Redmi K50 has a headphone jack. The Redmi K50 does not use a 3.5mm round headphone jack, but uses a Type-C interface shared with the charging interface, located at the bottom of the fuselage. The Redmi K50 uses a Type-C headphone jack, which can bring better sound quality and make the body simpler; in the future waterproof design, it can be more closed and have better waterproof and dustproof effects.

Redmi K50 has a headphone jack. It does not use a 3.5mm round headphone jack, but uses a Type-C interface shared with the charging interface, located at the bottom of the fuselage.
Advantages and disadvantages of Type-C headphones
Advantages
Can bring Better sound quality. In addition, the mobile phone can cancel the traditional 3.5mm headphone jack, making the body more concise. Especially in future waterproof designs, it can be more closed and have better waterproof and dustproof effects.
Disadvantages
There is no traditional headphone jack, and it is a bit troublesome to use an adapter to be compatible with ordinary headphones. Additionally, if the phone is charging, you cannot use the headphones to listen to music unless you use Bluetooth headphones.
Generally speaking, smartphones cancel the traditional 3.5mm headphone jack, which has both disadvantages and advantages. From the perspective of development trends, it will be a trend for future smartphones to cancel the traditional 3.5mm headphone jack.
Redmi K50 is equipped with a Samsung 6.67-inch OLED screen, covered with Corning Victus glass, 3200×1440 pixel resolution (2K), supports HDR10/10 display, and has 120Hz The screen refresh rate and 480Hz touch sampling rate, picture detail, color accuracy, and sliding smoothness are all great. The fingerprint solution is still a side physical/fingerprint two-in-one button.
In terms of core hardware configuration, the Redmi K50 uses the Dimensity 8100 chip. The one we have is the 12GB 512GB top version; the front camera is 20 million pixels, and the rear main camera is 48 million pixels. Sony IMX582 sensor supports OIS optical image stabilization, an 8-megapixel ultra-wide-angle lens with a field of view of 119°, and a 2-megapixel macro lens.
Another big highlight of this phone is that it has excellent battery life. A large 5500mAh battery is inserted into the body of the Redmi K50, which is matched with 67W flash charging. It is a relatively balanced battery life solution that takes into account the use time without compromising too much on the charging speed.
Extended knowledge: The difference in sound quality between Type-c headphones and 3.5mm interface headphones after they are converted to Type-c
There are two main aspects that determine the sound quality:
The first is the distortion and noise in the digital-to-analog signal conversion process;
The second is the sound quality of the headphones themselves.
Therefore, we cannot generally say which of the two methods has better sound quality, because we don’t know the quality of the DAC chip or the sound quality of the headphones.
Generally speaking, I prefer to use headphones with a 3.5mm interface and connect to the mobile phone through a type-C conversion cable for three reasons:
(1) A wide range of choices
Most of the mainstream wired headphones on the market have 3.5mm interfaces. With a wide range of choices, it is easy to choose headphones with better sound quality;
(2) Professional DAC chip
Part Type The DAC chip of -C headphones is poor, or even without a DAC chip. This kind of headphones can only use the DAC chip that comes with the mobile phone.
In order to save space in current Type-C mobile phones, the size of the DAC chip is generally smaller and the performance is poor.
It is better to choose an adapter with a professional DAC chip, which has less distortion and less noise.
(3) Wide range of use
At present, in addition to mobile phones, speakers, mp3 and other audio equipment still mostly use 3.5mm interfaces. Choosing 3.5mm headphones has a wider range of uses.
To put it simply, the most essential difference between the Type-c interface and the 3.5mm audio interface lies in the different decoding methods.
The traditional 3.5mm headphone jack can actually only transmit audio signals. To put it bluntly, it is the function of wire connection. Therefore, the phone performs the decoding work and transmits the analog signal to the headphones through the 3.5mm audio interface. Headphones are only responsible for converting audio signals into sound. The Type-c interface has relatively powerful data communication functions, so the decoding chip is also transferred from the mobile phone to the headset.
