These are KZ ZSTX wired earphones. I purchased them on Amazon this October and have enjoyed them about 4 or 5 times. They have high resolution and sound great, but I'm selling them because my Sony headphones are sufficient. All accessories are included. They are practically new, as I haven't used them much and haven't taken them outside. Due to the thickness, I will ship them via Takkyubin Compact. Thank you for your consideration.
