FiiO FH7Schat_bubble_outlineFrom real comments

Soundstage and treble are the FH7S's strongest traits. Commenters repeatedly highlight the FH7S's wide, precise soundstage and 'Sennheiser-like' treble presentation that avoids harshness or sibilance. One listener compared it favorably against IE600, FD5, and FH9 after extensive A/B testing in-store, choosing FH7S for its surround feel. Others note it offers more air and natural instrument timbre than the original FH7, though isolation suffers due to the semi-open build, which worries commuters.

Bass is warm and fun but can feel bloated without adjustment. Multiple users describe thumpy, bloated mid-bass out of the box that improves significantly with break-in (up to 200 hours) and tip swaps like Spinfit or AZLA SednaEarfit. The bass suits genres like 70s/80s rock, dancehall, jungle, and drum & bass well, injecting fun into otherwise thin mixes. However, some feel it lacks neutrality unless EQ'd, and one long-term owner found only the bass nozzle configuration truly satisfying across genres.

Comparisons to FH9 and FH5S are mostly favorable to the FH7S. Several commenters explicitly prefer the FH7S's tonality and fatigue-free listening over the FH9, citing better balance despite the FH9 leaning more sub-bass focused. Others say the FH7S markedly improves on the FH5S's thin mids and shrill treble. A few miss the original FH7's design and stronger bass punch or isolation, and some feel FiiO's tuning hasn't kept pace with newer competing chi-fi brands at the same price point.
