I am currently having skullcandy earphones also which costed around 324 bucks and i'll say they are better than these earphones.
You should consider other option maybe sennihiers they provide good bass than these or philips they are not the player of the market but sure having something better to offer.
Finally Pros:
1.Good cord length.
2.Pretty nice sound isolation.
Cons:-
1.Average Bass(expected more at this rate).
2.Ear buds quality avg.
3.Avg sound( inspite of coming from SONY)
Verdict:-...

dont consider about negative reviews...worth for money ..massive sound quality..superb product by sony...i love it

I ordered this headphone after checking the reviews and I am happy with my decision. The headphone is well-designed and the blue color makes it look funky. Good audio clarity. Pretty decent for a entry level headphone.

Good product. Effective sound cancellation. The bass is not that powerful though, but is handy to use because of it's cord which doesn't get tangled up !!

Decent product , good to hear music but not very good for talking . The mike is not very clear .

Not so good . I used this product for about 10 months and one side of it doesn't work now . Not so durable

Decent product for the price of 430 bucks !! I didn't have any specific requirements like good bass etc while purchasing this, just wanted good audio clarity which was fulfilled...Extra earbuds was an extra advantage...It worked well for one year, however now one earbud is not working..

Looks delicate :(

Good in quality.., audio output is awesome worth buying it.. 'SONY' rocks

I personally have had a good experience with my earlier Sony Headset tooo

Best earphones. Everything about the product is good. Will buy again if required. I bought it 3 times and will buy again. Very comfortable to wear, have used ut continously for 5 hours and never felt like taking them off due to any disscomfort. Sound quality is good, so is the material.

Really nice Headphones. worth of buying it. It's sound is so clear and it doesn't harm even if we hear with full sound..
totally awesome product from SONY..
