The FD11 from FiiO is a solid budget release. It boasts a vibrant sound signature. The treble is well controlled, avoiding any sibilance or harshness that can be fatiguing over time. The bass is deep and snappy, delivering a satisfying punch. Additionally, the FD11 exhibits decent resolution and imaging. However, it is important to note the possibility of fit and seal issues. The fit and seal are my only concern about FD11, as beginners and casual listeners would not have a drawer of ear tips to try to mitigate the problem, should they fail to achieve a good seal. And without a good seal, FD11 sounds thin and harsh with very little bass.
In terms of target audience, I think FD11 is suitable for casual listeners who prioritize affordability and a good sound experience without getting too caught up in the concepts of “scaling” and “synergy” that often come with higher-end equipment. FD11 also serves as an excellent entry point for beginner head-fiers who are exploring the world of IEM.
Pros:
- Vibrant sound signature
- Well controlled treble that is not sibilant or harsh
- Deep and snappy bass
- Decent resolution and imaging
Cons:
- Potential fit and seal problem
