Amazon.com Product Description:
Maxell's HP20 headphone extension cord gives you the options you need to connect your headphones to nearly any output setup. A 20-foot coiled cord expands and retracts to give you more mobility while using less space. A dual-pin airline adapter, 0.25-inch stereo adapter, dual headphone adapter, and mono adapter are included.

Rating : - Great value and durable too.
I needed an extension cord to attach to my earbuds to give me more mobility while connected to the computer. I no longer consider Sony a choice for anything due to their rapidly declining build quality in the past couple years. I was hesitant on this purchase but the price was right so I went for it. I've been using them for over a month now and am very pleased with the product. Yeah, I know it's a headphone extension cord but there seem to be few viable options on Amazon.com and I wanted to let people know that this is a worthy purchase.
