Sony MDR-XB55AP In-ear Headphones, Blue

The Sony MDR-XB55AP is a set of wired in-ear headphones equipped with 12 mm dynamic drivers and neodymium magnets. These components produce audio across a frequency response range of 4 Hz to 24,000 Hz. The closed acoustic design offers passive noise isolation by sealing the ear canal from some ambient sounds. With an impedance of 16 Ω and sensitivity rated at 110 dB, these headphones are engineered for use with smartphones, portable music players, and other devices with a standard audio output.

Connection is made via a 3.5 mm audio plug on a 1.2-meter Litz cable, which is designed to resist tangling. The cable includes an in-line remote and a built-in microphone for managing calls and controlling music playback. The headphones weigh approximately 8 grams, and the package contains multiple sizes of silicone ear tips to facilitate a secure fit for different users. A carrying pouch is also supplied for storage and portability when not in use.
