The Belkin Soundform True Wireless In-Ear Headphones are perfect for enjoying audio during sports and lifestyle activities, thanks to their crystal-clear sound and exceptionally comfortable design. With ear tips available in three different sizes, they fit any ear and are also protected against sweat and splashes with an IPX5 rating. The in-ear headphones feature intuitive touch controls and can be easily connected to all Bluetooth-compatible smartphones. The battery provides up to five hours of uninterrupted playback, and with the convenient charging case, a maximum runtime of up to 24 hours is achievable. In-ear headphones are inserted directly into the ear canal, creating a pressure chamber effect that allows for a powerful sound experience without the need to turn up the volume too high. This is gentle on your ears and also extends the battery life of your playback device. Additionally, in-ear headphones have excellent noise-canceling properties, significantly reducing the perception of disruptive ambient sounds. Their compact size makes them easy to store in any pocket, making them the ideal companion for on-the-go use. The fully closed design of these headphones is not very breathable but offers powerful sound and rich bass. Furthermore, external noise is effectively dampened, and the isolation works both ways: outsiders can hardly hear your music.
