This is a great earphone from SONY.......I didn't have any problems as some previous users were saying........Sound quality is extremely good with the deep bass......does a good job in isolating external sound/noise.......When wearing these headphones and speaking, one can hear one's sound vibration!!! Clarity of sound is present with great audio frequency range which makes one hear to sound which other cheap headphones can't detect.....

just got them now and you gotta try these earphone they are totally amazing and the best thing is they don't give you pain even after wearing them for long time. the bass is also very good , these earphones are definitely for a music lover

I had purchased this headphone at Sony world paying Rs. 990 some months before. I sparingly used it and after sometime the right side ear bud stopped working. I contacted Sony care and they promptly responded that Sony India doesnt have accessory replacement policy. I had to throw them away paying 1k. The quality of the earphones were good when they worked. But when I googled, I found that right-ear-bud not working is most common problem with this headphone. So avoid buying them.

Its very good compatible with mp3 players and few phones and even with pc. But the problem is it is very delicate. It satisfied me for more than 6 months. After that, right ear stopped working. No repair for it. I had thrown it out now. I don't advice it though it is good in clarity and looks.

The headphone sounds awesome.It has very good deep bass and mid-levels but the highs are not up to the mark.
The jack of the headphone got loosed and only one side of headphone was working just after one month of purchase.I could not believe that after spending 1K rupees i got such poor quality products and that too from Sony.

Even i got the same problem even after purchasing with the price 1K after probably 2months only my left side of the earphone is working and i am wondering what should i do with the one which is working ??

this is the best in every ratio. just go 4 it , without thinking.
i use it from a week its excellent.

this product is excellent performance it has 2222222222222222 much of sound effect i really liked it

On 28th Nov,2014, I ordered this earphones from SONY, model no. : MDR-XB30EX for 1199 INR, and after recieving the product I didnt checked whether I got the actual product or not, as the earphone I recieved looked very same.
But today I realised that they tricked me into a wrong and cheaper product. They gave me the SONY MDR-EX50LP instead, which is way cheaper that the earphone I ordered.
Moreover the product is not working too.

Expected a lot more from you FLIPKART. Stop cheating people.
