Benefits of the Sennheiser MKE 40 Microphone

When it comes to work, play, or online communication, choppy vocals are not something you want to risk. The Sennheiser MKE 40 clip-on microphone is lightweight, portable, but most importantly, reliable. Here’s why we love it.

Industry-Leading Brand

Brand names aren’t everything, but they can certainly tell you a lot about a product. Sennheiser has been an industry leader for decades, producing headphones, microphones, and wireless audio systems that have elevated the world of professional recording to new heights.

Thanks to its reputation and status as a pioneer in the field of audio recording and sound system engineering, Sennheiser assures that each of its products is quality-controlled and perfect for professional use. The MKE 40 is no exception, as it’s a high-performing, reliable lapel that has been praised by professionals across the globe.

No More Unwanted Sounds

Perhaps one of the largest and most persistent problems that sound engineers and researchers are trying to solve is the reduction of unwanted noise. The MKE 40 utilizes a cardioid pickup pattern which helps minimize the signal-to-noise ratio and reduce unwanted sounds.

Perfect for onstage conditions, the MKE 40’s pattern allows it to consistently reject feedback and offer crisp vocals and accurate bass reproduction to boot. Because of this, musicians, live performers, and lecturers alike can attest to the mic’s reliability even in loud environments.

Intelligible Speech

Finally, another great feature of the MKE 40 is its ability to produce clear, intelligible speech that can be understood from one end of the room to another.

For this, we have multiple factors to thank, but one of them is its high gain levels which pick up on distinct vocal tones and clarifies them, reducing popping or muted consonants. But while it does have high gain, it is able to reject feedback, removing ear-splitting static from the equation.
