The Sony MDR-ZX110AP are wired on-ear headphones designed for mobile use, featuring a closed-back design that helps isolate you from your surroundings. They are powered by 30 mm dynamic drivers that cover a frequency range from 12 Hz to 22,000 Hz, providing a balanced sound with a sensitivity of 98 dB SPL/mW and an impedance of 24 Ohm. Constructed from lightweight ABS plastic, these headphones weigh only 120 g and feature a foldable frame that makes them easy to slip into a bag for travel. A 1.2 m cable connects to your device via a standard 3.5 mm mini-jack, and an integrated in-line microphone with a remote button allows you to handle calls and control playback without reaching for your phone.
