Review on Qaoquda 5Ft Gold Plated 3.5MM Male to Female AUX Audio Spring Coiled Spiral Extension Cable Black (TRRS 3.5M/F) - Three-Channel Stereo Input, 90 Degree Angle by Kevin Gray

Requires Pioneer High-Res Headphone Extension Cable. I was skeptical about the audio quality of the cable but was impressed with how well it retained the original audio quality. The cable produces no hum or other noticeable audible interference. It should be noted that this cable is only about 1 foot long when at rest, but can stretch about twice as much as the cable is twisted, but you will likely be uncomfortable using it that way. It's worth it if you need a little upgrade for your audio gear.
