Give me few days guys,,,,got my E30 replaced n also got my new R1.
From initial impressions E30 is clear winner as far as Mids n Highs are concerned.
R1 wins in Bass department. It has depth n more capacity to handle boomy songs. E30 has more punchy bass but small nozzle prevents to get proper bass(may b my ears r too big for E30)
Soundstage of E30 feels really tiny after listening to R1.
I'm waiting for both the earphones to burn-in. Will post in depth review later.
