The design of the f-Core for 8K SOUND had also to take into account the basic requirements necessary for implementing DSP. It is well-known that one of the biggest challenges in creating a driver is the manufacturing consistency between driver units. Generally, slight disparity during production, known as “production variance”, is unavoidable, and therefore it is a common practice between manufacturers to accept a certain range of production tolerance. Now, for drivers intended to work in collaboration with DSP, it is critical that these manufacturing tolerances to be as low as possible. For example, if the adjustments made through the FIR filter are smaller than the production tolerance, then these adjustments would be ineffective, and the output would not be as expected or could even be worse than that, causing a negative impact on sound quality. Having said the above, one would easily understand that I waited eagerly the arrival of the flagship ZE8000. Before I go on, I will cut it short and say that ZE8000’s performance is nothing that I have heard before, by either an IEM or a TWS system. What make me say that? The fact that the sound is: The IPX4 rating means that the ZE8000 are secure from minor splashes and water sprays, but there is no dust protection. Software A good footrest is as important to comfort as the chair you sit in, and Secretlab’s Professional Footrest is ideal for home or office use There is no treble peak whatsoever, and it’s a flat line until 10kHz, which is highly unusual for IEMs. However, the upper-treble extension is excellent, as the ZE8000 showcase some response around 17kHz.
Review: Final ZE8000 - Mixed Feelings - Headphonesty
Let me start by saying that the biggest advantage of Bluetooth headphones and earphones, over the conventional wired headphones and IEMs, is that in the former has everything in one shell: The DAC (Digital-to-Analog Converter), the amplifier system, the computing unit, the power source and the drivers, all are crafted into a single unit. This gives a big advantage in perfecting sound quality, from the sound source signal input all the way up to the sound wave output. Well, not really, the naming could be misleading a bit. It’s called 8000 not because it’s a wireless version of the A8000, but rather because it’s a flagship of this series, which makes sense. We were big fans of the Final UX3000 over-ear headphones last year, giving it 4.5 stars in our review and awarding it Best Affordable Headphones 2022 at our end of year awards. Vocals quality stands out the most - they are perfect, with most lifelike timbre and air - never heard anything like this.The ZE8000 app includes the Volume Step Optimizer which allows you to increase or decrease volume in smaller decibel steps than is usually set on your smartphone’s volume control. However, most of my reviewing was done using an Astell and Kern SE180/SEM1/SEM4 DAP which works much smaller than 1dB steps. However, using this app on my Sony Xperia phone was a godsend. Final’s first TWS IEMs in the ZE series, the ZE3000, garnered widespread praise and are still among the best TWS IEMs I have experienced. Final has not given more details on DSP, as there is a patent pending. However, one thing is certain: All DSP’s computational power aims towards (only) one purpose, sound reproduction quality. As I pointed out, ZE8000 has a unique "balanced tonality"; it is unusual and not encountered in a wired IEM, simply because it cannot happen. It suffices to look at the frequency response graph to realize it. Final chose to do this and it can do it simply because it can control everything through DSP.

Instead, the ZE8000 require a degree of restraint. Gently inserting them, with a very slight twist — and stopping as soon as you meet some resistance — is the key. If things sound muffled, or the bass response feels thin, try switching eartips or placing the earbuds slightly shallower than you might normally think to do. Simon Cohen / Digital Trends Impressive performance The ZE8000 on the other hand is smoother, more delicate, and relaxing of the two. It does better with acoustic and jazz, while the Svanar Wireless sounds better with music that needs power and dynamics.The improvement wasn’t noticeable when using the ZE8000 earbuds outdoors or in a noisy environment. 8K Sound+ was a massive drain on the battery, so I ended up turning it off and never felt as though I needed it when listening indoors. The soundstage extends to all possible dimensions and the positioning of voices and various organs is almost perfect. The image is holographic and really fills the space, while the separation is excellent. For now, even though the ZE8000 has many quirks and small problems, I’m still going to recommend it to those who value the sound quality the most.

