Our Testing Experience

First Impressions

When I first got the Shure SM4 Magnetic Pop Filter, I was curious about how easy it would be to set up. I took it out of the box and immediately noticed the strong magnets, which made attaching it to my microphone quick and hassle-free. I tested it right away by recording some vocal lines, and I could already hear a clear difference in reducing those harsh “p” and “b” sounds. It felt sturdy and well-made, which gave me confidence to keep using it.

Daily Use

Over the next few days, I used the pop filter during my regular podcast recordings and voiceovers. It stayed securely in place thanks to the magnetic design, so I didn’t have to keep adjusting it. I liked that it didn’t block my view of the microphone, making it easy to monitor my positioning while speaking. The filter softened the plosive sounds without making my voice sound muffled, which was a big plus for me.

Key Features in Action

The magnetic attachment was definitely the standout feature. It made switching between microphones or removing the filter super quick, which saved me time. The fine mesh did a great job at stopping pops but still allowed my voice to come through naturally. I also appreciated how slim and lightweight it was, so it didn’t add any bulk or get in my way during recordings.

Long-Term Performance

After using the Shure SM4 for several weeks, I can say it holds up well. The magnets are still strong, and the mesh hasn’t stretched or torn. It continues to reduce unwanted popping sounds without any extra fuss. This pop filter has become a reliable part of my recording setup, and I feel it’s a small but valuable upgrade for anyone serious about clear vocal recordings.
