The black HD 1 In-Ear Wireless Neckband Headphones from Sennheiser feature a combination of ergonomic design, good sound performance, and take-anywhere mobility in a Bluetooth 4.1, Qualcomm aptX headphone. With NFC for simple one-touch pairing, an integrated microphone, and a ten-hour battery, the headphones can be used to listen to music and take phone calls with mobile devices such as smartphones, tablets, and MP3 players.
The neckband of the headphones contains a three-button remote and a high-quality microphone. It also supports multi-connection for up to 2 devices at once. Voice prompts notify you of the pairing status and provide battery-life warnings. Additionally, there is a vibration alert for incoming calls. A USB charging cable, four pairs of ear adapters (XS, S, M, L), and a carrying case are also included.
