BE Sport4 Graphene Hi-Res Sports Bluetooth Earphones
Graphene Features
Graphene is so far the world’s thinnest and hardest nano-material (1nm= 10-9m) with the lowest impedance. The thickness of 200,000 graphene membranes equals that of one piece of hair.
At the same area (1m²)
- Graphene weighs 1,000 times lighter than a piece of paper
- 200 times harder than steel
- 10 times better conductivity than copper
Run along with the rhythm while listening to high-end sound.
6mm Graphene Driver Diaphragm
Compared to traditional driver diaphragms which require more power to drive, graphene diaphragm with a lighter weight can return to the original position more quickly for designer to nearly omit its need for energy consumption.
AAC/aptX Decoding
With either the iOS or Android platform, BE Sport4 supports Hi-Res decoding.
