My headphones are different according to the difference is pretty extreme, what makes you feel really bad, now I use inexpensive 2 earphones ausm Saturn who liked better.
earphones slip getting out of the ear, unless you rams until it stops purely what may be relatively painful but to original definitely is not it.
Conclusion: The product is only under very unpleasant circumstances usable and more than for single short-term recommended for use, who intends to use it should more hours to buy another product.
I would not buy again, 2 of 5 stars.
