During my trip at japan.
I notice a new earphone just release from Sony, which is Nude MDR-EX90SL.
The good about in tokyo, they have setup all the earphones at the store and allow you to test till you happy.
And this earphone is selling like a hot cake in Tokyo. Many places out of stock.
I managed to buy this Sony MDR-EX90SL at Hibiya and it also a last piece.
Good bass, good mid range. 9980 Yen.
