Frequently Asked Questions
What are air tube headphones?
Air tube headphones use hollow tubes instead of wires for the last section near your ears. Sound travels through air in the tubes rather than through metal, which eliminates EMF radiation from reaching your ear canal. Your phone connects normally through a standard wire — only the final few inches are replaced with radiation-free air tubes.
Do air tube headphones sound as good as regular headphones?
Modern air tube headphones deliver audio quality comparable to standard wired earbuds in the same price range. The SYB Air Tubes are specifically engineered for premium-like audio with clear mids and highs. Bass response is slightly different due to the air tube design, but most users find the sound quality excellent for music, calls, and podcasts.
Can I use air tube headphones with my iPhone?
Yes. If your iPhone has a headphone jack (iPhone 6s and older), use the 3.5mm version. For newer iPhones with only a Lightning port, use the 3.5mm air tubes with Apple's Lightning-to-3.5mm adapter (sold separately by Apple). For iPhone 15 and newer with USB-C, choose the USB-C version directly.
Are air tube headphones safer than Bluetooth earbuds?
Air tube headphones eliminate EMF radiation from reaching your ears entirely — the hollow tubes carry sound through air, not electrical signals. Bluetooth earbuds like AirPods place a radio transmitter directly in your ear canal, emitting RF radiation continuously while in use. For reducing EMF exposure to your head and brain, air tubes are a significantly safer alternative to any wireless headphone.
What's the difference between SYB Air Tubes and AvalonX?
Both are quality air tube headphones available in 3.5mm and USB-C. The SYB Air Tubes are our flagship with premium audio engineering and a built-in microphone optimized for calls. AvalonX offers an earbud-style alternative with a different ear fit profile. Since ear shapes vary, some people find one brand more comfortable than the other. Both deliver the same EMF protection benefit.
