Play music on your headphones, Hi-Fi system, or automobile stereo from any phone, tablet, iPod, laptop, or other media player that has a standard 3.5mm aux port. This is known as universal compatibility. Superior Audio Quality: constructed using the same high-quality materials as high-end headphones. The purest audio quality is guaranteed by 24K gold-plated contacts. Amazingly Sturdy: With four feet of flexible, durable cord, a premium metal housing, and a bend lifespan of over 10,000, this cable is made to last—many times longer than original audio cables. Excellent Fit: Unlike standard aux cables, ultra-slim extensions to the aux jacks allow use with almost any phone or tablet case. Cases don't need to be taken out while in use.
