Over the years, the X7 has become the device Fiio intended it to be through numerous software updates and fixes with that same terrific sound underpinning the entire experience. The X7 achieves great ergonomics through its very smartphone-like form factor and great versatility through a modular design. While its hardware is hardly cutting edge in comparison to the latest and greatest smartphones on the market, the X7 nonetheless provides a convincing user experience through the adoption of the feature rich Android user interface. Luckily, these added features don’t come at the cost of sound quality and the X7 demonstrates that a lot of buyers could benefit by looking into older technology designed to a higher standard than newer models. The newer X5 III is a slightly more musical source and one that I would enjoy in isolation, though I found better synergy with the X7 on the majority of my gear due to its greater neutrality and linearity. The X7 provides a smoother, more organic take on the highly resolving Saber sound that proves to be highly rewarding in terms of both resolution and long-term listenability.
Verdict – 9/10, The X7 is aged but by no means long in the tooth. The X7 has a nice display, a fluid user interface and well-considered ergonomics. Its sound combines resolution, clarity and refinement and the ability to swap amp modules provides some basic sound adjustments and varied output power for a wider range of headphones.
