Technology: very difficult, very difficult to produce.
Its earplug shell is made of zirconium alloy, which is at least twice as hard as titanium alloy. Its characteristics are high temperature resistance and corrosion resistance. Because of this characteristic, nuclear reactor fuel rods use it as a material. Not only that, but its assembly is also very difficult. Otherwise, it will not be released from 18 to 19 before it is officially released on February 20th, 2009. At that time, Sony tried many methods but failed to increase production. First of all, it is very difficult to process the pattern of its shell. Secondly, the earplug structure is adopted. Two turns and one iron, two turns coaxial? In addition, the assembly of Shen Yan cavity is difficult, and the quality and process requirements of its parts are extremely high, so there can be no gaps. It is said that an old master can only make three a day. Many earplug designers are also lamenting: "Only Japan can achieve this level of detail. ? Moreover, throughout Sony's history, there are not only models that have been discontinued due to difficulties in mass production, but also the king of palladium moving coils MDR-R 10 and QUALIA017-MD. Maybe Sony will stop producing IER-Z 1R one day or replace it with a shell material that is easier to process, and the price may be higher then.
Technology: As always, the technology independently developed by Sony has been adopted.
It is a customized high-definition hybrid drive unit system developed by Sony itself, which is limited to its own use, and realizes ultra-wide dynamic range and HTC sound field. Moreover, this technology will not be sold externally and is exclusively owned by Sony.
Sound: both high frequency and low frequency are excellent.
If IER-M9 is cold and cold. Then IER-Z 1R is more water and agile.
The high frequency is very sharp, smooth, transparent and full, and it is endless without sawtooth and burr. The high frequency curve is very stable and smooth, giving people a very confident feeling. It is also the confidence and strength of the price of Z 12999 12999, not counting IQ tax.
Low frequency: very clear and powerful. 澎湃 The clear and tangible low frequency is amazing, and it will not have any discomfort and influence on the middle and high frequencies. (It is not recommended to match the warm front end of Jinbao line and BRIC, and triple comfortable earmuffs, because it will make its low frequency unsatisfactory. )
