These extension cables were made to provide an added 4-inches of cable length to an existing stereo cable for a major audio company. The item actually sold well enough that we decided to add it to our product line.  Some people just needed a slim profile extension that would allow them to connect different audio equipment together, without having to worry about fitting through the equipment case cover.

This short extension cable can take some punishment and abuse instead of having it put the strain on your favorite earphone or other audio equipment. The price is low enough that you can afford to replace it when needed, rather than have your very expensive gear take all the abuse and punishment. 

It was also designed to fit through the equipment case shells that surround various an audio devices, such as cell phones and tablets.

If you will frequently be connecting and disconnecting a headphone, earphone or some other accessory item and wish to prevent wear-and-tear on the jack of the product you are plugging into, this short extension cable will help to minimize damage to your plug and jack combination.

This EXT-10 short extension can be used with most 3.5mm male stereo plugs (1/8' diameter) that won't fit through narrow opening carrying cases or into a recessed jack. The EXT-10 is perfect for stereo devices that accept a 3-conductor plug and for those needing a similar cable made to fit 4-conductor jacks, we recommend the AEC4 which can be found online here. The AEC4 is often used with cell phones that have a very small hole in their exterior carrying case.

    This extension cable was the answer to the problem of my L-shaped earphone jack not making tight contact with my clip-case-covered iPod. Without it, I would have had to ditch my favorite earphones or my iPod clip-case (it stays in place unlike any other), neither of which I cared to do. Thank you, Scan Sound for coming through with a good solution and great product.
