FAQ
What does "Hybrid Dual-Driver" mean? How does it make the sound better?
Our Hybrid Dual-Driver technology means each earphone has two different types of drivers working together to create a better sound.
- A large 11mm dynamic driver produces deep, powerful bass and rich mids.
- A Knowles balanced armature driver delivers very clear and detailed high notes (treble).
By combining them, the A20 PRO earphones give you a much richer and more detailed sound than earphones with only a single driver. You get both powerful bass and sparkling clarity.
Do I need a special headphone amp for the A20 PRO, or can I just use my phone?
No, you do not need a special amplifier. The A20 PRO earphones are designed to be very easy to power. They have a low 16Ω impedance and high 105 dB sensitivity. This means you can plug them directly into any standard device, like your smartphone, tablet, or laptop, and get great volume and high-quality sound.
The cable on these earphones is detachable. Why is that important, and what kind of cable does it use?
The detachable cable design is important for two main reasons:
- Durability: If your cable ever breaks, you can just replace the cable instead of the whole earphone.
- Upgrades: You can change the cable to customize your experience, such as using a Bluetooth cable to go wireless.
The A20 PRO uses the universal 0.78mm 2-pin connector, which is a very common standard, making it easy to find replacement or upgrade cables.
What is the sound style of the A20 PRO? Is it heavy on bass, or more balanced?
The A20 PRO is tuned to have a balanced and natural sound. It is engineered with a "Studio-Tuned Frequency Curve" for monitor-level accuracy. This means it plays music the way the artist intended. Instead of overly heavy bass, you get accurate bass, clear mids, and detailed highs, making it perfect for all genres of music and even for gaming.
How comfortable are the A20 PRO earphones for long listening, and how is the noise isolation?
Yes, the A20 PRO is designed for long-term comfort. The lightweight, ergonomic resin shells are shaped to fit naturally and securely in your ear. We include multiple sizes of silicone eartips to help you find the perfect fit. A good fit creates excellent passive noise isolation (up to 26 dB), which blocks out most background noise so you can focus only on your music.
