Top 5 Aftermarket Speaker Upgrades for Cardo Helmet Systems
For motorcycle enthusiasts using Cardo communication systems, upgrading speakers can dramatically improve audio clarity, noise isolation, and overall riding experience. While Cardo units come with decent stock speakers, many riders seek better sound quality for music, navigation, and intercom communication. This guide provides objective comparisons of the best aftermarket options based on technical specifications, user feedback, and real-world performance1.
Why Upgrade Your Cardo Speakers?
Cardo’s built-in audio systems work well out of the box, but have limitations in noisy environments. The 3.5mm auxiliary port on all Cardo units enables compatibility with third-party audio solutions1. Upgrading provides:

- Enhanced noise isolation at highway speeds
- Improved bass response for music enjoyment
- Better voice clarity for intercom communication
- Customizable fit for different helmet types
Top Aftermarket Speaker Options Compared
Based on extensive user testing and technical analysis, these five options deliver the best performance for Cardo systems:
| Product | Impedance | Sensitivity | Frequency Range | Price Range |
|---|---|---|---|---|
| JBL 45mm Audio Set | 32Ω | 105dB | 20Hz-20kHz | $99-$129 |
| Etymotic ER2XR | 17Ω | 109dB | 20Hz-17kHz | $149-$179 |
| Plugfones Pro | 16Ω | 102dB | 20Hz-18kHz | $79-$99 |
| AudioTech Helix | 32Ω | 100dB | 20Hz-22kHz | $129-$159 |
The table reveals important technical differences between options. JBL and AudioTech offer wider frequency ranges ideal for music enthusiasts, while Etymotic provides superior sensitivity for clearer voice communication. Plugfones strikes a balance with effective noise suppression at a more accessible price point12.
Detailed Product Analysis
JBL 45mm Speakers
Cardo’s official JBL upgrade kit delivers noticeably better bass response and overall audio quality compared to stock speakers1. Users report “much better sound than the Sena Harmon Kardon speakers” when properly configured. Critical to success is loading the updated JBL profile in the Cardo Connect App, which optimizes audio processing for these speakers1.
Etymotic Precision Earphones
These high-fidelity earphones provide “incredible bass response given their small size” and exceptional noise isolation2. The 17Ω impedance matches well with Cardo’s output, and users report significantly improved voice clarity for intercom communication. The deep insertion design blocks approximately 35dB of ambient noise, making them ideal for highway riding2.
Plugfones Noise-Suppressing Earphones
“Plugfones cut down a bit of noise to protect aging ears and provide good audio from Bluetooth connections,” according to long-term users3. Their interchangeable foam and silicone tips ensure comfortable fit across different helmet types. The 16Ω impedance provides excellent compatibility with Cardo systems without requiring additional amplification3.
Installation Tips for Optimal Performance
Proper installation significantly impacts performance. “Try moving the speakers around in the helmet pockets… It took some fiddling with mine,” reports one experienced user1. Position speakers as close to the ear canal as possible without causing discomfort. For earphone solutions, ensure proper seal for maximum noise isolation. Always update your Cardo firmware and apply the appropriate audio profile through the Cardo Connect App after installation1.
Frequently Asked Questions