In addition to SBC and AAC codecs, ZE8000 supports the uninterrupted, high-quality Qualcomm® aptX™ and aptX™ Adaptive codecs for wireless transmission up to 24bit/96Hz, while it is compatible with Snapdragon Sound™. The touch controls on the ZE8000 work well, and despite the fact that only the portion of the bar that intersects with the body of the earbud is touch-sensitive, I had no problems getting taps to register accurately. You can’t change the gestures, but for the most part, they’re easy to remember and you get access to every feature, including volume control.
Wireless Performance
I think the above three is what makes Final saying that ZE8000’s performance is the “True Sound” of music. It is hard for me to describe how “true” is a sound coming out of an IEM, headphone or TWS system, as true is only what is played by the orchestra or found in the nature; however, for the first time I thought that maybe what we call “true” is as close to the actual true as possible. Inside the box, you’ll find the TWS IEMs themselves with the charging case, a set of silicone eartips, a cable for charging, and manuals. Next up, the 8k sound. I’ve tried, I really did, but I cannot hear even the slightest difference between it being turned on or off. For the sake of this review, I’m keeping it on, to ensure the highest quality (regardless if the difference actually exists or not). An interesting question is, how Final succeeded in making ZE8000 to be balanced, natural and clean in a way not found before? The answer to this is that ZE8000 is engineered to reproduce every single note in a musical piece with the highest possible timbre quality. And of course the next question that naturally comes to mind is, what is the single critical factor that allowed ZE8000 to have this unique timbre reproduction? There is no doubt that the first step towards this was the design of the new f-CORE for 8Κ SOUND driver, the use of a class AB Amplifier and Rubicon PML CAP capacitors and, most of all, the Proprietary DSP Algorithm and FIR Filter, which makes all the computational work. However, I believe that the single critical factor for the unique timbre reproduction is that all these components were designed to live in the same eco-system, and this make them to collaborate as close to perfect as possible. Battery life is another weakness. Final Audio claims five hours per charge for the buds, which is OK, but not great. It’s the case that really disappoints. Its large size wasn’t used to house a big battery: you can only recharge the ZE8000 twice, for a total of 15 hours of use before needing to plug it in. Keep in mind, 15 hours is an approximate number. If you listen at volumes louder than 50%, as I expect you will want to do, you may get as few as 13 hours total.

Really entertaining and very informative review. Very thorough and well written. I would however, like to point out that Bluetooth has been capable of audibly transparent implementation for far more than the last few years. I transitioned from wired in both my headphones and with my DACs, preferring to BT from my phone and skip the unnecessary computer via USB to DAC setup several years ago, and I never for a moment felt there was any difference in the sound reproduction fidelity from any audibility standpoint. Even humble AAC is highly capable. The EZ8000 IEMs come with their own charging case and a 5 minute charge will give you 45 minutes of listening SOUND QUALITY OF FINAL EZ8000 IEMS Significantly eliminates wind noise captured by the microphones when there is a lot of ambient air movement. In wired headphones and IEMs, engineers try to optimize sound performance by changing the headphones’s or the IEM’s physical properties (hardware), such as changing the shape and volume of the housing, controlling the rate of air pressure, implementing materials with different sonic characteristics, etc. However, once one of these properties is slightly changed, all the factors involved in the optimization process are influenced, too, with some becoming betterand others becoming worse. Therefore, it is almost impossible to achieve a completely perfect system with trying tooptimize all of these factors at the same time. This limitation is even more critical in a TWS system, where a micro-level change is rather significant.
Once they’re in position, there’s quite a lot to enjoy about the way the ZE8000's sound. Certainly from the top of the frequency range (which is bright, substantial and carries an awful lot of detail) down to the bottom of the midrange (which is equally information-rich, equally varied where texture and timbre are concerned, and equally convincing) they’re enjoyable and winningly naturalistic. Tonality is consistent, and the generous nature of the soundstage the ZE8000 create means even complex recordings are laid out well and easy to follow. Some people might find that the volume is a bit low. It actually isn’t, as the user’s ears have to be protected by setting the max volume level to adapt to the CE volume level specification. The Final ZE8000 support th The design and build quality of theFinal Audio ZE8000 are both very good. These are definitely on the bulky side, and they definitely protrude from your ears a lot. Forget about wearing this to your bed (if you’re a side sleeper), under a helmet, or even a snug-fitting hat. The Final Audio ZE8000 is a bag of mixed feelings for me. The sound quality and tuning are both great and highly attractive for audiophiles who have been waiting for true “audiophile-grade” TWS IEMs.
