I'm just about finished with the 'daily use' testing.
This means me using it on the go like it was an iPod using very muffled $60 portable headphones with massive EQ. This was mainly for daily use functions, UI, how easy it was to function, and throw around etc.
True sonic listening started today and only happened for a bit.
But I did notice a very very slight lack of smoothness in the mids. While my Project-H and C4 Pro were able to handle difficult mid parts without much mid flucuation, the X5 had a bit of slight spikes (very hard to even tell) in the vocals during intricate times.
This could be taken to be the slight 'brightness' possibly. I didn't read Micey's post in detail so I don't know what his comparison equipment would be. Obviously, comparing the X5 to say an HTC phone output would leave the X5 brighter in some aspects. But I trust that he knows what he is doing.
But yeah, I currently spent a bit of time demoing a few songs and I do hear what I believe to be a slight combo of what Micey and I are referring to. In where a few portions of the mids have an extremely slight off balance flucuation. The X5 has a slight flucuation at the end of the mid vocal range making it have a very slight brighter end.
Basically, the X5 struggles with the mid end, and doesn't do it flawlessly.
In the end, I will half agree with Micey in that there is a slight 'spike' at the end of the mid range (leading into the highs), but in that it doesn't really make the sonic signature of the X5 bright. But rather is a sonic anomaly.
Here is a sneak peak link of the C4 Review which includes an X5 comparison:
I'll be doing some formatting, additional editing, and adding pics to make it a final official review tomorrow or Monday.
FiiO X5 with Colorfly C4 Pro
The FiiO X5 boasts a slightly warmer sound with a darker background than the C4. The frequency ranges are not as split and separated as the C4 is. This isn’t bad as it leads to a more cohesive and ‘consumer’ sound with the X5. The bass on the X5 are also a bit more pronounced, warmer and with more mid punch compared to the C4, but the C4 wins in the quality of the bass. Lastly, the mids on the X5 take a loss in smoothness as the C4 is able to power through challenging areas without any fluctuations in the mids. The C4 also promotes a cleaner mid range with a relatively ‘open’ background around the mid range. The X5 is more of a fun unit than the C4 at a cost of quality, while the C4 boasts quality, but at a loss of punch in its sound.
Overall, the C4, while it excels in almost every way from an audiophile standpoint, is a different device than the X5. The sonic differences between the C4 and X5 were very slight however. Lastly, the neutral sonic signatures are very close in their nature, to the point where I had to isolate certain sections of songs and test albums to get the results I wanted.
P.S Sorry for the poor writting skill in this post. This is not an example of my abilities. I've been up all day, and it's almost 3am.
