This Kitbon adapter is only optic audio is pulses of light, not electrical signals. This is not a simplex converter to majically transform optical (light waves) Toslink outputs from tvs or other devices to a headphone jack (electrical signals).

There are two types of optic cables. The standard Toslink (a fairly square plug with a key) and the mini 1/8" (3.5mm) round plug. All this device does, and all it was ever suppose to do, was convert the Toslink output from a device to a mini optical cable. Period.

This adapter simply converts a 3.5mm round OPTIC cable to a standard Toslink OPTIC cable.
IT WILL NOT ADAPT THE OPTIC OUTPUT TO A HEADPHONE OR OTHER STANDARD AUDIO OUTPUT! In order to do that you need a device such as this: "Digital Optical Coax to Analog Stereo Audio Converter, USB DAC Headphone Amplifier".
Increase sound quality by significantly plummeting signal jitter and optical distortion with the Toslink Jack to Mini Plug Optical Adapter which features graded index optical fiber.
The Toslink to Mini Optical Adapters provide high quality digital audio transmission in Dolby Digital, Dolby Digital Plus, S/PDIF, DTS, and other digital audio formats. Eradicate complications associated with electrical grounding noise to grant superior audio clarity by using the Toslink to mini optical adapter.
Connector comes with a dust cap for protection from contamination while not in use.
