After evaluating the DDHiFi TC19BC Comet Gold, I can state that this USB cable represents a clear evolution of the original TC19BC Comet (OG). The Comet Gold not only improves the sound but also addresses the lack of midrange presence in the Comet OG. In addition, this new version is five centimeters longer than the […]

The Kawano Sho is a flathead earbud that fits in the ears similarly to the EarPods that Apple sold with certain iPods.

The Sennheiser HD660S2 was a pleasant surprise compared to other models from the brand with which I have had experience, such as the HD600, the HD650, and the HD6XX.

Below, I present the reasons why I appreciated the HS110SE so much. […]
