The Sony MDR-ZX310AP is a simple wired on-ear headphone with an in-line microphone, a 3.5 mm plug and a folding headband. It is worth considering if you want a light, no-battery headset for a phone or laptop with a headphone jack, for music, classes and calls. It is not for anyone who needs wireless freedom, noise cancellation or a USB-C-only phone without an adapter.
This article covers the black variant that the affiliate link below points to (Amazon.in listing title: “Sony ZX Series MDR-ZX310AP Wired Headband Stereo On Ear Headset -Black”). It is based on Sony’s official specification page and the Amazon.in listing data, both checked on 17 October 2026. It is not based on hands-on testing, and we have not measured sound or comfort ourselves.
Short verdict: the ZX310AP is a sensible basic headset if your device still has a 3.5 mm jack and you value plug-and-play simplicity over features. Its on-ear fit and plastic build are the trade-offs you accept at this level.
Quick verdict
- Best for: students, office calls and casual music on phones or laptops with a 3.5 mm jack
- Skip if: your phone has only USB-C and you do not want a dongle, or you want wireless or noise cancellation
- Key strengths: 125 g weight without cord (per Sony), folding design, in-line microphone, no charging needed
- Key limitations: on-ear pads can press on the ears in long sessions, fixed 1.2 m cable, plastic build, no active noise cancellation

What the specs mean in daily use
The 3.5 mm four-conductor plug and the microphone
The listing title calls the ZX310AP a headset, and Sony’s spec page lists a microphone. Sony describes the Sony MDR-ZX310AP as a four-conductor (often called TRRS) gold-plated L-shaped mini plug. That fourth contact is what carries the microphone signal. In practice, it means the headset works as a calling headset on phones and on laptops that have a combined headphone-and-mic jack. Many desktop PCs and older laptops have separate pink (mic) and green (headphone) jacks. On those, the ZX310AP will play audio but the microphone needs a TRRS-to-dual-3.5 mm splitter.
The Amazon.in listing says the control type is “Remote”. Sony’s spec page lists the Sony MDR-ZX310AP but does not detail the controls, so check the product photos on the listing to see what the in-line unit looks like before you rely on particular button functions. How any in-line control behaves also depends on your phone, since some functions vary between Android phones and iPhones.
30 mm drivers and the 10 Hz to 24 kHz range
A 30 mm driver is smaller than the 40 mm drivers common in bigger over-ear headphones. Smaller drivers in an on-ear design are typical for portable models, and the listing’s feature bullets describe the sound as “powerful, balanced”. Treat that as the maker’s description, not a measurement.
The 10 Hz to 24,000 Hz figure looks wide, but frequency range numbers tell you very little about how a headphone actually sounds. Human hearing generally runs to about 20 kHz, and two headphones with identical ranges can sound very different. Seal on the ear, pad material and tuning matter much more. Because this is an on-ear design, bass in particular depends on how firmly the pads sit on your ears, so the result can vary with head size and glasses.
Sensitivity and impedance: will a phone drive it?
An impedance of 24 ohms and a sensitivity of 98 dB/mW mean the ZX310AP is designed for portable devices. Phones, laptops and tablets do not need a separate amplifier to drive it to normal listening levels. The flip side is that low-impedance headphones can pick up background hiss from poorly shielded laptop audio outputs. If you hear a faint hiss on a PC, try a different port or a USB audio adapter.
Weight, folding and comfort
Sony lists the weight as 125 g without the cord. That is light for a headband headphone, and the folding design makes it easy to slip into a bag. On-ear headphones rest on the ear rather than around it. Some people find that comfortable for an hour or two. Others feel pressure, especially with glasses. If you plan to wear a headset for full workdays, an over-ear model may suit you better.
The listing says the Sony MDR-ZX310AP material is plastic, and Sony’s listing bullets mention padded earcups. A plastic headband is normal at this level, but it is worth handling the folding hinges gently rather than forcing them, since hinges are a common wear point on any folding headphone.
Noise isolation, not noise cancellation
The Amazon.in listing describes the noise control as “Sound Isolation”. That means the closed earcups physically reduce some outside sound. There is no electronic noise cancellation. On a bus or metro, you will still hear a lot of the surroundings, and you may be tempted to raise the volume, which is worth avoiding for your hearing.
Listing details that look wrong
Some fields in the Amazon.in technical details do not match Sony’s official information. Rely on Sony’s page where they disagree:
- The listing names the brand as “Sony Music” and gives the model name as “700”. The model number field (MDR-ZX310AP/Black) and the title are the reliable identifiers.
