I am in India and want upgrae from my S4. I love my S4 as I bought 6 pairs of in ears from various brands, Senns, Nuforce, creative et all but due to my tiny ear canal none fit. The I bought the S4 nd voila ! I love the bass they produce and the amazingly wide soundstage and crispness. Now im cunfused as to waht to buy, here the Custom are available for 9000 Rs and the X10 for 11000 Rs. What i want to know is, where is the bass better and will comfort be a problem with the customs ?
