Understanding iPhone Microphone Basics
Every iPhone model contains at least one microphone, though newer models include multiple microphones positioned in different locations. These microphones work together to capture audio when you're making calls, recording videos, or using voice features like Siri. Understanding where these microphones sit on your device helps explain how your iPhone processes sound and why audio quality varies depending on how you hold your phone.

The primary microphone on iPhones serves as the main audio input device. This microphone converts sound waves into digital signals that your phone can process and transmit. When you're on a call, this microphone captures your voice. When you're recording a video or memo, it records the surrounding audio. Modern iPhones use advanced microphone technology that filters out background noise and focuses on the sound directly in front of the device.
Apple designs iPhone microphones with specific purposes in mind. Some microphones handle voice calls, while others manage video recording or environmental audio capture. The placement of multiple microphones allows the phone to use directional audio technology. This technology helps distinguish between the sound you want to record and unwanted background noise, which is why your voice typically sounds clearer during calls even in noisy environments.
Different iPhone generations have different microphone configurations. Earlier iPhone models had single microphones, while iPhone 6s and later models introduced dual or triple microphone systems. Understanding your specific iPhone model helps you know exactly how many microphones your device contains and where each one is positioned.
Practical Takeaway: Your iPhone has multiple microphones working together to capture and filter audio. Knowing your model helps you understand its audio capabilities and limitations.
Locating the Bottom Microphone
The most noticeable iPhone microphone is located at the bottom of the device, near the charging port. On iPhones with a Lightning connector, you'll find the microphone opening positioned just to the left or right of the charging port (the exact placement varies by model). On newer iPhones with USB-C connectors, the microphone sits in a similar position relative to the charging port. This bottom microphone is typically the primary microphone used for phone calls and primary audio recording.

When you examine the bottom of your iPhone, you'll see small speaker grilles and microphone openings. The microphone opening appears as a small circular or rectangular hole in the metal or plastic bezel. It's considerably smaller than the speaker grille next to it. The speaker grille has a much larger opening with multiple tiny holes arranged in a grid pattern, making it easy to distinguish from the microphone opening once you know what to look for.
This bottom microphone positioning makes practical sense for several reasons. When you hold your phone naturally during calls, your mouth is positioned relatively close to the bottom of the device. This proximity allows the microphone to capture your voice clearly without requiring you to hold the phone in an awkward position. Additionally, having the microphone at the bottom keeps it away from your fingers, which might otherwise block the audio input during calls.
The bottom microphone also serves a secondary purpose in video recording. When you record video while holding your phone in landscape or portrait orientation, this microphone captures the primary audio track. If you're recording someone speaking directly in front of your phone, this microphone captures their voice along with ambient sound from that direction.
Practical Takeaway: The bottom microphone near your charging port is your iPhone's primary audio input. During calls, keep this area unblocked for the clearest voice transmission.
Identifying Top and Side Microphones
Modern iPhone models, particularly the iPhone XS, iPhone 11, iPhone 12, iPhone 13, iPhone 14, iPhone 15, and later generations, include additional microphones positioned at the top and sides of the device. These secondary microphones work in combination with the primary bottom microphone to provide noise cancellation and directional audio recording. The top microphone is typically located near the speaker that faces upward when you hold the phone in portrait mode.

To locate the top microphone on your iPhone, look at the very top edge of your device. You'll see a small opening similar to the one at the bottom. This microphone is particularly important for phone calls because it helps cancel out background noise. During conversations, your iPhone uses both the bottom and top microphones to create a noise-cancellation effect. The system analyzes audio from both microphones and intelligently filters out sounds that aren't your voice.
On some iPhone models, you'll also find microphone openings on the sides of the device. These are often located near the volume buttons or on the frame between the camera modules and the volume controls. Side microphones contribute to the directional audio recording capability. When you're recording video, these microphones help capture audio from specific directions while reducing unwanted sounds from other directions.
The multiple microphone system represents a significant advance in iPhone audio technology. Rather than relying on a single microphone, Apple's approach uses several microphones positioned strategically around the device. Software algorithms then combine the audio signals from all microphones, applying filters and processing to enhance the audio you want while suppressing background noise. This technology is why calls often sound clear even in noisy environments like airports or busy streets.
Each iPhone model generation may have slightly different microphone placement. iPhone 14 Pro and Pro Max models, for example, have different microphone configurations compared to standard iPhone 14 models. Checking your specific model in Apple's technical specifications provides exact information about microphone count and positioning.
Practical Takeaway: Your iPhone likely has microphones in multiple locations working together for noise cancellation. Avoid covering any of these areas during calls or video recording for optimal audio quality.
Microphone Locations by iPhone Model
iPhone models released between 2007 and 2014 typically had a single microphone located at the bottom of the device. The original iPhone through iPhone 5s contained just one microphone opening. Starting with iPhone 6s in 2015, Apple introduced a dual-microphone system. The iPhone 6s added a second microphone at the top of the device, enabling noise cancellation technology for the first time on iPhones.

iPhone 7, iPhone 8, and iPhone X models continued the dual-microphone design with one microphone at the bottom and one at the top. These models refined the noise cancellation algorithms to make background audio filtering even more effective. iPhone XS, iPhone XS Max, and iPhone XR introduced a triple-microphone system. In addition to the bottom and top microphones, these models added a third microphone on the device's frame, typically positioned between other components.
iPhone 11 models maintained the triple-microphone configuration from the previous generation. iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max continued with three microphones positioned at the bottom, top, and side of the device. iPhone 13 series phones kept the same microphone arrangement. iPhone 14, iPhone 14 Plus, iPhone 14 Pro, and iPhone 14 Pro Max also maintained the established microphone configuration, though the Pro models include additional audio processing capabilities.
iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max continue Apple's multi-microphone approach. All current iPhone models use at least two microphones, with most current models using three or more. This consistency in design means that newer iPhones share similar microphone placement principles, though specific positioning may vary slightly between standard and Pro models.
A useful way to identify your iPhone model is through Settings. On your iPhone, go to Settings, then General, then About. Look for the "Model Name" field, which tells you your exact iPhone version. Once you know your model, you can reference Apple's official specifications to learn the precise number of microphones and their locations. This information proves helpful if you're troubleshooting audio issues or simply want to understand your device better.
Practical Takeaway: Microphone configurations changed significantly around 2015 when dual-microphone systems became standard. Check your model name in Settings to determine your specific microphone setup.
Visual Guide to Finding Microphone Openings
Locating microphone openings requires knowing what to look for, since they're intentionally designed to be subtle and blend with your device's aesthetics. Microphone openings appear as small holes ranging from 1mm to 3mm in diameter. They're typically circular or slightly oval in shape. Unlike the speaker grille, which has a grid of holes, microphone openings appear as single, relatively isolated holes
