dozens of purchase advice and help, from time to time I heard people that got into BA earphones for the first time using these attributes for describing BA earphones, especially their lower frequencies).

    Hybrid IEMs unite the positive aspects of both driver principles and use one dynamic transducer for lows reproduction and at least one BA driver for covering mids and highs, wherefore the often as “musical” described bass character remains and the BA transducers add resolution and precision to the mids and highs – and that’s what the Hybrid Pro HD does with its technology. It is addressed to those people who perceive the clinically-fast character of BA transducers as unnatural, but want to keep the mids’ and highs’ resolution, speed and precision.

    Delivery Content:

    Despite the low price, one gets a full retail package , four pairs of differently sized silicone tips, some paper stuff, a soft carrying pouch and of course the in-ears themselves.

    IMG_2354.jpg   IMG_2355.jpg

    Looks, Feels, Build Quality:

    The in-ears are made of CNC-milled aluminium that looks and feels premium. The inner-facing side is made of plastic for a better heat distribution on colder days.
    The cable is made of normal rubber and while it is a little springy, it appears sturdy, features a three-button in-line remote control and is really flexible. Though, it lacks a chin-slider and the strain relief could be better on some transitions.

    IMG_2356.jpg   IMG_2359.jpg
    IMG_2360.jpg   IMG_2364.jpg

    Comfort, Isolation:

    Depending on how the in-ears are inserted (you can read more about this just in a moment in the “Tonality” section of this review), microphonics can be either on the stronger side or almost non-existent. Comfort is quite good.

    Isolation is somewhat more on the lower side of average.


    My main sources for listening were the iBasso DX80 and HiFime 9018d.

    The largest included silicone tips were used for listening and testing.


    Before I talk about the effect of the insertion depth with this in-ear, let’s take a look at how the front vent on the inner-facing black part of the housings highly affects the amount of bass one is hearing, along with the upper mids, with both parameters increasing the more the vent is blocked/closed:
    This is what I recorded with my pseudo-diffuse-field-compensated-calibrated Vibro Veritas coupler at normal insertion depth (you can read more about the graphs and process of how they are taken and the inaccuracy in my measurements following this external link: frequency-response.blogspot.com/p/about-measurement-graphs.html):

    As you can see, the amount of bass is drastically higher with a closed vent, which is also the case when I have the in-ears inserted in my ears, so if you find the sound-bass-light (caused by insufficient vent coverage by your ear anatomy) or are a basshead, a simple tape mod of the vent will bring the bass forward by a huge margin.

    - - - - - - - - -

    Some in-ears react stronger to insertion depth differences than others – the Hybrid Pro HD is one of them. In my opinion, a somewhat deeper insertion works best for the most coherent and harmonious sound, however it is somewhat difficult to achieve this due to the shape of the in-ears.
    One way to still do it is to switch the sides and to wear the in-ears inserted twisted by 180° with the cables around the ears, whereas the other is to go without switching the sides but to also insert the in-ears twisted by 180°, which is however likely not comfortable at all.
    Less deeply inserted, the treble will sound sizzle-y, artificial, not as coherent and tend to display harshness at higher volumes.
    So this is the sound I am hearing with the ear pieces swapped and twisted by 180°, which I highly recommend to do:

    The Hybrid Pro HD’s tonality is a very consumer-friendly, strong u-shape that tends to being w-shaped with an enhanced bass, strong upper treble and some emphasis on the upper midrange.
    The amount of bass does definitely reach basshead-levels – around really strong 17 dB of an emphasis in the lower midbass and sub-bass compared to a diffuse-field flat in-ear are what I hear when taming the lows to elaborate how much their quantity is in my ears. Quite interestingly though, the bass doesn’t overshadow the midrange, doesn’t spill into it and only makes low vocals gain some body without becoming muddy. Using sine sweeps, I hear it as beginning around 600 Hz, then climbing all the way down to 40 Hz where its climax is that stays upright to 25 Hz and then loses quantity until 20 Hz (which is only really audible with sine sweeps). That its climax is reached so low is also the reason why it doesn’t overshadow the mids – so the bottom-end is strong, with a heavy bass and weighty root, but without spilling in the mids by much.

