Audio T Verdict
The Sony MDR-EX15AP are uncomplicated wired earphones for listeners who want something small, light and ready to use without Bluetooth pairing or battery charging. Connect them to a compatible four-conductor headset socket and they can handle both music and smartphone calls.
The 9mm dynamic drivers use neodymium magnets and lightweight PET diaphragms, covering a specified frequency range of 8Hz to 22kHz. With 16-ohm impedance and 100dB/mW sensitivity, they are designed for everyday portable sources rather than requiring a separate headphone amplifier.
An inline remote microphone adds useful smartphone functionality, while three sizes of supplied silicone ear tip help achieve a secure fit. At approximately 3g, with a tangle-resistant 1.2m cable and a choice of four colours, the MDR-EX15AP are a practical everyday option.
This Is the MDR-EX15AP with Microphone
This page is for the Sony MDR-EX15AP with a four-conductor plug and inline smartphone remote microphone. It is not the standard MDR-EX15LP, which uses a conventional stereo mini plug and does not include the microphone connection.
Sony MDR-EX15AP Wired In-Ear Headphones with Microphone
The Sony MDR-EX15AP are compact wired in-ear headphones designed for music, podcasts, calls and everyday portable listening.
Each earpiece contains a 9mm dynamic driver using a neodymium magnet and PET diaphragm. The closed in-ear design is supplied with Small, Medium and Large ear tips to help provide a secure and comfortable fit.
A fixed 1.2m Y-type cable terminates in a gold-plated L-shaped four-conductor stereo mini plug. An inline remote microphone provides compatible smartphone call and playback functionality.

9mm Dynamic Drivers
Each MDR-EX15AP earpiece contains a 9mm dynamic driver using a neodymium magnet.
Sony describes the driver system as producing powerful, balanced sound while allowing the earpieces to remain compact and lightweight.
The final sound will also depend on the ear-tip fit, recording quality, listening volume and connected source.
PET Driver Diaphragms
The MDR-EX15AP use PET diaphragms within their dynamic driver assemblies.
The diaphragm is the part of the driver that moves to create sound. Its size, material, suspension and relationship with the magnet all contribute to the overall performance.
A driver material should not be judged in isolation, as the complete acoustic design determines how the earphones perform.
8Hz to 22kHz Frequency Response
Sony specifies a frequency response extending from 8Hz to 22kHz.
A quoted frequency range describes the stated operating bandwidth of the driver system, but does not by itself explain the overall tonal balance or how the earphones will sound to an individual listener.
Fit is especially important with in-ear headphones because an incomplete seal can reduce bass response and alter the perceived balance.
Closed In-Ear Design
The MDR-EX15AP use a closed in-ear construction, with the silicone ear tips sitting inside the entrance of the ear canal.
A suitable seal can help provide:
- More consistent bass response
- Greater stability during movement
- Useful passive separation from surrounding sound
- A more secure and comfortable fit
The MDR-EX15AP do not include active noise cancellation. Any reduction in surrounding sound comes from the physical fit of the earpieces and ear tips.
Small, Medium and Large Ear Tips
Sony supplies pairs of Small, Medium and Large silicone ear tips.
The most suitable size should create a secure acoustic seal without producing uncomfortable pressure. A loose fit can reduce bass and allow the earpieces to move, while a tip that is too large may become uncomfortable.
Check Both Ears Independently
It is normal to need a different ear-tip size in each ear. Choose the combination that provides the most secure and comfortable fit rather than assuming both sides must use the same size.
Approximately 3g Weight
Sony specifies a weight of approximately 3g.
The lightweight earpieces make the MDR-EX15AP easy to carry and reduce the amount of weight supported by the ears during use.
The fixed cable and inline remote add some additional hanging weight, so routing the cable carefully can improve comfort and reduce unnecessary movement.
Inline Remote Microphone
The MDR-EX15AP incorporate an inline remote microphone for use with compatible smartphones and other devices offering a suitable four-conductor headset connection.
The microphone supports compatible voice calls without requiring the phone to be held directly in front of the listener.
