Hey everyone! I just want to share my experience with the FA7 after listening to them for about 20 hours. In addition to that, I will also make a short comparison between the FA7 and my Audiofly AF180 ($500) since both of them are quad BA.
In terms of packaging, accessories, build quality and design - I am beyond impressed. These look and feel like an extremely well build IEMs. Comfort is amazing, although I find the cables a little too robust over my ears and they tend to weight a bit after listening for a couple of hours. The reason why I decided to purchase these is first - the amazing reviews regarding the FA7, and second - I wanted a quad BA that reproduces a little bit more bass than my AF180's. To my surprise, after the first two songs that I played on the FA7, right away I was able to notice the HUGE emphasis on bass these have. It is way more impactful than I initially expected. Which brings me to my next point - sound. Too much bass, to the point where vocals and details are being overshadowed by it. Some songs work nicely, others not so much. I would lie if I say that I didn't enjoy the bass at times, but it is way too overwhelming for my listening preference. Another issue in terms of sound that personally bothered me a little bit is the reproduction of vocals. I cannot really explain or understand where that comes from, or maybe I've been spoiled by the AF180's phenomenal sharp vocals, but the vocals on the FA7 sound a bit artificial to me. As if there is a filter placed in order to make them sound smooth and less fatiguing, specifically in the highs region.
Despite the cons I mentioned above, these are definitely capable of better and more balanced sound after some EQ. I don't know why FiiO decided to add so much bass impact on supposedly a more balanced IEMs. To me they lean more towards the mass bass lover consumers, rather than audiophiles or people who enjoy a more realistic and balanced listening experience. The FA7 can depict details and provide a good soundstage and imaging, but I feel like the bass ruins the joy most of the time and doesn't let FA7's true capabilities to shine. Considering the $300 price, the overall performance, build quality, comfort, and design, make the FA7 an amazing value for people who prefer more bass-heavy IEMs who can still reproduce a lot of detail, soundstage, and overall a decent sound. I might sound too critical about them, but in fact, I really enjoyed the FA7. Unfortunately, not to the extent where they would be able to replace my previous AF180.
Audiofly AF180 vs FiiO FA7
The difference between these two is night and day. Where the FA7 comes with more fun and overall bassy performance, the AF180 to me is the definition of an extremely well-balanced and realistic sound. Unlike the AF180, the FA7 is more on the dark side, with veiled vocals and too much warmth in general. The AF180 can point every little detail in a song and I can tell right away where is the position of each instrument in the recording. Also, the soundstage is OUTSTANDING on the AF180. Once I close my eyes and listen to them, I truly experience the sound as if I'm sitting in the room with the singer and the band while they perform. The soundstage on the FA7 is definitely noticeable on certain tracks, but not as wide as the AF180. And as I mentioned above, the difference in the vocals is pretty big for me. I have never heard before more accurate vocal reproduction such as the AF180 reproduce. It's marvelous. I cannot be 100% certain what a truly realistic vocal might sound like on an IEMs, but the AF180 make me believe what I listen, to be just as accurate as it is in the recording studio. Also there is ABSOLUTELY NO FATIGUE with the 180s. I don't find the FA7 fatiguing 97% of the time, but for example "Shallow by Lady Gaga and Bradly Cooper" did cause some fatiguing towards the end of the track. In terms of details, the FA7 produces just as many details as the AF180s, the only difference is that with the FA7 I had to listen carefully in order to pick up some of the details in the back, while with the AF180 doesn't let you lose any detail out of sight.
I only wish the bass impact on the AF180's was a tiny bit more enhanced, but I feel like the FA7 made me appreciate the clarity and the balanced sound on the AF180 even more, so I think I can live without some extra bass in return for a more realistic listening experience. And lastly, in FA7's advantage, they completely blow away the AF180 in terms of build quality. From the cables to the actual body of the IEM, I would feel way more confident in FA7's durability.
In the case of these two, the $200 price difference is well justified by the performance of the AF180's, at least for me personally, which by any means does not make the FA7 a bad value. In fact, it is an amazing alternative for some who prefer a more budget-friendly quad BA high-end IEM. But for now, I would have to return them and will wait for FiiO's next releases. And lastly, I would encourage anyone to try the FA7 by themselves. We all have different preferences when it comes to sound!
