5mm headphone cable. It just costs less than 50 bucks. Its to hard to send the product back from here. Very quiet headphones. Be aware the built in microphone is terrible and pretty much unbearable when driving. gebaut. So comfortable and light to wear. If you have a wide foot like me, just wear them for a day or two and they will break in. No pain, no discomfort, just a nice snub earful of earbuds! I will say it was stronger than my Galaxy Buds, so theres that (and I was REALLY disappointed in those).
