you can refer my Xiaomi Piston 2 review as an introduction to this one, because this two are indentical in general. the only difference between they're, is the frequency balance i think. M4 comes with 125-250hz strong bass frequencies amplified on somewhat level. M4 is overall sounds better but as i said, they're pretty much identical with each other.
comparing the M4 to M5, with M4 you'll lose some bass & treble compared but, "Tuned for Vocals" title on yourbrainwavz.com is for real this time (surprisingly). so you'll have good seperated, clear vocals with M4. i also detected some 4khz frequency amplification on the device (but on a modest level, not like R1's 2khz situation). 2-3 desibels of decrement on this frequency will help it's naturality.
in general, i personally favor M4's sound to piston but even with the discounted mp4nation prices, i cannot recommend it over piston due to build quality issues. mine was gone from the first day. mp4nation sent me a microphoned version after that. i sold it but it also reported dead after 3 months. i found a lot of people in the forums who faced the same situation.
but i must say, brainwavz-mp4nation is very good about the warranty support. they have a real, painless warranty service but sound quality is more important and this is where M4 falls down. if you wanna buy a good earphone for the price, keep out from this and alike. there is a lot better models out there, both for the piston and M4-M5.
btw, i was a little "mp4nation beginner" at the time of purchase and i bought it from a reseller and i just can't believe i wiped 45 washingtons for this.
