The issue going on with the HiFiMan RE800 basically goes like this :
I joined Head-Fi several months ago after an audio enthusiast friend of mine recommended this site to me for doing research into audio and available iem earphones hoping to find one that matches my preference. However, I didn't post until recently, when after many months of reading, learning, and ultimately finding out what my preferred sound signature is, that I searched though dozens, maybe even hundreds of audio frequency response graphs, usually finding either three type of common dynamic driver measurements.,when suddenly I found a rare alternative measurement posted by Head-Fi moderator, Brooko, of the HiFiMan RE800.
The common measurement types I've seen of Dynamic Driver iem earphones, are u or v shaped, the downward sloping ones with lots of bass, and the neutral bass and mid variety that slope way down in treble. Whereas, the HiFiMan RE800 actually is quite different and much more closely resembles my preference where the bass and mids are mostly neutral , but the treble rises above both, rather than sinks. This at least according to Brooko's graph. Although as his profile shows him to be in New Zealand, in the Asia Pacific area, its possible his has different tuning.
He and some others have mentioned hearing a treble spike, which his graph shows, but I've listened to cymbals on it several times, yet I cannot hear any treble spike with the cymbals actually sounding weak to me, whereas the vocals just are not present enough, being recessed a bit by the bass, though not in any major way.
Still, I suspect there is a different tuning being sold to customers in the U.S. where I'm in. Unless I got an updated tuning model ff global retail. While I doubt this is happening with the FlaresPro, I'm wondering what may be different with the FlaresPro he reviewed in contrast with what others have been saying about it .
