What it is

The No Sew FC1203-NEW-US earbuds use air-tube technology to deliver stereo sound from speaker cases positioned away from the ears. They connect through a standard 3.5mm CTIA plug and include an inline microphone with media controls for calls and playback. The package supplies three sizes of silicone ear tips and a travel case.

Installation and common issues

Plug the 3.5mm jack into any CTIA-compatible port on a phone, tablet, laptop or MP3 player; no driver or power supply is required. Select the ear-tip size that seals your ear canal to activate the noise-isolating fit. The only frequent issue is a loose seal if the wrong tip size is chosen, which reduces bass response and isolation.

Who it suits and who should look elsewhere

These suit listeners who want a wired in-ear headset with a microphone and active noise cancellation for commuting, office calls or casual music. They are not for buyers who require a wireless Bluetooth connection, a USB-C or Lightning digital interface, or a detachable cable for replacement.

Questions about this item

How can I tell the air-tube earbuds are working correctly after plugging them in?

Insert the 3.5 mm plug fully into the CTIA port, play audio and verify sound travels through the air tubes to both ears; the inline microphone should pick up your voice clearly during a test call.

What comes in the box and what must I purchase separately?

The package includes the FC1203-NEW-US earbuds with medium silicone tips installed, plus small and large tip pairs and a travel case; a 3.5 mm adapter for non-standard ports is not included.

Which version should I choose — FC1203-US or FC1203-NEW-US?

Select the FC1203-NEW-US model; it is the current air-tube headset with 40 ohm input impedance, 140 ohm microphone impedance, active noise cancellation and a 21 gram weight.
