So i just got the Piston 3 for $17, (yay for living where xiaomi sells thing officially).
First Impression, no burning in, out of the box. This thing sounds muffled... I thought it was me, but then i grab my piston 2.1 and i was right how it sounds muffled.
The sound staging is also not as impressive as Piston 2, not as wide (for an IEM, please don't get misdirected, headphone will have better soundstage)
One curious thing is if i press the phone deeper to my ear then the muffled-ness gets better, but i just can't achieved it with the stock tips, not even with some other tips i have.
The mids are definitely less recessed than piston 2 and the high seems to be less rolled off. The bass? I think somehow it is not as defined as piston 2, might as well because of the muffled sound.
The build quality is good, Piston 2 good.
any other who wants to share their experience? would like to know if piston 3 really is less clear than the 2nd generation
I will go and burn the thing down, let's see if anything improve.
