Headphone Adapters

We have Headphone and earphone adapters for smartphones, portable audio devices and home audio. 1/4" to 3.5mm, Y adapters and more.

1/4" is the standard size headphone jack/plug for Stereo and Surround Sound Receivers and Home Stereo Amplifiers. It's the same size as used for Guitar cables and Musical instrument cord connectors.

The 3.5mm (1/8") Mini phone plug is used on iPods and MP3 players and most types of small electronics that have sound.

The 2.5mm connector was used by many early cell phones. It looks the same as a 3.5mm connector, only skinnier.


RCA connectors are used on the back of most Home Theater equipment, cable boxes, etc. Generally used for "Line level" not headphone level Inputs/Outputs
