Frequently Asked Questions

Q: What is an air tube earphone and how does it work?

A: An air tube earphone replaces the final section of wire (closest to the ear) with a hollow acoustic tube. Sound travels through the air inside the tube to reach your ear, rather than through an electrical wire. This design significantly reduces the electromagnetic field near your ear compared to standard wired earphones, making it a popular choice for those seeking low-EMF audio accessories.

Q: Is the FC12 compatible with my smartphone?

A: Yes! The FC12 features a universal 3.5mm audio jack, making it compatible with the vast majority of smartphones, tablets, laptops, and other audio devices that have a standard 3.5mm headphone port. If your device uses USB-C or Lightning, you may need a compatible adapter (sold separately).

Q: Can I use the FC12 for hands-free calling?

A: Absolutely. The FC12 is equipped with a built-in high-grade microphone and an inline control button, allowing you to answer, end, and manage calls hands-free — ideal for use while driving or multitasking.

Q: Does the FC12 have active noise cancellation?

A: The FC12 does not feature active noise cancellation (ANC). However, its in-ear design with soft, snug eartips provides effective passive noise isolation, helping to block out ambient sounds naturally for a more focused listening experience.
