So let me say this off the back, to my ears these aren't lacking bass at all. There is plenty of visceral bass (including sub-bass) if it's in your recording. I would say there's more and deeper bass than in my beloved ME.1 (which you can pull some good bass out of that planar with the right fit), but if you're looking for a "basshead" earphone, this is not what you're looking for. the sound is more balanced. Here's the thing, there are four types (or sets) of ear tips in the beautiful packaging. One says "balanced ear tips" and another one says "vocals ear tips". I noticed that those two sets have narrow openings. The bass ear tips set have a wider tip opening. I didn't try any of them yet. No, I went straight to one of my good and reliable tips (the wide bore UE900 silicone tips ... the other one is my JVC Spiral Dots). The bass is pouring out with these tips! No issues with bass (I'm listening to the Lenny Kravitz Are You Gonna Go My Way album.
The other early observation about this earphone with initial impressions is that it's tuned more as an in-ear monitor than just a fun earphone. What does that mean? Well, to me that mean that the soundstage puts your closer to the stage and musicians. It almost like you're in the front row or in the studio with the musicians. So the sound is forward, but it's not an annoying forwardness. And I certainly don't hear the vocals as being pushed annoying more forward than the rest of the instruments. The instrument separation in this iem is spectacular!!! Even with the deep bass, this iem clearly focus on the mids and vocals with lots of transparency and clarity. For me, I need to burn it in to see how much the bass will change, but I have to say that I recommend right off that back that new buyers tip roll. I think sometimes we forget how much tips can shape the sound of an earphone.
On first listen does this iem punch above its $250 something price point? Heck yes! Without a doubt, Fiio has a winner here (I bought these with my own money, so no one can claim I'm in Fiio's pocket, and I would no doubt tell you if I hate them). I don't have the LZ A5s with me, but I don't need it to tell you that the FH5 surpasses it in clarity and resolution (and I'm very hyped on the LZ A5).
I do, however, have the AKG N5005 with me. Does the FH5 equal or surpass the N5005? LOL... I know some of you want that answer (and hope that it can surpass the AKG TOTL). Okay, if I'm going to be honest (and I am always that), no, the FH5 doesn't surpass the N5005 at this point. The AKG has a clarity and digs down to pull up micro details like very few other earphones I've heard that didn't have too harsh of highs (and it's bordering on that harshness without going there). Plus, the N5005 has some of the best clean deep bass I've heard in an earphone. But..... the FH5 is not super far behind the N5005. It sounds very good (great for the price). It pulls out details too that you don't find in most iems at this price range. Kudos to Fiio for a fantastic job! Now let me get to burning it in to see what all it will reveal to me. I had to write fast as I'm on break and wanted to give the community some initial impressions. I'll come back and clean up in editing later. Happy listening!
