FiiO EM5 got here, initial impressions are. Drums sound like drums. Full, dynamic, thumpy, fast, slammin. I would say there's actual subbass extension and rumble, midbass feels clean and natural, although I do feel an overall sense of 'body' to the music. Unfortunately everything else sounds a bit distant, if not muffled. By comparison Chaconne have a bell-like clarity for female vocals and, well, bells, etc. The FiiO EM5 overall feel "thick" and "laid back", bordering on "dark" or veiled. Female vocals feel a bit hollow or thin, maaaybe even rough/sharp, and feel like they're behind me and to either side of me. The presentation isn't as intimate, emotional and forward as the other buds I have, but I guess those are more upper mid/treble-strong (EBX21, Chaconne, ME80).
I'm swapping between Chaconne and EM5 right now and the Chaconne is definitely more 'open' feeling, airy, sparkly. The EM5 by contrast feels dummy thicc, almost muffled. Like going from a concert hall (Chaconne) to a club or warehouse party (EM5). Maybe some burn in (ie: 300 hours lmao) is necessary to open these up as well. As for tips, I'm using Chaconne with a silicone ring and then a single full foam over it, with EM5 I'm just using a single full foam (same as the Chaconne one, not the provided FiiO one since I might return these.)
The fit on the EM5, by the way, is maybe the best I've tried. I have no idea how it's possible, but it's super light and just.. goes in and sits where I put it. I can wear it cables down and turn my head and all that and it's fine. I don't need to readjust it like I do with the hefty Chaconne. The cable is really good too. FRICK. The more I type the more they're growing on me.
I want to say they're a "fun," "musical," "laid back," and "non-fatiguing" (in every sense of the word) bud. I'm still experimenting but they sound pretty good with some EQ upping at around 2K, which leads me to believe my next thing to try should be donut foams to open up the higher range a bit.
FiiO EM5 in a word: FULL
Moondrop Chaconne in a word: 𝒸 𝓁 𝑒 𝒶 𝓇
So, those are initial impressions. I will read some actual reviews from people who know what they're talking about, and then see if my impressions are anywhere in the ballpark.
