Review of Xiaomi In-Ear Piston Pro HD – Launch 11.11


Its November 11th and its time for the launch of another Mi IEM flagship! This year Xiaomi builds on the success of last years Mi Hybrid IEM by offering an more expensive “Pro HD” version, (Yes the product is officially titled “In-Ear Headphones Pro HD“, which is quite a mouthful). The major improvement in this model is the driver – this IEM uses a 2 Dynamic Driver +1 Balanced Armature Hybrid driver instead of a 1+1 Hybrid. This year an additional 50 RMB ( 7 USD) is added to the base price of these IEMs. Whilst it is a bit more expensive, it is the cheapest 2+1 hybrid this year. It is also interesting to note that these IEMs use a two dynamic driver instead of two balanced armatures like other 2+1 hybrids. 

Note: These Pro HD IEMS should not  be confused with “Mi In-Ear Headphones Pro” which were released last year. To make matters more confusing, the IEMs on the chinese website are called “Pro” without the “HD”. 

 In this article I will refer to these as “Pro HD” and last year’s model as “Pro”

 These IEMs pack a new 3 driver hybrid IEM. 


The official website for these IEMs: (Chinese)

Currently no official english webiste


 The Xiaomi Pistons 2.0 made quite a big splash in the community by providing affordable headphones at a reasonable price. They followed up with the Pistons 3.0 in March 2015, which featured an all new design. Xiaomi first launched their hybrid IEM “Mi In-Ear Headphones Pro” in during november 2015. 

Note: The Pro HD headphones comes in a large box which encases the plastic box xiaomi is known for. The back of the box actually has English! which is quite helpful. 

The package includes a carrying case, 3 extra ear tips of different sizes and a plastic holder. 


The IEMs themselves have a CNC milled metal casing.

 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. 

The pro HD edition features a 2 DD+1 BA Hybrid driver. These are upgraded from the 1+1 Hybrid in the previous model. Xiaomi claims These drivers have been rebalanced to feature stronger mids (a weakness in the previous model) along with a stronger bass.
