Soundmagic e10 vs Brainwavs m5 vs Panasonic RP-HJE450 vs Klipsch S4 ,which is the best (sound Quality)

what is better sonudmagic E10 , Brainwavz M5 or Panasonic RP-HJE450  based on sound Quality only  ( prise is not a issue)

I Own Soundmagic E10 I am thinking of upgrade   i have following options    Brainwavz M5 Klipsch s4 Panasonic RP HJE450 Philips SHE9700 or any other   What should i Buy , just suggest by sound quality  only

Cos  IEMs have Comparatively low soundstage than over/On Ears , While Gaming Soundstage Matters a lot

I was just asking for comparison of devices (meizu mx4 pro , vivo x5 max ) with iPhone 6/+ ,As if iPhone 6/+ was Superior to these mobile phone devices  or else   ps you can google these phones models if u want to know

they are far cheep to

Why would i buy iPhone , when we already have hi-fi phones like MX4 Pro & Vivo X5max ,they have far better audio performance than apple's iphone 6