Remote operation can vary according to the connected device, operating system and application. Functions not supported through the inline remote can be controlled from the source itself.
Smartphone Call Compatibility
The four-conductor stereo mini plug carries separate connections for stereo audio and a compatible microphone signal.
This allows the MDR-EX15AP to operate as a headset with compatible phones, tablets, laptops, computers and games controllers.
Compatibility should be checked where the source uses an unusual headset wiring arrangement or separate headphone and microphone sockets.
Not Every Headphone Socket Supports a Microphone
A conventional stereo headphone output can provide music playback without necessarily supporting the inline microphone. Full headset operation requires a compatible four-conductor socket or suitable adaptor.
Gold-Plated Four-Conductor Plug
The cable terminates in a gold-plated L-shaped four-conductor stereo mini plug.
The right-angled design allows the connector to sit closer to the body of a compatible phone, tablet or portable player than a long straight plug.
Gold plating is used on the contact surface to help provide a reliable electrical connection with a compatible socket.
Using the MDR-EX15AP with Modern Phones
The earphones connect directly to compatible devices fitted with a conventional four-conductor stereo mini headset socket.
Many current smartphones no longer include this connection. A suitable USB-C or Lightning audio adaptor may therefore be required.
The adaptor must support both stereo audio and microphone input if the inline microphone is required. Some basic adaptors provide headphone playback without supporting headset controls or microphone operation.
Using the MDR-EX15AP with a Laptop or Computer
The earphones can be used with compatible laptops and computers fitted with a combined headphone and microphone socket.
Computers with separate headphone and microphone sockets may require a suitable headset splitter adaptor for both functions to operate.
If only the headphone connection is available, music playback may work while the inline microphone remains unavailable.
1.2m Y-Type Cable
The fixed cable measures approximately 1.2m and separates into individual left and right sections in a Y-type arrangement.
The length is intended for personal listening where the phone, player, tablet or computer is kept relatively close to the listener.
The cable cannot be detached or replaced independently.
Tangle-Resistant Cable Design
Sony describes the 1.2m cable as tangle resistant, helping make the earphones easier to carry in a pocket or bag.
No conventional cable can be entirely tangle-free, but storing it loosely can reduce knots and unnecessary strain.
Avoid Tight Cable Wrapping
Store the cable in a loose loop rather than wrapping it tightly around a phone or the earpieces. Repeated sharp bends can place unnecessary strain on the internal conductors and plug.
No Battery or Charging Required
The MDR-EX15AP are passive wired earphones and contain no rechargeable headphone battery.
They can be used whenever a compatible headphone connection is available, without waiting for the headphones to charge.
This also makes them useful as a simple backup pair when wireless headphones or earbuds run out of power.
No Bluetooth Pairing
The wired connection avoids Bluetooth pairing, wireless dropouts, codec selection and headphone battery management.
The earphones cannot be used wirelessly and must remain physically connected to the source.
16-Ohm Impedance
Sony specifies an impedance of 16 ohms at 1kHz.
The MDR-EX15AP are intended for use with everyday portable and domestic equipment rather than requiring a dedicated high-powered headphone amplifier.
Available volume will still depend on the output capability of the connected device, any adaptor being used and the level of the recording.
100dB/mW Sensitivity
The specified sensitivity is 100dB/mW.
Sensitivity indicates how efficiently the earphones convert electrical input into sound output. It should be considered alongside impedance and the capabilities of the source.
Protect Your Hearing
Listening at excessive volume can damage hearing. Reduce the source volume before inserting the earphones and increase it only as far as required for comfortable listening.
100mW Power-Handling Capacity
Sony specifies a maximum power-handling capacity of 100mW.
This is an electrical limit rather than a recommended everyday listening level. It should not be treated as a target for amplifier output or volume.
No Specified Water Resistance
Sony does not specify a water-resistance rating for the MDR-EX15AP.
They should be protected from rain, splashes, excessive sweat and other moisture, particularly around the plug, inline remote and microphone.
Black, White, Blue and Pink Finishes
The Sony MDR-EX15AP are available in Black, White, Blue and Pink finishes.
Technical performance remains the same across the different colour options.
