It sounds like there’s a bit of confusion here— to clear things up!
On the bottom of your iPhone 15 Plus (and most modern iPhones), there are a few physical features:
- Speaker grilles: The row of small holes on one side (usually the right) is the bottom speaker.
- Microphone holes: The smaller set of holes on the left side.
- USB-C port: In the center—used for charging, data transfer, and connecting accessories.
Older iPhones (like the iPhone 6S and earlier) had a 3.5mm headphone jack, but that was removed starting with the iPhone 7. Since then, wired headphones need to connect through the charging port—now USB-C on the iPhone 15 models—using compatible USB-C headphones or an adapter.
So no, those small holes on the bottom of your iPhone aren’t for headphones—they’re the speaker and microphone! If you saw photos suggesting otherwise, they’re likely either older models or a bit of confusion from angles making it look like the holes are for something else.
