I think they sound great... I did the mod and it didn't do much except making them less pretty, maybe I should do burn in

For all that I own, each IEM has a distinct quality that I can pick out, love, and makes me want to return using them.
 
Not the Pistons.
 
At $30 the build quality is a beauty - I can even use the metal clip as a tie bar - but for all my time spent at Head-Fi, build quality and appearance has never been a strong selling point.
 
I was expecting a bass oriented signature that I could live with. The Pistons are also rather V-shaped sounding.
 
Here are my impressions
 

1. bass quantity that bleeds into the mids
2. no bass quality
3. recessed mids (I gave my Sony player a bump in the 0.4 khz, which didn't help much)
4. because the bass bleeds into the mids, the Pistons sound more recessed than they should be
5. poor treble extension
6. uninvolving lacking energy
7. couldn't find that special quality to love

 
In my view, I'm a fairly objective listener. I was surprised they didn't excel with any genre I listened to and, how uninvolving they were in presentation. Overall, I'm disappointed in them. They are in no way Hi-Fi sounding. If joker were to review a pair, I believe he would score them a low 7

The midrange can be bump up by the 1khz and 2.5khz simultaneously. Try that instead of the muddy .4khz.
After trying that please compare to the ba200 for me (as I have those).

What's the difference in sound of 2.0 vs. 2.1? Which one has the better sound and why?

 

[jarrett]

Same thing with different packaging. I shouldn't have said 2.1 actually. I think Xiaomi call them iF Commemorative Edition.

 

[fattycheesebeef]

Pretty V-Shaped to me. I guess Piston would be good for EDM, to me, personally.

The "IF Editions" are the best out of the Pistons money can buy.
 
This is the total bundle package!

 

[HeadHoncho]