- The listing says “Over Ear” in its ear placement fields while also saying “On Ear” for form factor. Sony describes the ZX310AP as an on-ear headband headphone.
- The listing gives the control method as “Touch”. Sony does not describe touch controls for this model.
- The listing’s box contents field says only “User Manual”. Sony’s page lists operating instructions in the box, and it does not list a detachable cable.
Who should buy it
- Students attending online classes on a phone or laptop with a combined 3.5 mm jack
- Office users who want a cheap, reliable calling headset that never needs charging
- Anyone who wants a light, foldable backup headphone for travel
- People who dislike pairing and battery management
Who should skip it
- Owners of phones with no 3.5 mm jack who do not want to carry a USB-C or Lightning adapter
- Commuters who need active noise cancellation
- Gamers who want a boom microphone or surround features
- Anyone who finds on-ear pressure uncomfortable or wears thick-framed glasses for long hours
Alternatives worth comparing
Each of these trades the ZX310AP’s simplicity for different strengths. Facts are from the official pages or listings checked on the same date.
- Sony WH-CH520: Sony’s wireless on-ear option with a long rated battery life. We have covered it in our Sony WH-CH520 review. Choose it if you want to drop the cable.
- ZEBRONICS Thunder: a wireless over-ear headphone that Zebronics lists with Bluetooth 6.0, 40 mm drivers, a rated 60-hour playback at 50% volume, an AUX input and microSD playback. It is heavier but can also be used wired.
- JBL Tune 780NC: a wireless over-ear headphone with adaptive noise cancelling and multipoint Bluetooth, for people whose main problem is commute noise.

What to check before you order
- Variant: the link below is for the black MDR-ZX310AP. Sony’s spec page covers both the MDR-ZX310 and the ZX310AP and lists red, blue, white and black colours. Confirm “AP” and “Black” in the listing title before you buy.
- Your device’s jack: make sure your phone or laptop has a 3.5 mm combined headset jack. If it only has USB-C, you will need a USB-C to 3.5 mm adapter that supports microphones.
- Desktop PCs: separate mic and headphone ports need a TRRS splitter for the microphone to work.
- Seller: check that the seller is Sony’s authorised seller or Amazon, since the 1-year warranty on the listing depends on a valid invoice.
- Warranty and service: keep the invoice. Check Sony India’s support site for how warranty claims and service work in your city.
- Box contents: expect the headphone and instructions, per Sony’s page. There is no carrying pouch listed.
See the Sony MDR-ZX310AP in Black on Amazon.in and confirm the variant and seller before ordering.
Care tips to make a wired headset last
- Unplug by holding the plug, not by pulling the cable.
- Avoid wrapping the cable tightly around the headband, which stresses the joint where the cord enters the earcup.
- Fold the headphone only along its hinges, and store it where it will not be crushed in a bag.
- Wipe the earpads with a dry or slightly damp cloth, and let them dry before use.
- Keep volume moderate. A rough rule is that if people near you can hear your music, it is too loud.
Frequently asked questions
Does the Sony MDR-ZX310AP have a microphone?
Yes. Sony’s spec page lists a microphone and a four-conductor plug, which carries the mic signal. Sony’s page covers both the MDR-ZX310 and the ZX310AP, so check that your listing says ZX310AP.
Is the MDR-ZX310AP over-ear or on-ear?
It is an on-ear headband headphone according to Sony. The Amazon.in listing mentions “Over Ear” in some fields, but that conflicts with Sony’s description and the listing’s own form factor field.
Will it work with a phone that has no headphone jack?
Only with an adapter. Use a USB-C (or Lightning) to 3.5 mm adapter that supports a microphone if you want to take calls.
Can I use it with a desktop PC for calls?
If the PC has a combined headset jack, yes. If it has separate mic and headphone jacks, you need a TRRS splitter or a USB audio adapter with a combined jack.
How long is the cable, and can it be replaced?
Sony lists a 1.2 m Y-type cord. Sony does not list it as detachable, so plan on a fixed cord and check the listing photos if this matters to you.
Does it block outside noise?
Only passively. The closed design reduces some sound, but there is no active noise cancellation.
Final word
The Sony MDR-ZX310AP does one job: it gives you a light, foldable, wired headset with a microphone for any device with a 3.5 mm jack. Sony’s official specs (30 mm drivers, 24-ohm impedance, 98 dB/mW sensitivity, 125 g) point to a headphone designed for phones and laptops. Buy it for simplicity, not for premium build or noise cancellation. Check the current price of the Sony MDR-ZX310AP on Amazon.in.
