A wide range of music has realized the impression of transparent sound, which is a sound that can be heard clearly even if it is localized at a distance.The development of the A series began with the establishment of a new evaluation method by analysing the relationship between sound quality and physical characteristics; the result was the A8000. The A4000 has further evolved that evaluation method. As a result of a new research targeting an evaluation method that matches the actual music listening situation, final were able to produce a product that can be said to be the definitive edition in this price range Review: 実はかなりすごいやつなのでは？ - 他メーカーの3万円以上ものや一万円以下なのに評価が高い中国メーカーのものなど、イヤホンをいくつか所有していますが、一番気に入っているのはこのA4000です。 なんというか、音が一番きれいに聞こえるんですよね。特に中音高音。 感覚的にノイズが少ないとか、解像度が高いとかでスッキリとして澄んでいるんですよ。そんな感じがします。 低音はやや物足りないという声もあり、私もそう思います。ただし音源によるところもあるかなと。 私は低音が強調されているものは好みではないため問題ありません。 Review: 大満足 - 音質としては大満足 オーオタではないのでこれ以上のレビューは難しいが、音質面でこれ以上を出すのは難しいと思う ## Features - Exceeding Sound Quality: Following the design principle of the flagship A8000, the new A4000 adds a new entry-level earphone to the A-series. With transparent sound and overwhelmingly natural response the A4000 provides localised and spatial sound that emerges with a deeply extended sound image. - Newly Developed High Precision Dynamic Driver: A4000 is equipped with a powerful high precision ‘f-Core DU’ 6mm dynamic driver unit newly designed from the ground up to create high-quality clear and powerful sound. - A Custom Made Feeling: final A4000 achieve an excellent, custom feeling fit based on a 3-point housing design that is considered by final to be the optimal solution for in-ear earphone fit without the feeling of unnecessary pressure. - 2-Pin Connector + Original OFC Cable: The 2Pin connector is a highly accurate in-house developed product that uses the 0.78 standard, which is said to be the most versatile. With a soft and supple covering material in consideration of touch noise, it bends flexibly even when using ear hooks, achieving a perfect fit. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08LMBJFGD | | Age Range Description | Adult | | Antenna Location | Music, Calling | | Audio Driver Size | 6 Millimetres | | Audio Driver Type | Dynamic Driver | | Box Contents | Cable | | Brand | Final | | Brand Name | Final | | Cable Features | Detachable | | Cable Length | 1.2 Metres | | Carrying Case Color | Dark Navy | | Carrying Case Material | Silicone | | Colour | Dark Navy | | Compatible Devices | Smartphones, Tablets, Desktops, Laptops, Car Audio Systems | | Control Method | Touch | | Control Type | Noise Control | | Controller Type | Corded | | Country of Origin | USA | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.4 out of 5 stars 699 Reviews | | Ear Placement | In Ear | | Earpiece Shape | Rounded tip | | Enclosure Material | ABS Thermoplastic | | Form Factor | In Ear | | Frequency Range | 20 Hz - 20 KHz | | Frequency Response | 20 KHz | | Headphone Form Factor | In Ear | | Headphone Jack | 3.5 mm Jack | | Headphones Ear Placement | In Ear | | Impedance | 18 Ohms | | Impedance Unit of Measure | 18 Ohms | | Is Autographed | No | | Item Weight Unit of Measure | 18 Grams | | Manufacturer | final Inc. | | Model Name | A4000 | | Model Number | FI-A4DPLDN | | Network Connectivity Technology | Wired | | Noise Control | Sound Isolation | | Number of Items | 1 | | Number of Power Levels | 1 | | Product Features | Detachable Cable | | Series Number | 4000 | | Specific Uses For Product | Music | | Style Name | In-ear | | Theme | Music | | Unit Count | 1.0 Count | | Water Resistance Level | Water Resistant | | Wireless Technology Type | Bluetooth | ## Product Details - **Brand:** Final - **Colour:** Dark Navy - **Ear Placement:** In Ear - **Form Factor:** In Ear - **Impedance:** 18 Ohms ## Images ![A4000 in-Ear Wired Noise Isolating High Precision Clear and Transparent Sound Earphones - Image 1](https://m.media-amazon.com/images/I/61ze6UISmKL.jpg) ![A4000 in-Ear Wired Noise Isolating High Precision Clear and Transparent Sound Earphones - Image 2](https://m.media-amazon.com/images/I/71SiKiV8iAL.jpg) ![A4000 in-Ear Wired Noise Isolating High Precision Clear and Transparent Sound Earphones - Image 3](https://m.media-amazon.com/images/I/71OUSwKVb2L.jpg) ![A4000 in-Ear Wired Noise Isolating High Precision Clear and Transparent Sound Earphones - Image 4](https://m.media-amazon.com/images/I/61X8WUHW6LL.jpg) ![A4000 in-Ear Wired Noise Isolating High Precision Clear and Transparent Sound Earphones - Image 5](https://m.media-amazon.com/images/I/71eu8szEtVL.jpg) ## Questions & Answers **Q: Where is this made?** A: Designed in Japan, made in China **Q: does this come with a in-line mic cable?** A: The cable this comes with does not have a mic. **Q: Can these be worn down or just over the ear?** A: yes **Q: I see that it has a 2-pin connector to the earbud but what type of plug is on the other end?
