As a phone enthusiast and a frequent user of various iPhone cases and accessories, I've noticed something interesting – these items can significantly affect the microphone quality of your iPhone

In this post, I'm going to share my insights and experiences on how different cases and accessories can influence the sound quality during calls or recordings. It's a topic that might seem trivial at first, but trust me, it's more important than you might think!

iPhone Cases: A Double-Edged Sword

When we buy a case for our iPhone, the main goal is usually to protect our precious device from drops and scratches. But did you know that some cases can actually interfere with the microphone? I learned this the hard way. Once, I bought this super stylish, heavy-duty case. It looked amazing and felt sturdy. But then, I started noticing that people had a hard time hearing me during calls. It took me a while to realize that the case was the culprit!

How Cases Affect Sound Quality

  • Material Thickness: Thick materials can muffle the microphone.
  • Design Flaw: Some cases might block the microphone holes.
  • Quality of Case: Cheaper cases might not be designed with the microphone in mind.

Accessories That Make a Difference

Screen Protectors

I never thought a screen protector could affect microphone quality, but it can! If it's not properly aligned, it can partially cover the microphone hole near the bottom of the iPhone. Always ensure it's correctly placed.

PopSockets and Grips

These handy accessories are great for a better grip, but if placed incorrectly, they can cover the microphone. Be mindful of where you stick them.

External Microphones

For those who do a lot of video recording or streaming, external microphones can enhance audio quality significantly. They bypass the iPhone's built-in mic, offering clearer and more professional sound. I wrote an article reviewing the best external microphones for your iPhone.

Personal Experiences and Tips

I experimented with different cases and accessories, and here's what I found:

  • Slim Cases Work Best: They usually don’t interfere with the microphone.
  • Watch for Mic Cutouts: Always check if the case has proper cutouts for the microphone.
  • Be Mindful with Accessories: Placement is key. Don’t obstruct the mic!


The impact of iPhone cases and accessories on microphone quality is real. While protecting our iPhones is important, we also need to ensure that we're not compromising on functionality, especially when it comes to sound quality. Always check the design and placement of any case or accessory you use. Your iPhone's microphone will thank you!
