Audio T Verdict
The Sony MDR-EX110AP are straightforward wired earphones for listeners who want something compact, lightweight and ready to use without Bluetooth pairing or battery charging. Connect them to a compatible four-conductor stereo mini socket and they can handle both music and smartphone calls.
The 9mm dynamic drivers use neodymium magnets and cover a specified frequency range of 5Hz to 24kHz. With 16-ohm impedance and 103dB/mW sensitivity, they are designed for use with everyday portable sources rather than requiring a separate headphone amplifier.
An inline remote microphone adds useful smartphone functionality, while three sizes of supplied ear tip help achieve a secure fit. At just 3g, with a tangle-resistant 1.2m cable and cord adjuster, the MDR-EX110AP are an uncomplicated and highly portable everyday option.

Sony MDR-EX110AP Wired In-Ear Headphones with Microphone
The Sony MDR-EX110AP 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. 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-shaped 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-EX110AP earpiece contains a 9mm dynamic driver.
The compact driver dimensions help keep the housings small and light, while Sony uses neodymium magnets within the driver system.
Sony describes the MDR-EX110AP as providing crisp and clear music. The final sound will also depend on the ear-tip fit, recording quality, listening volume and connected source.
5Hz to 24kHz Frequency Response
Sony specifies a frequency response extending from 5Hz to 24kHz.
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 headphones 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-EX110AP use a closed in-ear construction, with the 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 earphones do not include active noise cancellation. Any reduction in external 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 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-EX110AP 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 the cord adjuster can be useful for keeping excess cable under control.
Inline Remote Microphone
The MDR-EX110AP 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-EX110AP 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 standard stereo headphone output can provide music playback without necessarily supporting the inline microphone. Full headset operation requires a compatible four-conductor socket or a suitable adaptor.
Compatible Four-Conductor Stereo Mini 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-EX110AP 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-EX110AP 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 plug is connected, music playback may work while the inline microphone remains unavailable.
1.2m Y-Shaped Cable
The fixed cable measures approximately 1.2m and separates into individual left and right sections in a Y-shaped 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 careful storage and use of the supplied cord adjuster 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.
Cord Adjuster Included
The supplied cord adjuster can help gather excess cable during storage or manage slack during use.
Reducing loose cable can help limit unwanted movement and decrease the chance of the cable catching on clothing or nearby objects.
No Battery or Charging Required
The MDR-EX110AP 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-EX110AP 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.
103dB/mW Sensitivity
The specified sensitivity is 103dB/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.
No Specified Water Resistance
Sony does not specify a water-resistance rating for the MDR-EX110AP.
They should be protected from rain, splashes, excessive sweat and other moisture, particularly around the plug, inline remote and microphone.
