Graphene Features

The driver diaphragm of the BE Free5 made of the rare graphene, which is considered as a magical material of future technology, realizes Hi-Res sound quality on independent true wireless earphones. Graphene is so far the world’s thinnest and hardest nano-materials (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

5.6mm graphene driver diaphragm for excellent high-end sound quality

Compared to traditional driver diaphragms which require more power to drive, graphene diaphragm with a way lighter weight can return to the original position more quickly for designer to nearly omit its need for energy consumption.

BE Free5

Support AAC

Enable high-quality sound on mobile iPhones and Android phones (8.0 and above).

(AAC support is discretionary as some 8.0 or above Android phones do not support AAC.)

Intensive Pre-launch Live Trial for 80.6% Fall-proof Guarantee

With big data analysis and study on the comfort and fall-proof, R&D engineers found that a 9.81° turn can best fit the human ear canal to prevent the earbuds from falling out. The result of the fall-proof trial on 100 persons around the world guarantees 80.6% fall-proof.

Activating Future Technology

The charging case has a space capsule design. By housing two earbuds in side, it looks like the seal of future technology coming from hundreds of thousands of light-years away. Inside this long and narrow space capsule, the BE Free5 is charging and standing by. As the hatch opens and being pull off the capsule, the BE Free5 is turned on and connects to the previously linked mobile phone automatically. By blending the sci-fi plot to the design, designers have condensed the charm of the BE Free5 at hand.
