Stable sound field open iron triangle ATH-AD2000X earmuff headphones

Extra large earmuffs, thick ear pads and a closed outer casing are common design elements of the Audio-Technica iron triangle earphones, but have you noticed that the company's Air Dynamic series is somewhat different in the existing design? Based on the changes, the most obvious difference is that the earmuffs are changed from closed to open design, which looks lighter and more "airy", giving high-end headphones players different voices from the previous iron triangle.

The protagonist of this audition is the flagship model of the Air Dynamic series - ATH-AD2000X earmuffs earphone (hereinafter referred to as AD2000X), the reference price is 32,000 yuan, the price is second only to the highest level of the iron triangle ATH-W5000 earmuff headphones. In design, the AD2000X maintains an oversized earmuff, which has the advantage of completely covering the ear without squeezing it into the ear shell. In addition, the original factory emphasizes that the ear pad is made of suede cloth coated with low-rebound foam material to reduce skin contact. The pressure on the face, wearing a 3D wing head pad with a hollow design above it, is one of the signature designs of the Iron Triangle. It is also to reduce the wearing pressure. The actual wearing of the AD2000X is very comfortable. The earphone is clamped on the head. The strength on both sides is moderate, and it is not easy to fall off. The stability is very good.

Although the volume does not look small, the weight of the AD2000X is only 265 grams (excluding the line). It won't feel heavy when worn for a long time. The reason for keeping it lightweight is that the main frame and the rotating shaft are made of lightweight magnesium alloy. Made of open earmuffs using a honeycomb-shaped perforated aluminum alloy casing, looking inward from the honeycomb-like casing, there is a circle of regularly arranged white squares, the original explanation, this is a new development baffle with a fin-shaped air path, both It is a design that combines strength and weight. If you add the hollow 3D wing head pad and thin metal bracket design mentioned above, it can reduce the overall visual weight.

Generally, the earphone earphones have a single size of 40mm, but the AD2000X uses a moving ring of up to 53mm. It is equipped with a Permendur iron-cobalt magnetic engine. The voice coil is made of 7N-class OFC, which is 99.99999% pure. The oxygen copper material is used to make the voice coil winding, so that the AD2000X has ultra-wide frequency response data of 5Hz~45kHz, and the maximum power of the original factory is up to 2000mW. At least you don't have to worry about the headset being mistreated at all! Another item It is worth noting that the earmuff has a three-fixed Diffuser near the center. This is a new design of the iron triangle. The purpose is to spread the air inside the earphone to make the sound field wider and wider.

The AD2000X has an impedance of 40 ohms and an efficiency of 103dB/mW. It is directly driven by the body source and has sufficient volume. Listening to general pop music or vocal singing can be handled with ease, but the low frequency is flat. For example, Jacky Cheung in 1994. The "Hungry Wolf Legend" released, the sixth track "very summer" is the song that Zhang Xueyou and Wang Fei sang together. First, use the iPhone 5 to directly drive the AD2000X to listen to this song. The volume control of the mobile phone is adjusted to about 60% and there is enough sound. Pressing, the low-frequency rhythm of the beginning of the track sounds more relaxed and less sullen. The songs of Jacky Cheung and Faye Wong are very clear but slightly thin. So I switched to the Bobby ear of the electric Flint to listen to the same song. The track just started. The low-frequency rhythm immediately became clean and Q-bomb, and the strength of snorkeling was much better than using a mobile phone. The important thing is that the vocals become thicker and without losing detail.

For example, Nils Lofgren's "Acoustic Live" album, the fifth track "Keith Don't Go" starts listening from the mobile phone. Nils Lofgren's guitar low frequency sounds more relaxed, after the ear expansion, the low frequency The beam is solid and thick, and the shape of the guitar sounds more clear. When the bass is played to the bass, the rhythm of the strings is naturally extended. You can hear the vibration details of the strings. The treble performance is more delicate and clear than before. Keep the steel strings to play the sounds and not too irritating to feel the enthusiasm of Nils Lofgren.

Listen to the performance of the stringed instrument and replace it with the play of Paganini's "Diabolus in Musica". The violin and the triangle are matched with each other. The high-frequency sound line is clear and shiny, so it won't be too rushing, so it doesn't sound harsh. It can keep a lot of details, the thickness of the sound is just right, it sounds natural and dynamic. When the orchestra begins to play, the whole momentum begins to emerge, the scene is calm and level, and there is no confusion. The sound of the violin solo has a rounded texture without excessive swelling. The refreshing style, the whole sound field is naturally open and relaxed. When listening, the volume of Bobby's ear expansion has been adjusted to 0dB (minimum volume -60dB). I don't feel noisy or harsh at all, but can concentrate on immersing in Aka. More skillful string sounds.

Overall, the performance of the AD2000X is quite balanced and not exaggerated. The details and levels are rich and natural, and there is an open sound field performance. It is not easy to feel the listening pressure for a long time. In addition, the AD2000X is not difficult to drive, usually used. Convenient, you can get enough volume with direct drive from the source.
