Sony's MDREX15LP In-Ear Headphones deliver a powerful and balanced audio experience with 9mm neodymium drivers. Designed for both comfort and portability, these lightweight headphones feature secure-fitting hybrid silicone earbuds that come in three sizes (S, M, L) to ensure a personalized fit. The high-energy magnets produce deep bass and clear treble across an 8 Hz–22,000 Hz frequency range. A Y-type cord with a slider is included to prevent tangling, making them ideal for music on the go.
