The neckband features a fixed neck brace instead of a freely dangling neck strap. The brace rests lightly yet stably on your neck, providing comfortable support for hours. When not in use, the earbuds can be easily connected together thanks to integrated magnets. Perfect hold is ensured by the additional neck brace. By separating the battery and Bluetooth unit, weight is balanced for pleasant wearing comfort. It allows the headset to connect to two smartphones simultaneously. With the built-in microphone, you can easily switch between music playback and answering calls, ensuring you never miss a call while listening to music. The integrated volume control lets you conveniently adjust the volume via the cable. With the built-in remote, you can answer and end calls, activate voice control, and manage your music individually: Play/Pause/Next track/Previous track (if supported by the phone). With these earbuds and their sweat-resistant materials, you can really push yourself to your favorite music. The excellent fit reduces unwanted outside noise, allowing you to enjoy your music without interruption. The flat cable prevents tangling. The silicone ear cushions come in three different sizes (S, M, L) for a personalized, perfect fit.
