Sony MH-EX300AP Earbud Headset

The Sony MH-EX300AP is a wired earbud headset with a 3.5 mm L-shaped stereo mini plug. It uses a 13.5 mm dynamic driver with a neodymium magnet rated at 440 kJ/m3. The cable length is 1200 mm (47.2 in) and the headset includes an inline microphone for calls.

Ideal for calls and music on any 3.5 mm device

This headset suits users who want a simple wired connection for smartphones, tablets or computers. It automatically fades music during incoming calls. Buyers who need wireless freedom, active noise cancellation or a USB-C connection should look elsewhere.

13.5 mm driver with 16 ohm impedance

The 13.5 mm dome-type driver delivers a frequency response of 5 to 24,000 Hz at 16 ohms impedance and 105 dB/mW sensitivity. This specification determines the volume level and tonal balance you will hear from portable sources.

Questions about this item

How do I plug in the L-shaped 3.5 mm stereo mini plug and what step do people miss?

Insert the 3.5 mm plug fully into the device jack until it clicks; the L-shaped body should sit flush so the connection stays secure when the cable moves.

Which part of the MH-EX300AP is most likely to need replacement after daily use?

The 1200 mm OFC neck-chain cable and inline microphone module endure the most flexing and are the first items to show wear.

At what volume level does the 16 ohm driver hit its thermal limit during long listening sessions?

Continuous playback near the 105 dB/mW sensitivity rating can overheat the 13.5 mm CCAW voice coil, so keep average levels lower for extended use.
