Headphones 4smarts 541401
The 4smarts 541401 open-ear headphones combine clear audio output with situational awareness, offering music and call handling without covering the ear. Open-ear speakers deliver powerful sound while leaving the ear canal free, and touch controls let you manage playback, answer calls and activate a voice assistant. Self-tinting lenses integrated into the frame automatically adapt to changing light and provide UV protection, while an IP65 rating ensures resistance to rain, dust and sweat. Weighing approximately 34 g and powered by a 200 mAh Lithium Polymer battery, these lightweight headphones are designed for active outdoor use.
Open-ear technology provides clear audio without isolating the user from the environment, allowing safe outdoor activity. Self-tinting lenses adapt to varied light conditions and reduce glare while offering UV protection. IP65 weatherproofing protects against water jets and dust, making the device suitable for training and outdoor sports. The ultralight design and ergonomic fit minimize pressure and slipping, and integrated touch controls offer convenient hands-free operation.
Place the open-ear headphones on your head so the speakers sit close to, but not inside, your ear canals. Use the touch controls on the frame to play or pause music, skip tracks, answer or end calls, and activate your voice assistant. The self-tinting lenses adapt automatically to light changes; no manual lens adjustments are required. Charge the device using the included USB Type-A cable until the battery is full; typical runtime is up to 4 hours depending on volume and usage.
For safe outdoor use, keep volume at a level that allows you to hear surrounding traffic and ambient sounds. After exposure to heavy rain or mud, wipe the frame and lenses clean and allow the product to dry before charging. Do not submerge the headphones in water despite the IP65 rating.
