Frequently Asked Questions
Everything you need to know about this microphone
Excellent question! While your built-in mic does its job, it's often positioned far from you and picks up lots of engine noise. Our external mic sits perfectly close to your mouth with advanced noise filtering - you'll experience crystal-clear calls every time. Your callers will love the difference, especially during highway drives. As one happy customer shared: 'My wife finally stopped asking me to repeat myself!'
Absolutely! If you have an aftermarket Android head unit with a 3.5mm mic input (which nearly all do), you're all set! It's truly plug and play - simply connect it to the MIC port on your harness and you're ready to go. It works beautifully with any brand, not just Brummstadt. If you'd like to double-check compatibility, we're here to help - just send us a quick message with your head unit model.
You'll find the 3.5mm MIC port in your wiring harness (typically located with the RCA connectors and clearly labeled 'MIC'). Simply push the connector in until you hear a satisfying click - and you're done! No cutting, no splicing, just pure simplicity. The whole process takes about 30 seconds.
The sun visor is a customer favorite - the clip holds securely and positions the mic perfectly. That said, anywhere within about 30cm of your mouth will give you excellent results. The A-pillar works wonderfully for taller drivers, while mounting above the rear-view mirror creates a clean, professional look. With our generous 3-meter cable, you have the flexibility to choose the perfect spot for your setup!
You'll experience a remarkable improvement! Your callers will immediately appreciate the clarity - no more repeating yourself or raising your voice. Our advanced noise filtering effectively reduces road and engine noise. Highway conversations? Crystal clear. Voice commands? They'll work reliably every time. While we can't claim miracles, the enhancement over built-in mics is truly impressive. Many customers tell us it's the best value upgrade they've added to their setup.
Most of the time, it works perfectly right out of the box! If you'd like to fine-tune it, simply navigate to Settings → Sound → Microphone Gain. We recommend starting at 50% (ideal for most vehicles). Driving a diesel? Try 70% for optimal clarity. Have a quiet EV? 40% might be perfect. It takes just moments to find your ideal setting.
Yes, absolutely! Voice commands become a pleasure to use. Whether it's 'Hey Siri, call home' or 'OK Google, navigate to...', they'll respond reliably during your daily drive. Even at highway speeds, you'll only need to speak normally rather than raising your voice. The strategic positioning near your mouth truly transforms the voice command experience.
Yes indeed! When you select 'add microphone' with any Brummstadt head unit order, this is the exact premium microphone you'll receive. Same exceptional quality, same generous 3-meter cable, same outstanding noise filtering. Purchasing it separately simply gives you the flexibility to enhance any head unit, regardless of where you bought it.
Great news - our noise filtering technology excels in louder vehicles! Whether you drive a diesel ute, work van, or classic 4WD, you'll notice a significant improvement. We recommend adjusting the mic gain slightly higher (around 60-70% instead of 50%) and positioning it away from air vents for best results. While we're realistic about expectations, your call quality will be noticeably clearer than with standard built-in mics.
We're so confident in this microphone that we offer our 30-day satisfaction guarantee. Here's something we're proud of: in over 3 years, we can count the returns on one hand. Once customers experience the improvement, they're genuinely delighted. Plus, you're protected by our comprehensive 3-year warranty - the same premium coverage we provide for all our products.
While it's technically possible, we'll be honest - it's not very practical. Once properly installed with cables neatly routed behind trim pieces and connected to your head unit, relocating it requires quite a bit of work. Most customers with multiple vehicles find it more convenient to equip each car with its own microphone - it's worth the investment for the convenience!
While optimized for the driver's voice, your passengers will still be heard clearly during group calls. For the best all-around coverage, consider mounting it centrally on the rear-view mirror. Our versatile rotatable clip allows you to find the perfect angle for everyone. It's ideal for those memorable family road trip conversations!
