Of course I have heard them together! The guy sits two feet away from me in the office. I could also post a picture of the phone and the earphones together when I go to office tomorrow.
Then i am really surprised how you cannot figure out the low sound output through 3.5 mm jack using ep630 . Next time check out the sound through both ep630 as well as the stock usb headphones that comes with i450 then you will notice the difference . When i use ep630 with i450 on mumbai locals , the volume is so low that i am barely able to listen properly . By the way i will be posting my i450 review tomorrow since i am no able to find my usb cable of my digicam hence the delay .

I have ordered senn cx-300 from Ebay for which i have to shell out Rs 2450 . I will tell you the result . By the way i have tried senn mx-160 with i450 and the result was good ,also they are not that costly , you can get them for about 450 Rupees .
