No instruction manual. [Product Description] Quoted from the website: Ultra-lightweight 12g earphones minimize the burden on the ears, so you won't feel stressed even after wearing them for a long time. Comes with three sizes (S/M/L) of ear tips, which fit your ears perfectly and provide excellent comfort. Excellent sound isolation allows you to hear the sound clearly even when used outdoors, making them ideal for commuting to school or work. Balances low to high frequencies, faithfully reproducing the sound source. To prevent resonance, speakers with excellent vibration damping are used, achieving clear sound. Even with a lightweight design, you can enjoy powerful bass. Uses corrosion-resistant, acid-resistant, and durable aluminum, and further employs highly elastic TPE to create a coating for the cord, improving durability and preventing disconnection. The core of the cord is made of oxygen-free copper wire and ABS insulation. Without touching your smartphone, you can answer/end/reject calls, play/pause music, and skip/rewind tracks by pressing the button. The remote control is equipped with a microphone, allowing for hands-free calls and real-time conversations during games. [High Compatibility] Uses a high-quality 3.5mm plated plug. I haven't used it, so I can't answer any other questions. 38-16
