The True Wireless sleek design and interchangeable 3D Loop Support provide a discreet yet secure in-ear fit. The newly improved ear tip design has better passive isolation and wearing comfort. The housing has been developed to fit a variety of ear sizes with silicone ear tips which allows it to stay in, limiting falls. The increased flexibility of the ear tips provides additional ergonomic comfort. The newly designed 10mm dual-layered diaphragm drivers deliver solid bass high definition sound. The ATH-CKS5TW will have 15 hours battery life on its own, and another 30 hours from the charging case, bringing its total usage time to 45 hours. The headphones come in 3 different colours: Classic Black (BK), Unique, Elegant Blue (BL) and Refined, Polished Khaki (KH)
