Here's a review of the Fiio FA19: https://www.head-fi.org/showcase/fiio-fa19.27212/reviews#review-33796
This is a 10 Knowles BA set, which has a vented sub-woofer, so it sounds close to a DD bass instead of the traditional BA bass that lacks movement of air and decay.
Pros:
Bountiful accessories
Modular cable for both single-ended and balanced sources
Solid build
Ergonomic and light; no pressure sensation in the ears due to vented housing
Easy to drive, amplification not needed
Tuning switches for versatility - warm neutral in stock tuning, with option for bass boost
Excellent technicalities - soundstage and imaging are a highlight
Bass sounds like a DD bass due to vented sub-woofer concept; fast, clean and textured basslines
Transparent midrange that is free of shout
Smooth yet resolving treble, without steroid boosted high frequencies
Cons:
MMCX
Average isolation for an all BA set
Low impedance - source pairing potentially tricky with high output impedance sources
8 kHz is a coupler artefact peak on the IEC711 coupler.
