Xundd W009 Bluetooth Wireless Ear Clip Open Design Non-In-Ear Sports Bone Conduction Earphones Long Battery Life Waterproof

For this price, the quality, sound, and comfort are really impressive for a domestic product. I've tried open-back headphones from another brand, but these are way more comfortable. They fit well and feel secure, and the music sounds pure and clear without any noise or static. The craftsmanship is excellent and very detailed. I honestly didn't expect such quality at this price, so I can definitely recommend them!
