Design and Features:
The unit comes in a neat and compact package, which includes the earphones, 2 extra earbuds and the literature. There is something new and innovative about the earbuds, and it's in their construction. Sony states that they are made of hybrid silicone, which basically means that the sleeve part of the bud is made of a softer silicone rubber, while the central tube is more rigid, and also color coded, thus providing a firm and comfortable fit. The earphones are available in 3 sizes - small, medium and large - thus most ear canals can be covered. The driver size is 9mm, which is across the board for the EX series. Magnets used are neodymium, which is also a commonality in headphone drivers these days. The neodymium helps in producing more power for lesser mW consumed. We received a black piece but there are a few other color options available. The earphone is black all over, with a glossy coat for the rib joining the cord with the tiny driver enclosure. 'Sony' is neatly etched on this surface, in white.
The impedance is 16 ohms, which is on the lower side, making the earphones apt for low voltage outputs like MP3 players. The rated output for frequency response is 6 Hz - 23000 Hz, which is extremely wide. We will have to run some pure sine tones to check how low it goes. Sensitivity is medium at 100 dB. Judging by this, we should not have a problem with loudness. Plus the fact that these are in-ear, we can expect a decent degree of acoustic noise cancellation. The cord length is 1.2 m which is very sufficient. I feel a minimum length of 1 m is good enough.