    From 1 to 10 kHz, I hear the upper midrange/treble gradually increasing, with a moderate dip around 3 and 4 kHz, and a quite strong peak at 14 kHz with great extension above. This makes vocals shift to the somewhat brighter side/favours female vocals more.
    So with the deeper insertion, there are no sudden peaks (excluding the one at 14 kHz), unlike with regular insertion depth where the treble is metallic, uneven and where the sound doesn’t appear coherent.

    It is quite obvious that this kind of tonality is meant for pure fun and people who love a strongly v-shaped sound. And while I mainly prefer a neutral sound, especially at home, I can definitely say that I find the Hybrid Pro HD’s tuning to be very interesting and to deliver boat loads of fun – so yeah, on the subjective level, I also quite like its tuning for a consumer-friendly sounding.

    IMG_2358.jpg   IMG_2363.jpg


    My first impression before I discovered what difference the deeper insertion makes, I heard the sound as being not coherent at all and very peaky and quite harsh – luckily I then played around with the fit a bit, which made the in-ear sound quite noticeably different.

    The sound will definitely not be as coherent as out of a good single-driver in-ear, nonetheless I find it to be quite coherent and also more coherent than with 1More’s E1001.
    The transition between the different driver principles is definitely not strongly noticeable, but it is there.

    The bass remains surprisingly controlled despite the emphasis – it is more on the softer side but not yet boomy or muddy, while it softens up more towards the sub-bass where it can sound a bit loose with energetic tracks.

    The amount of details in the midrange and treble is not necessarily really better than with a good single-driver in-ear in the same price bucket, however it is different here in the mids and treble in terms of presentation, as it appears to sound nimbler and quicker in the highs that however still tend to be a little edgy in their attack even with deeper insertion.

    Overall, I would say that the performance is really solid to good for the price and presumably the best that can be achieved with a well-built in-ear with a multi-driver design for less than $30.

    IMG_2361.jpg   IMG_2362.jpg


    The Xiaomi presents a soundstage that has got around average width with about the same amount of spatial depth and height, which makes it sound quite three-dimensional and spherical.
    With quicker and more energetic tracks, the soundstage remains surprisingly consistent and doesn’t collapse too much.
    Separation is average to good – as good as one could expect at the price anyway, and better in the higher than the lower frequency ranges.


    In Comparison with other In-Ears:
    Xiaomi Piston Colorful Starter Edition:
    The Hybrid Pro HD has got more bass quantity, whereas the Piston has got the less bright midrange and the less bright treble that is however also on the brighter side.
    The Hybrid Pro HD has got the punchier and quicker, better controlled bass whereas I consider both as being equally detailed in the midrange whereas the Hybrid Pro HD has got some advantage in the treble again.
    The Hybrid Pro HD’s soundstage is larger in both directions and features the somewhat more precise instrument separation.

    Fidue A65:
    The Fidue has got considerably less bass, the more present and less bright midrange and the smoother, darker treble.
    The Fidue’s bass is tighter and better controlled, with better definition, and the A65 has also got the superior midrange detail whereas the Xiaomi’s treble is better separated.
    The Fidue’s soundstage is smaller but more precise to my ears.

    AAW Nebula 2:
    The Nebula 2 has got somewhat less overall bass quantity (it is however not that much less), the less bright upper mids and a less bright upper treble that is however also on the emphasised side. While the Nebula 2 does also have a really strong bass along with a somewhat elevated upper treble, it definitely appears more realistic overall and more balanced.
    The around 5x more expensive AAW has got the quicker and better controlled bass that doesn’t soften towards the sub-bass, and also outputs more details in the lows. Its midrange and treble are considerably more detailed and refined in comparison.
    The Nebula 2’s soundstage is a little wider with comparable depth and shows the cleaner instrument separation when put up against the Xiaomi.


    The Xiaomi Hybrid Pro HD is definitely not perfect – but can one get better sound from a hybrid in-ear at this price point? I rather doubt it. So on a budget and with a preference for a strongly v-shaped sound, the Hybrid Pro HD can definitely be considered as an interesting model, however it only sounds coherent and non-metallic in the treble with a somewhat deeper insertion, which might be difficult to achieve.
