Purchased in July 2023. The box and instruction manual are not included, only the items shown in the photos. The ear tips have been replaced, so they are almost unused. I will do my best to ship as quickly as possible. Please refrain from price negotiations. The ATH-CKS50TW2 is a next-generation, heavy bass model that allows you to listen to music with earphones in the shortest and fastest way possible, and you can leave the charging case at home. It boasts an industry-leading long battery life, with up to 25 hours of continuous use. While maintaining the importance of the relationship between heavy bass and wearing comfort, it also employs hybrid digital noise-canceling technology that creates a personal space in an instant, providing an unprecedented sense of immersion wherever you are. It features a function that turns the power ON when you take the earphones out and separate them, and turns the power OFF when you attach them with magnets. This eliminates the stress of "worrying about the battery running out if you don't put them in the charging case" and "the hassle of taking them out of the case every time" that you may have felt with previous completely wireless earphones, allowing you to use them immediately when you want to. By combining the long battery life, which is a feature of this product, with this function, you can use the earphones all day long without carrying the charging case. In addition, the left and right earphones stick together, making them easy to carry without getting separated, making them extremely easy to use on a daily basis. (From the official website)
