In life, many of our smart phones are often used to play music, so a good sound quality phone is actually very important. But when we change the phone, many people only pay attention to the processor, pixel, fast charge, and for the sound quality of the mobile phone, the requirement is that it can only play music.

At present, many smartphones on the market are supplemented with related sound technology. How can we judge the sound quality of a phone without knowing the professional knowledge?

Mobile phone price and positioning

If the price of your phone is within 100 USD, the sound quality of the smartphone can be no more demanding. Because it will be controlled by cost, and smartphone manufacturer will not spend a lot of time on sound quality.

Whether the headphone jack has been canceled

The mobile phone that keeps the earphone hole has a certain space because the earphone is plugged into the inside of the mobile phone, making it difficult for the phone to optimize the DAC and the PA. After the phone cancels the earphone hole, the position of the original earphone hole moves to the outside, so the space is freed to improve the sound quality of the cell phone. This may be one of the reasons why Huawei, Xiaomi, and nuts have successively canceled the earphone hole.

Of course, there are some phones that have not canceled the earphone jack have good sound quality, mainly due to their optimization and the support of exclusive sound technology.

Some people may feel that the sound quality of the phone that cancels the earphone hole is also normal. For example, the iPhone, the audio output is a digital signal, if the sound quality is poor, a large part of the original conversion line is not used. Another example is an Android phone. The audio output has two kinds of digital output and analog signal output. If the sound quality is poor, you can try the conversion line with DAC.

Does the phone add sound technology?

At present, there are not many phones that focus on music, but many mobile phones now feature Hi-Fi high-fidelity sound quality. In general, when we choose a mobile phone, the phone with the ESS decoder of DAC generally has the best sound quality. It can eliminate the noise floor and achieve pure sound.
