If you want an inexpensive wired in-ear set with a built-in mic for calls and classes, choose Sony MDREX15AP; if you need the same core sound without a mic and prefer a lighter, simpler plug-and-play pair for college students, choose SONY MDREX15LP.
These two Sony models look almost identical on paper, and that is exactly why buyers get stuck. Both are wired 3.5 mm in-ear headphones built around 9 mm dynamic drivers and hybrid silicone tips. The real decision comes down to one feature: the microphone and inline control on the MDREX15AP, and the plug-and-play simplicity of the MDREX15LP.
• Sony MDREX15AP — biggest strength: Built-in mic plus integrated media control, so it doubles as a headset for calls, video lectures and online classes.
• Sony MDREX15AP — biggest trade-off: The inline remote and mic add a bit of hardware and bulk versus a plain cable, and it lists a shorter 90-day warranty.
• SONY MDREX15LP — biggest strength: Same 9 mm neodymium driver recipe and hybrid silicone fit, with a lighter overall build and a 1-year warranty.
• SONY MDREX15LP — biggest trade-off: No microphone and no inline control, so it is music-only.
• Who each pick is for: The MDREX15AP is for anyone who takes calls or joins meetings on a laptop or phone; the MDREX15LP is for someone who just wants a no-fuss wired pair for music, podcasts and gaming audio.
The MDREX15AP is the more versatile of the two. Sony built it around a 9 mm dome-type dynamic driver paired with high-energy neodymium magnets, and the spec sheet describes the result as clear treble and midrange with a strong bass response. The frequency range is listed as 20 Hz to 20,000 Hz, with 32 ohm impedance and 100 dB sensitivity — numbers that tell you it is easy enough to drive from a phone, tablet or laptop headphone jack without needing a separate amp.
The comfort story is the same across both models: hybrid silicone earbuds in small, medium and large sizes so you can dial in the fit, and a Y-type cord with a slider to keep things from tangling in a backpack. Sony notes that if the tip size does not match your ear canals, sound quality and call performance will suffer — worth remembering, since fit drives everything with in-ears.
Buy the MDREX15AP if you want one wired pair that handles music and voice. Skip it if you already own a dedicated headset or never take calls on wired earphones, because you would be paying for a mic you will not use. One more thing to weigh: the warranty is listed at 90 days, which is shorter than the LP's.
SONY MDREX15LP: Who It's For
The MDREX15LP is the stripped-down sibling. It uses the same foundation — 9 mm dome-type driver units, high-energy neodymium magnets, hybrid silicone earbuds, and a Y-type cord with a slider to fight tangling. The frequency range is listed as 20 Hz to 20,000 Hz with 100 dB sensitivity, and the impedance is a notably low 16 ohm. Lower impedance generally means the drivers demand less from your source, which is a small plus if you plug into weaker outputs.
The big difference is the model name itself: the LP is a no-mic design. Sony's own style listing calls it "3.5mm Aux, No Mic," so there is no inline microphone and no call control. It is a music-first pair. The cable is listed at 120 cm, which is a practical length for a phone in a pocket or a laptop on a desk.
Sony also lists a 1-year warranty here, versus the AP's 90 days, and bundles ear cushions alongside the headphones. If you want a simple, light wired set that just plays audio — commuting, studying, plugging into a console controller for gaming audio — this is the cleaner choice. Buy the MDREX15LP if you want pure audio playback and a longer warranty. Skip it if you need to take calls, since there is simply no mic to do it with.
• Best for calls and online classes → Sony MDREX15AP. It is the only one of the two with a microphone and integrated media control.
• Best for pure music and podcasts → SONY MDREX15LP. No mic, no inline remote, nothing extra to think about.
• Best for gaming audio on a controller or PC → SONY MDREX15LP for listening, but switch to the MDREX15AP if you also want to talk in voice chat, since gaming headphones for college students usually need a mic.
• Best for low-impedance, easy-to-drive playback → SONY MDREX15LP. Its 16 ohm rating asks less of your source than the AP's 32 ohm.
• Best warranty coverage → SONY MDREX15LP, listed at 1 year versus 90 days on the AP.
• Best all-rounder for a student → Sony MDREX15AP. One pair that covers music, lectures and calls beats two single-purpose pairs.
• Best for a minimalist who already has a headset → SONY MDREX15LP. No redundant mic hardware.
• Tie on fit and cable management → both. Hybrid silicone tips in three sizes and a Y-type cord with slider appear on both sheets.
In my opinion, most people should buy the Sony MDREX15AP. The microphone and inline control are the only meaningful functional difference between these two, and they turn a basic pair of earphones into something that works for calls, online classes and voice chat as well as music. For a college student who wants one wired pair to cover everything, that flexibility is worth more than the LP's lighter build and longer warranty.
I would only pick the SONY MDREX15LP if you are certain you will never take a call on wired earphones, or if you specifically want the lower 16 ohm impedance and the 1-year warranty. Otherwise, the AP is the safer buy.
FAQ
No. Sony lists it as a "No Mic" style, so it is for listening only. If you need to make calls, choose the MDREX15AP instead.
For pure game audio, either works, and the MDREX15LP's lower 16 ohm impedance makes it slightly easier to drive. But if you want to talk to teammates, the MDREX15AP is the one with a mic.
The SONY MDREX15LP is listed with a 1-year warranty, while the Sony MDREX15AP is listed at 90 days.
