This bluetooth earphone has been Improved to make a more comfortable shape and structure. Collecting data of over 1000 users has helped us to optimize the traditional mini-bluetooth-headset shape by shortening the horns, the length and the angle to the ear. This makes it more comfortable and safer to wear.
The In-Ear bluetooth headphone with noise reduction for best HD sound. The S540 can be used by people with large or small ears. It reduces in its size near the ear, so it fits even the smallest of ears without pain.
The bluetooth headset can be used purely by pressing the buttons on it -- you don\'t need to use your phone if already connected via bluetooth. In contrast to earlier versions, we have increased the button sensitivity by 50%.
The battery life has been increased by more efficient chip-technology in this new bluetooth earbud S540/S530plus. Thanks to the restructuring of not only the size but also the electrical consumption has been optimized.
With a new bluetooth-chip it strengthens and stabilizes the signal, even if your phone is a distance away. It can be used with 2 separate devices and connects automatically if it was the last interaction.
