The Sony MDR-EX15LP are lightweight in-ear headphones designed for comfortable daily listening. They feature 9 mm dynamic drivers with high-power neodymium magnets that deliver a wide frequency response from 8 Hz to 22,000 Hz, ensuring a balanced sound across various music genres. Constructed from ABS and silicon, these earphones weigh only 3 g per bud, making them easy to wear for long periods. The 1.2 m Y-type cable includes a cord adjuster to keep the wires tidy and ends in a gold-plated L-shaped 3.5 mm mini-jack for a secure connection. To help you find the right fit and improve noise reduction, the package comes with hybrid silicone rubber earbuds in three different sizes: small, medium, and large.
