final A4000 Single High Precision Dynamic Driver IEM Earphones With Detachable Cable

Product Information

The eartips provided enjoy so much popularity, I need not to expand on them. Great material, does not make your ear sweat exceedingly like an S&S will, no pressure buildup in the ear canal (compared to foams, or again the S&S for that matter), tonality wise it of course matches perfectly with the A4000. I don't like them so much on other IEMs, but that's outside the topic of this review. For the price, some of the detail here is absolutely breathtaking. It presents a crisp and airy presentation with articulate transparency and a dash of warmth. Certain elements like strings and acoustic guitars appear polished and clean, while vocals exude the best qualities of the entire timbre. Every vocal I listened to felt like it always sat in the right place, floating well above the rest of the sounds with an almost extreme level of clarity. SOUND IMAGING is great. Thanks to this transparency of timbre, we can dig and travel in the layers of sound as well as clearly discern the static location of the instruments. Next, if you go from 300 Hz up to 1000 kHz, this is known as the Lower Midrange, and this is a crucial region for

It's made out of plastic, but you could be fooled into thinking it's aluminum. It's a very high quality plastic, and build quality feels impeccable. The IEMs are quite light and small enough that there's no discomfort putting them into your ears. I bought VR3000 and liked it, so then I bought A3000, A4000 and A5000 to compare, I’ve had them all for about 2 months or so, just a Hobbyist reviewer, so please take it with a grain of salt, also my English might not be perfect, sorry. what are the pair of IEMs or Headphones that get a lot of shit from the community and the reviewers BUT it is a decent pair if not not good when EQed properly? mine are these Now I felt like the A8000 was already rather peaky to begin with, but the A4000 takes it to a different level. Now the A4000 isn’t peaky per se but it is certainly quite a bit brighter than the A8000. And of course the technical performance are worlds apart, so just like with the A3000 one shouldn’t expect the A4000 to be the mythical “mini-A8000”. Though in this case, “A8000/2” seems like a more appropriate epiphet. The impedance of A4000 is 18 ohm. Although the sensitivity is only 100 db/mW. Therefore it requires a little bit more power to drive the A4000 compared to the IE80 (16 ohm, 125 db/mW).The TONALITY is vivid, detailed, clear and precise, not neutral because it has a small rise in the bass and high mids, rather a well-balanced W curve. One could say analytical too, but not cold or artificial. It is less well balanced than the A8000, but extremely cohesive and even hyper-realistic. Despite amplified bass, there is almost no bleed. In fact, the A4000 surprises ad infinitum, due to a stunning versatility that surely comes from this little bass boost.

Almost clinical and perfect in their sound reproduction at the cost of losing some musicality and sounding sterile at times Summary: Departing from the common V-shaped consumer sound, the A4K provides the listener with enough vibrancy to be engaging but is still V-shaped. Just not a much so as others, who add more “oomph” up top. But in a smoother than normal manner. Bass could reach deeper for me as could its impact. That can be accommodated by EQing the sound. Mids are good but not great. I consider that part of the smooth nature. Male vocals are good and there is good clarity of note with both male and female vocals as well as the overall signature. I would not call it spacious but engaging again adding to that smooth sound to me. Upper mids are pushed forward, which seems to be the flavor de rigor, but not as much as others. With a fast decay, the notes heard are true and aid in that vibrancy of which I speak, but again to me the overall is of a smooth nature; especially when compared to the others here. I have now taken a look at both the new Final Audio A3000 and A4000 earphones, and written about them individually. In the coming weeks post the launch of these IEMs, it won’t be out of the ordinary to hear which one is superior for a multitude of people who’ve listened to both. Because of their simultaneous release, these new A-series models will always be thought of together and will be constantly compared to one another. So now it’s time to finally come to a verdict on which earphone better fit my taste, and how it might fit yours in soundstage, timbre, and comfortability. The PET, as diaphragm material, is quite light; this means that it has lower inertia and it can therefore move precisely according to the electric signal it is fed with. However, the diaphragm is always attached to the voice coil. If the diaphragm is light, but the voice coil is heavy, the overall movement of the two, which move as one piece, would be slowed down. For f-CORE DU, Final is using a 30μ diameter Copper-clad Aluminum Wire (CCAW) instead of the commonly used copper wire. CCAW is made from aluminum inside with a copper coating (copper cladding) outside. The density of copper is three times that of aluminum, so a CCAW voice coil is almost three times lighter than a copper voice coil, and as a result of this the couple diaphragm-voice coil has a really fast and accurate reaction to the feeding electric signal. On the other hand, thinner wire, like CCAW, means more turnsin the same space, so higher impedance, and therefore more powerful amplification is needed to drive the IEM, but the sound is definitely more accurate. This is the case with f-CORE DU. I found this image about the GOXLR DAC but I don’t know if this is detailed enough to know whether or not it will allow the A4000 to shine. I’ve heard the ES100 doesn’t do them justice, and I can’t imagine the GOXLRs DAC will be much better.

All the above made clear that Beryllium was not an option for the driver of A4000 and A3000. So, what was the solution? Final engineers had the idea to start from a humble and underestimated material, such as PET (Polyethylene terephthalate), which many manufacturers use, but in this case Final engineers tried to get the most out of it! How do you do that? By making changes to the voice coil, magnet and housing. The idea behind it is that if we want a driver to have a performance as close to perfect as possible, then all its parts must work as a single unit; if one (or more) of the driver parts has a flaw, then the driver ecosystem as a whole suffers. With how boosted the 4-10k region is, the treble is the star of the A4000. It’s not peaky, energetic, vibrant. Some may say it even has hot treble, which I agree. Bad recording can be easily spotted because of this. Microdetails are slightly above average. Intruments like cymbal strikes and hi hats are very forward, yet it doesn’t linger around as much, making it loosing that shimmering characteristics that I know of. Unboxing : I really, really like final's approach to boxing. The stuff is simple, but much sturdier than the chi-fi stuff I get to review. The years of experience really do stand out. Innovative systems for identifying right vs left channels isn't as effective as traditional methods Their musicality remains quite serious and mature, but never boring: they are iem's that wake up with their alert rendering, always focus.

The sound signature of the A4000 can be summarized as clean, natural, airy, and non-fatiguing. Upon the first listen I was immediately impressed by the clarity and how open the soundstage is. There are good extensions in both bass and treble regions. I can feel the bass rumbles if it was present in the music recording. I remember some frequency response charts showing that there is a small peak in the 2-4 KHz area. That might have something to do with the improved clarity. It also made A4000 sounded like some high quality BA drivers. The mid-range also sounded smooth and balanced, it’s not forward or recessed. Although sometimes the male vocals may sound a little thin. Imaging and separation are both decent and on par with the IE80 and FX750. I knew that Final intended to create a whole new A series of IEMs, and obviously the new series would contain higher as well as lower priced models. So, two things were going around my mind: silicon type eartips (SS,S,M,L,LL), each having a soft part for a comfortable fit in the user’s ear drum and a more rigid and groovy part for the sound conduit. This combination ensures a high level of sound insulation. SPATIALITY is holographic, circular, at the same time wide, high and deep but not in an extreme way, it remains a little intimate as if we were in a bubble with loudspeakers on all sides.Some might say U shape, some might even V shape, for me it’s more like a W shape (even with slight recessed mids I think they are in a nice level still), slight priority to the sub-bass.
