Best Car Stereo Microphones for 2022

If you spend a lot of time in traffic, a good car stereo microphone can vastly improve the quality of your phone calls while keeping you safe on the road. Holding your phone to talk while you drive can be dangerous (and illegal). Most car stereos today have Bluetooth, but the microphones are usually not that great — they have a hard time picking up voices from the passenger seat or when there’s lots of traffic noise.

You could upgrade your stereo, but that option can cost several hundred dollars and may not improve your sound quality much. The best solution is a separate microphone, which is easy to install if your car stereo uses Bluetooth or has an aux connection, similar to a headphones connector on your phone. Then it’s a matter of mounting the microphone where it can easily pick up voices.

The best car stereo microphones on this list are all easy to set up, provide great sound quality, and are inexpensive.

How We Picked the Best Car Stereo Microphones

To pick the best car stereo microphones we looked at the different types of wired and wireless options. The most common input types are Bluetooth, as well as 3.5mm and 2.5mm input jacks. Then we compiled a list of the ones with those input types that received top ratings and reviews from industry experts and individual consumers.

Next we evaluated the top rated car stereo microphones based on the following criteria:

  • Sound quality: To compare sound quality we evaluated microphone sensitivity, signal to noise (SNR) ratio which measures audio performance in terms of noise, signal quality, and fidelity, and the effectiveness of its noise filtering capabilities. A good voice microphone should have an SNR rating of at least 52 dB.
  • Polar Pattern: A microphone’s polar pattern determines how easily it picks up sound based on the position around the microphone. Car microphones should be omnidirectional to pick up voices from the driver and any passengers.
  • Ease of installation & use: There’s more to using a car stereo microphone than just hooking it up. The length of the cord and mounting options determine microphone placement which directly affects sound quality.

Finally, cost was considered as a tie-breaker.

Best Overall 3.5mm: PowerDeWise Lavalier Clip On Microphone

Clip It On. PowerDeWise

Why It Made The Cut: The PowerDeWise Lavalier Clip On microphone is not only a great microphone for your car but a great option for professional-quality recording.

Specs:
— Signal to Noise Ratio: 76 dB (decibels)
— Input: Auxiliary
— Polar Pattern: Omnidirectional

Pros:
— Professional quality sound
— Universal compatibility

The 6.5-foot extension cord is shorter than the ones offered by other microphones but is adequate for most vehicle applications. Where the PowerDeWise stands out, though, is in providing pro-grade audio quality. The microphone features a wind muff instead of a foam cap, and its sound quality is good enough to use for podcasts or video recordings.

As far as microphones go, the PowerDeWise is expensive and may even be overkill if you only plan to use it in the car. But as an all-around professional quality microphone, it is a bargain.

Its 15-foot cord is one of the longest for car mics, but could be useful in larger vehicles like SUVs or vans. The mic is easy to attach to a sun visor or other mountable surface.

The sound quality is strong thanks to the omnidirectional mic, but some users said that they sounded as if they were sitting away from the microphone. Even so, Alphasonik offers a 60-day money-back guarantee, so if you have this issue, or are not 100 percent satisfied, you can return it within that time period for a full refund.

Things to Consider Before Buying a Car Stereo Microphone

Microphones are fairly uncomplicated devices that have a minimum of setup compared to other electronics in your car. Even so, there are a few things to consider before buying one.

Input Type: Microphones either have a wired 3.5mm or 2.5mm auxiliary connection or a wireless Bluetooth connection. Bluetooth-compatible microphones will work with just about any smartphone and any car stereo with a Bluetooth connection. The only challenge with the Bluetooth is setting it up to work with either your phone or car stereo.

Wired connections can be confusing. The most common auxiliary connection is the 3.5mm, but 2.5mm jacks have become increasingly popular for things like headsets and smaller audio or video equipment. Should you have one type of jack but need the other, you can either order another microphone with the correct jack or an adapter. Both options cost about the same amount of money.

Signal to Noise Ratio (SNR): The signal-to-noise ratio measures the performance of an audio system in terms of noise, signal quality, and fidelity. The ratio is calculated using the strength of the audio system and comparing it to the base level of noise in the system.

SNR is measured in decibels (dB). A higher dB rating is better for audio quality purposes when making a recording but not critical for car microphones which translate audio into a digital signal. Most car stereo microphones have at least a 55 dB SNR rating to minimize the possibility of picking up hiss or background noise when there is no signal or voice present. Additionally, they have noise reduction or signal processing technology to help further reduce any background noises.

Polar Pattern: The microphone’s polar pattern measures the variation in sensitivity and response based on your position around the microphone. Microphones have different polar patterns for different applications. Car microphones are almost always omnidirectional, meaning they have the same response at all angles around the microphone.

FAQs

Q: How can I improve my microphone quality?

There are several things you can do to improve your microphone’s quality including:

— Turn off anything noisy in the car
— Close your windows and sunroof
— Keep the microphone of your dashboard, or if possible, mount it on a visor
— Keep your microphone positioned close to your mouth.

Q: Why does my car mic sound muffled?

A muffled sound can stem from internal problems or a bad connection to your stereo. However, it could also be caused by the location and mounting of your microphone, or the result of your environment.

Q: What is a good microphone sensitivity?

At minimum, a car stereo microphone should have an SNR rating of 55 dB or better. This helps to minimize any hiss or background noise.

Q: Are car stereo microphones worth it?

Car microphones are a cheap investment and much less expensive than replacing your car stereo and built-in microphone. In the reviews of the best car stereo microphones, most people who purchased one felt it significantly improved the audio quality of their calls compared to using their phone alone, or using the car’s built-in microphone.
