2Drumtek erpi, is a well-known domestic brand Shuangfeiyan specializing in the development and production of headphone products sub-brand, through the improvement and optimization of the traditional dynamic structure, created a unique "two skin" diaphragm technology. Erpi cleverly uses composite materials to create a dual-material diaphragm unit, which brings better sound quality performance to users. Recently, Shuangfeiyan Erpi launched the B90 true wireless Bluetooth headset, equipped with a dual-material diaphragm unit, supporting the active noise reduction function, and then follow the author to see how this headset performs.
However, before officially introducing this headset, let's first take a look at what its main "two-skin" diaphragm technology is!
(Didermal diaphragm)
The "two-skin" diaphragm technology is to reduce the distortion performance of the three-frequency through the improved treatment of the diaphragm of the headphone unit, and bring users a more realistic listening experience. The two-skin headphone diaphragm unit uses a special material of carbon fiber hyphae imported from Japan in the mid-to-high part, mixed with special conifer pulp, and refined by using innovative papermaking technology. Compared with the traditional PET plastic monodermal diaphragm, the sound diffusion is better, which can reduce echo interference, make the sound performance more clear and natural, reduce distortion, enhance the three-frequency layering, make the sound performance more spatial, and the detail performance is also very in place, more durable.
(Dipixel diaphragm and PE plastic monodermal diaphragm)
We generally use bluetooth small headphones for plastic single skin diaphragm, because its surface is too smooth, so in the narrow ear canal is more likely to produce reflective echo, so that the music we hear, songs, or game sound effects are susceptible to echo interference, resulting in a muddy sense of hearing, over time it is easy to produce fatigue and irritability. The diaphragm used by the Double Feiyan Erpi True Wireless Bluetooth Headset B90 is a di-skin diaphragm, which has a rough feeling similar to a paper surface, and this rough feeling is a bumpy honeycomb mesh design, just like the uneven design on the wall of the concert hall, which can effectively reduce the echo generated in the ear canal, so that the user can hear more sound details and more comfortable and pleasant original sound.
