Pico Entertainment is a company specializing in the development of portable audio products. It has launched two brands: Pico Audio (focused on the development of portable headphone amplifiers) and Rolling Force (focused on the development of headphone cables).

​

As a brother brand of Pico Audio, Rolling Force has a different product focus. The huge difference is the product development targets. Rolling Force mainly develops more end-user products, entering the market with more affordable prices and high-quality products.
 

In 2022, after we announced the success of the highly acclaimed silver-plated flagship line Mercury, many users asked if we would launch a line made of sterling silver and we all said that there is no relevant plan. At that time, it wasn’t that we didn’t want to launch sterling silver cables, but the sound of the samples didn’t meet our pursuit of sterling silver cables, and it would only be an ordinary product if we forced it out. By chance, we found a Type 6 (actually that is Type 4S+ specially made by the factory) silver-white wire when sorting out the samples from the factory. At that time, we did not test further due to various factors, so we confirmed with the factory again. Only later did I realize that the wire was made of monocrystalline silver. Finally, today in 2023, after countless tunings, we have made what we think is a pure silver wire - Diamond.
