fiio jm21 review ProsCons...
The FiiO JM21 promotes itself as a musical DAP first and foremost. The sound comes across as musical and clear. The typical FiiO crispness to the signature allows the sound to showcase what you hear. When used singularly for music or streaming, it competes with its peers very well.
Pros
- Very good detail retrieval.
- USB streaming functionality is an excellent addition.
- Single-ended and balanced Lineout.
Cons
- Thin case may not protect the JM21, especially that thin bar.
- FiiO music app is not intuitive, nor as inclusive as other brands.
