Sony MDR-EX155AP In-ear Headphones, White

The Sony MDR-EX155AP is a set of wired in-ear headphones designed for music playback and calls on devices with a standard audio port. Audio is delivered through 9 mm dynamic drivers equipped with neodymium magnets, which are engineered for a balanced sound output. These drivers support a frequency response range of 8 Hz to 22,000 Hz, covering both bass and treble tones. The closed acoustic system contributes to passive noise isolation by physically blocking a portion of external ambient sounds.

Functionality is enhanced by an in-line microphone integrated into the 1.2-meter cable, which facilitates hands-free calling. Call management is handled through a single button on the in-line remote, providing a straightforward user interface. With a weight of only 3 grams, the earbuds are constructed for portability and extended use. Their 16-ohm impedance and 103 dB sensitivity rating ensure compatibility and efficient power usage with a wide range of smartphones and portable audio players.
