Final Audio E4000 In Ear Isolating Earphones

Final Audio E4000 In Ear Isolating Earphones

 

The Final Audio E4000 In Ear Isolating Earphones offer a sound quality design rooted in the latest acoustic engineering and psychological research findings. With a focus on delivering clear sound quality across all bandwidths and a sense of real, true-to-life sound, these earphones are designed to provide an immersive audio experience. Unlike conventional sound creation methods that emphasise certain high frequencies, the E4000 takes a different approach, ensuring that no particular sound ranges are emphasised. This commitment to detailed sound expression results in a realistic soundstage that feels as if the music is being played right in front of you.

Moreover, the E4000 features an MMCX connector and comes with an original OFC cable, allowing for easy replacement in the event of cable breakage. The earphones also incorporate a unique swing-fitting earpiece mechanism, enabling them to be adjusted for a perfect fit. This mechanism prevents changes in shape and ensures clear sound transmission directly to the eardrum, delivering an exceptional listening experience.

The precision-engineered 6.4mmφ dynamic driver unit boasts extraordinary precision for its price range, enhancing overall sound quality. Additionally, the highly rigid machined aluminium housing provides firm support for the driver unit, suppressing unnecessary vibrations and contributing to classic sound quality. The earpieces themselves feature original designs with colour-coded bushes, making it easy to distinguish between left and right earpieces and different sizes.

Ear hooks included with the E4000 alleviate cable touch noise, reducing unpleasant rustling sounds that may occur during movement. This slim and comfortable design ensures a seamless listening experience, even during active use. The earphones come with a silicon carry case for easy storage and portability, allowing for convenient transportation while keeping the cables neatly organised and the earphones protected.

Finally, the E4000's sound quality may improve over time with regular use, as micro-signals move more freely within the driver unit. Aging, as it's referred to, is a phenomenon where sound changes with sustained use, ultimately enhancing delicacy and sound quality. This makes the E4000 a long-term investment for those seeking an evolving audio experience.

An acoustic chamber that is the core of low-frequency tuning

There is an acoustic resistor inside the rear housing of the driver unit, and this controls the low mid-range frequency characteristics that determine the framework of the sound quality. At the end of this, there is a pipe bent into an L-shape (acoustic chamber) which is necessary for tuning; with this, we have achieved a balance between the volume of low frequencies and clarity.

 

MMCX Connector＆Original OFC cable

The MMCX connector was developed in-company. Taking touch noise into consideration, soft, flexible coated material has been employed. When using ear hooks also, it moves flexibly, making for a good fit.

 

Unique swing-fitting earpiece mechanism

With their swing fit mechanism, the earpieces can be swung left and right and tilted towards the audio canal for a perfect fit. These prevent changes in shape owing to the aperture of the earpiece coming into contact with the audio canal. The sound is transmitted directly to the eardrum, delivering clear sound.

6.4mmφ dynamic driver unit

The precision involved in assembling the parts for the driver unit is of the utmost importance. The small-aperture 6.4mm diameter dynamic driver unit boasts an extraordinarily high level of precision for this price range.

 

Highly rigid machined aluminium housing

Compared to a plastic housing, this housing machined from aluminium with a alumite finish firmly supports the driver unit and suppresses unnecessary vibrations. Fitting of a device for the mature listener, this is a design that has a simple shape and a high-quality texture matched with what could be termed classic sound quality.

 

Original earpieces with a colour difference between the left and right bushes.

Two types of silicon differing in rigidity are employed for the sound conduit and for the earbud that comes into contact with the user’s ear. The silicon used for the sound conduit is more rigid than that used for the earbud, and by having groove processing applied to it, combines both strength and flexibility. Soft silicon has been employed for the earbud, making for a comfortable fit and a high level of sound insulation. One of the bushes is grey, while the other is red; by pulling the earpiece back slightly to check the colour of the bush, it is easy to distinguish between left and right, even in places with subdued lighting. Since the bush colours of neighbouring sizes are different (the grey bushes alternate between dark and light grey; the red bushes alternate between red and pink), it is also easy to distinguish between sizes.

Comes in 5 sizes – SS/S/M/L/LL

 

Ear hooks that alleviate cable touch noise

With similar existing products, it was assumed that they would be fitted to ears of differing sizes; not only were they large in size, their appearance was rather too distinct, and it took a lot to get accustomed to fitting them. Having considered what the key to fitting the ear hooks was, we discovered a form that was smaller than existing ear hooks, that didn’t utilise metal or resin wires and fit the ears of more people. We’ve achieved something that is slim and does not have a foreign feel to it, making for the kind of comfort that has you forgetting you’re wearing them. There’s also no problem with combining it with a figure 8 cable.

Cable noise – the unpleasant noise that occurs when the cable touches the user’s body when they are walking – is dramatically reduced.

 

Silicon carry case

With this silicon carry case, the cables can be rolled up and stored easily. The earphones themselves are gently secured using thin dome-shaped silicon covers.

 

Aging

Aging refers to the phenomenon whereby sound changes with sustained use over a set period of time. With the driver unit, the extremely thin film that is heated and shaped vibrates to create sound. The reason for this is not clear, but the stress from the adhesive and the stress applied when shaping the film settles down as it is used, and it is thought that perhaps micro-signals move more freely.

With this product, because of the small apertures, an extended length of time is necessary for changes according to aging become hard to identify. Generally, 150 ~ 200 hours of regular use increases delicacy and sound quality follows the intent of the original design.

* Since the reason for sound quality improving through aging has not been clearly established, nothing could be clearly stated about aging until now.

We have been checking this phenomenon, and have decided to express our opinions so as to collect as many questions regarding aging from customers as possible.
