he black/red HD 1 In-Ear Headphones for Samsung Galaxy and Android Devices from Sennheiser are the smallest member of the HD 1 product family and offer a clear and powerful sound. They can be utilized to listen to music and take calls for Samsung Galaxy and Android devices. Featuring a wealth of details like the nano-precise, stainless-steel sound tunnel, and a three-button multifunction remote with integrated microphone, the headphones deliver high-quality sound in a small package. They are built with quality materials; the acoustic components contain no plastic. The earbuds feature an ergonomic, adjustable angle of 15°, and the headphones come with four ear-adapter tips (XS, S, M, and L) and a hard carrying case. Detailed Design and Comfortable Fit Over 200 contrasting red stitches grace the black-lacquered zipper on the soft-covered case that safely protects your earbuds. The headphone cable leads to a high-gloss housing, and the design details extend to the fit of the earbuds, which feature comfortable tips for a secure fit. Bright and Powerful The HD 1 in-ears combine durable materials with quality craftsmanship. The acoustic components contain no plastic—they are made of high-quality stainless steel, manufactured using precision milling technology. It's not a difference you can see, but one you'll hear. Adaptable and Ergonomic You can forget about the HD 1 headphones. With their ergonomic, adjustable angle of 15°, the buds adapt well to your ears. Thanks to the extra-small sound tunnel and a choice of four ear sleeves to fit most ear sizes, all you'll experience is pure sound. Functional and Durable The range of in-ear accessories is as broad as the in-ear itself, including a sturdy hardshell case, an intuitive remote for iPhones, Androids, and other devices (depending on the model you purchase), an elliptical cable that minimizes tangling and sound loss, a gold-plated jack, and an integrated hands-free microphone.
