Apple Music supports the transmission of lossless audio sources without extra charge (980 yen per month). The Amazon Music HD I signed is 1980 yen per month (1780 yen for gold members). On June 9th, the price finally dropped sharply to 980 yen per month (780 yen for gold members). Although it is about 1 month late from abroad, the result is very good if it is cheap! As a user is a kind of gratitude.

It is recommended to listen to a lossless sound source or a wired connection. The IPhone must be compatible with conversion adapters and high-resolution headphones / headphones, or headphones / headphones with Lightning connectors.
On the other hand, Android has a lot of terminals with headphone jacks, so in most cases you just need to have a high-resolution headset / headset. Products that support iPhone require MFi certification, so the price of each product is more expensive. It takes not only time but also money to get it together. If you want to enjoy lossless sound sources easily, Android is recommended instead of iPhone.
Apple Music and Amazon Music HD support frequencies per bit from 44.1 KHz/16 bits to 192 KHz/24 bits. To achieve the best sound quality, you need to set up an audible environment at 192 KHz/24 bits. The maximum frequency / bit corresponding to IPhone and Android devices is 48 kHz/24 bits. That is, the highest sound quality of Apple Music and Amazon Music HD is not supported by default. Therefore, we need DAC.
However, even the 48 kHz/24bit that can be heard without expanding the DAC is too high. If the price of DAC is high, in fact, most people don't need it. Therefore, this time to verify the extent to which the super-reasonable DAC that can be bought at about a thousand yen can be used.
Amazon Music HD allows you to view the sound quality of the song (the maximum sound quality of the source being played), the device performance (the maximum sound quality that can be played on the device reported on the operating system), the current connection status (the sound quality currently being played), and the codec. Redmi Note 10 Pro, Redmi Note 9s, Redmi 9T, moto G30, and Zenfone 7 display information for the following images: As mentioned above, if DAC is not used, the maximum frequency / bit is 48 KHz/24bit.
The device performance displayed (the maximum sound quality that can be played on the device reported on the operating system) is the same, but the sound is listened to differently depending on the device. Among Redmi Note 10 Pro, Redmi Note 9S, Redmi 9T, moto G30 and Zenfone 7, my personal favorite is Redmi Note 10 Pro. This phone even has the function of hearing test. I'm not alone.
The content displayed on the IPhone12mini is Kochira. Same as the Android device. However, don't forget that in order to deal with the headphone Jack, another changeover plug is needed.
Then there is USB DAC (Mudoki? Let's connect). This product uses a Hi-fi chip without the DAC mark. But the performance is similar, so it is used in this verification. The design of the logo is so subtle that it is rarely used. I thought the effect was subtle, but the result was surprising!
The maximum frequency increased from 48 KHz to 96 KHz. I didn't expect a definite performance improvement in less than one thousand yen. It really serves as evidence that DAC works. But the highest sound quality is 192 KHz/24bit, so it didn't reach that field.
The second is UGREEN's UGREEN USB DAC, which is cheap and looks good. There is a mark of DAC here. But the price is no different from the previous price. If you worry about which one to buy, it will be recommended to you. The clear reasons are also obvious from the connection results.
The highest value of Amazon Music HD with frequency of 192 KHz! If it is an Android terminal, the USB DAC connected to the thousand yen station can correspond to the highest sound quality of Apple Music and Amazon Music HD. It's a great price / performance ratio. When you actually install USB DAC, the sound increases to a recognizable level. It is understandable that there are an astonishing number of high comments.
And then it's finally iPhone's turn. I didn't have an iPhone DAC, so I went to buy a giant camera. Choose the cheapest (ELECOM), which is just a conversion adapter without DAC function! Just read the instructions carefully. But the conversion adapter is the most expensive of the three goods. MFi is terrible.
Because there is no way this time, verify the result of converting Lightning to a headphone Jack. The result is Coca-Cola. It's as expected, but it hasn't changed. I can just listen to music on cable. In terms of sound quality, the Redmi Note10 Pro that connects the headphone directly to the headphone Jack feels better, so it's not very suitable for listening to lossless sound sources.
Only the output validation of the iPhone conversion adapter is not good, so I bought UGREEN DAC on Amazon, which works best in Android DAC. Unexpectedly support MFi, barely about a thousand yen! If you're looking for it, you can have it. Comment is another thing, if you can, please read it!
Compared with more than 10, 000 products, the one that doesn't feel lost in sound quality is a headset called CCA C12. Because it is a cable type, you can also customize the cable according to your preferences. Because the design is very unique, I don't think it will be welcomed by thousands of people, but it is recommended to those who are looking for high-quality headphones at an appropriate price!
