There are many kinds of wired headphones that we usually use, and then do you know what is Digital and Analog earphones are?
Analog earphones are our common 3.5mm interface earphones, including left and right channels.
The digital headset includes a USB sound card +DAC&ADC+amp+analog headset. When the digital headset is connected to a mobile phone (OTG) or computer, the mobile phone or computer recognizes the USB device and creates a corresponding sound card. The digital audio signal passes through After the USB is transmitted to the digital headset, the digital headset converts and amplifies the signal through the DAC, and the sound can be heard, which is also the principle of the USB sound card.
The type C earphone (middle picture) may be an analog earphone or a digital earphone, and it can be judged by whether there is a chip in the earphone.
Reasons to Buy Digital Headphones
Sound quality improvement
The 3.5mm earphones we use now require continuous conversion and transmission of audio signals from mobile phones, players to earphones; however, the signal will be attenuated and lost during the process. For digital earphones, the mobile phone and player are only responsible for transmitting digital signals to the earphones, while the DAC (digital-to-analog conversion) and amplification are performed in the earphones. The whole process has high efficiency and isolation, and there is almost no signal Loss; and the essential change of the improvement of transmission efficiency is the reduction of distortion and noise floor
Expansion of functions
In fact, the same as the Bluetooth device, the digital interface will bring higher authority to the headset device, Mic, wire control and other functions are naturally not a problem, and more functions will appear on the digital headset. Some earphones are equipped with a dedicated APP, and users can use the APP to realize functions such as noise reduction adjustment and sound mode switching to meet the user's personal listening preferences. If the app is not used, the user can also adjust the noise reduction and sound mode switching functions through the wire control.
HiFi enjoyment
Digital headphones have a sampling rate as high as 96KHz (or even higher), and can support audio formats with higher bit rates such as 24bit / 192kHz, DSD, etc., to meet users' pursuit of HIFI.
Accelerated power consumption
DAC decoders or amplifier chips need power to work, and mobile phones directly supply power to digital headphones will speed up power consumption.
