Sony Fontopia MDR-E9LP In-ear Headphones, Grey

The Sony MDR-E9LP are wired in-ear headphones designed for portable audio listening. They incorporate 13.5 mm dynamic drivers with neodymium magnets, which are engineered to reproduce a balanced sound profile with an emphasis on low-frequency bass response. The open acoustic system provides a wide frequency range from 18 Hz to 22,000 Hz. With a sensitivity of 104 dB and an impedance of 32 Ohms, these headphones are compatible with a broad array of standard devices such as smartphones and portable music players without requiring a dedicated amplifier.

Connectivity is established through a standard 3.5 mm plug, attached to a durable 1.2-meter cord that offers sufficient length for typical use. The overall construction is focused on portability and comfort, with the earbuds weighing only 6 grams to minimize fatigue during extended listening periods. To accommodate different ear sizes and ensure a stable fit, the package includes two sets of silicone eartips. This model is built specifically for audio playback and does not integrate an in-line microphone or remote for managing calls or media controls.
