Fiio Q15's Review - Versatile and Musical

Having tested and used the Q15 for quite some time prior to publishing this review, Q15 definitely has what it takes to make the statement in the fast moving market with various competition. Q15 is a very versatile product and I find the use case is very suitable for portable users and also headphone users that don't use overly power hungry headphones.
The power output is definitely sufficient for most IEMs out there and also headphones that aren’t overly power hungry (Tested with the headphones which I owned, Hifiman Sundara Open Back, Hifiman Edition XS, Hifiman Sundara Closed Back, as well as Aune AR5000). In terms of sound, it is definitely not neutral yet the coloration is somewhere in between and quite balanced overall, which I personally enjoyed and find it rather easy to pair with most transducers. The only gripe that i have with it is the size, if only it has a slimmer and shorter profile, then it is definitely an undisputed portable power house, however, it is also understandable that packing so much tech and features into the Q15, there are definitely some limit in terms of the size. All in all, if you enjoy a dynamic sound yet you don’t like an overly colored signature, Q15 is definitely highly recommended!
