In November 2015 Mi announced a new flagship headphone the Xiaomi Hybrid IEM (As this product is not officially available in the global market, there is no official english name. The chinese name is "小米圈铁耳机" which would translate to Xiaomi Hybrid IEM). The aim of the thread is to provide information and news about new Pistons. The newest update of the xiaomi headphone have a whole new design (again), and now feature a full CNC milled casing. The drivers have also been completely changed (details below)Full chinese descriptions of the new hybrids are available here: http://www.mi.com/quantie As this product is not officially available in the global market, there is no official english name. The chinese name is "小米圈铁耳机" which would translate to Xiaomi Hybrid IEM.The Xiaomi Pistons 2.0 made quite a big splash in the community by providing affordable head phones at a reasonable price. They followed up with the Pistons 3.0 in March 2015, which featured an all new design. The IEMs were well received and received some pretty good reviews ( check out the Pistons 3.0 Thread ).Hybrid IEM (Klippel Drivers) - Released on 11th Nov 2015Pistons 3.0 (Spiral Drivers) - Release in March 2015, these pistons are only available in the black version.Pistons 2.1 & 2.0 (Beryllium Drivers)- This version of the pistons gained a high regard on Head-Fi for their budget price and their stand out sound quality. Check out this Head-Fi thread on these pistons for more informationThese hybrids feature 1+1 hybrid drivers (balanced armature driver and dynamic driver).Diagram Correction (Thanks ForgottenSpy ) these are the correct translations for the two drivers.动圈 - dynamic driver动铁 - balanced armature driverYou can read more about hybrid drivers in the following thread " http://www.head-fi.org/t/615857/the-hybrid-iem-thread-the-best-of-both-worlds " by gnarlsagan . It seems pretty amazing how Xiaomi managed to produce a hybrid IEM and sell in the 16 USD price range instead of 199 USD.Sadly this time Xiaomi did not provide any frequency response curves. What they did promise is that these IEMs have been "professionally tuned" by Luca Bignardi - however without a full frequency response curve this is more or less fluff.The IEMs themselves have a CNC milled metal casing. Pistons 3.0 had a plastic casing which made it feel slightly cheaper and less premium.Remote Control- The remote supports android systems and has partial support for iOS. On android all 3 buttons work and can control the volume. On iOS only the middle Stop/ play button works (tested on iphone 6).The remote is positioned on the cable for the right earphone, around 2 inches below the earphone itself.Official retail pricing (Mi.com) is at 99 RMB (~), which is the same price as all the previous Pistons.I'll post links of international resellers after they are verified.**Note: Due to shill marketers, forum admins have warned new members not to post links to resellers**Source: FLAC, mp3, Tidal.

Equipment PC - Aune T1 DAC, Samsung S4Burn in time:Comfort: In terms of comfort, These IEMs are an iterative improvement on already quite comfortable spiral design of Piston 3.0. As you can see from the following image, the angle of the nozzle has been slightly adjusted to improve comfort – otherwise everything else is unchanged. The earpiece is is made out of CNC milled metal, hence making it feel much more expensive.When I first put on the new hybrid IEMs I was pleasantly surprised by the amount of bass it provided. The bass was distinct and more rich than that of the Pistons 2.0 – in comparison it sounds less muffled and more detailed. The bass is definitely not overpowering and is nowhere near bass-head level. I found trance music most enjoyable with these IEMs, and spent more time listening to Infected Mushroom / AC/DC then I usually do. I would like to note with more chill/acoustic music I found that there was a bit too much bass leading to rhythm guitars / drum beats being more pronounced - () Luckily the emphasis on bass fades with after an 20 hour burn in. In fact after the burn in, I can no longer hear the overemphasis on bass.The Mids are clear and have good separation (Esp after burn-in). They are definitely a step up from Pistons 2.0 (Could clearly hear the huskiness of Bryan Adams) but nowhere as detailed as 3.0. If you are used to listening to more balanced IEMs like the Vsonic GR07 (I know this is much more expensive), then you will definitely feel that something is missing. This is not surprising as this is a 1+1 hybrid and not a 1+2.Vocals are clear and crisp – one of the benefits of having an armature driver. Both female and male vocals sound great. Cymbals are clear. Nothing too special here.: In terms of sound signature, Xiaomi is definitely looking to improve upon the V-shaped legacy of Pistons 2.0. The hybrid drivers bring a lot to the table, and definitely give a sound that’s usually only found a much more expensive IEMs.Edit: Changed the naming of these from Pistons 4.0 to Hybrid IEMs following a correction from thatBeatsguy Edit: Updated review to account after extensive burn in time
