【High quality durability】With high quality gel material, it fits perfectly to the wearer's head even when using glasses, ensuring good sealing. The memory foam has a high energy absorption ability and can slowly bounce back after it is pressed and resists compression. The PU leather is not only skin-friendly, but also very durable and is not attacked by skin grease or sweat. 【More convenient installation process】 It is perfectly compatible with Green Devil's Shield and 3020 series. Without using any special tools, you can simply remove the old ear pads and put on the new ones to complete the replacement. In addition, the package includes a detailed step-by-step guide to help you with the installation. 【Exceptional comfort experience】 Compared to general ear pads, this ear pad is carefully crafted from softer leather and gel, and the noise reduction capacity has been significantly improved. You can relax in an excellent environment with noise insulation and enjoy the safe and comfortable audio world. 【Long wear time without worries】 This ear pad effectively reduces the pressure between the ear muscle and the ear and finds an ideal balance between comfort and durability. The design is designed to minimize the inconvenience of long-term use of the earplug so you can wear it for a long time without worrying about the usual fatigue issues. 【Reliable Customer Service】We have a professional team that always strives to ensure you have complete satisfaction.
