Graphene headphones: no need to tune the industry big name

Graphene has become a star in the material industry almost overnight, and it is considered by researchers to be the most promising new material in the future. Now, researchers have made a headphone using a graphene diaphragm, and the experimental results are amazing. The sound quality can easily kill the big earplugs in the market without any tuning. According to reports, the researchers placed a 7mm diameter graphene diaphragm between the two electrodes, because the graphene itself is super strong. The conductivity, so accurate control of current intensity can achieve excellent sound quality.

From the response test, the graphene diaphragm performed very smoothly in the range of treble 20Hz and bass 20KHz, while the rival Shen Haiser MX 400 performed slightly lower.

Finally, once again, the graphene diaphragm of this test has not undergone any post-tuning.
