The USB-C will transfer the signal in digital form. This suggests that a device connecting to your USB C cable should be able to convert the digital signal to an analog signal before your headphone can begin playing the audio. Remember speakers are only compatible with an analog signal, therefore they have to be converted back. But if you have a good digital-analog converter then your output will be better and compatible with your headphones. Make sure not to use a cheap digital to analog converter so as not to have a horrible output.

3.5mm Headphone Jack:

The 3.5mm-audio jack transfer audio signal in analog form hence your device requires no further conversion. The analog signals are capable of vibrating the diaphragm at your speakers or headphones which will finally result in audio-output. Your digital audio on your device is changed to analog form by the in-built sound-card on the device.

However, if one has a high-end amplifier that has crossover circuits that can increase this signal more times to give you a loud 5.1 movie-experience, then one may notice that the audio gets distorted at bigger volumes. The reason for this is the output of 3.5mm jack attempts to increase the analog signal a little bit to operate well on speakers. To minimize the problem you need a high-end sound-card or reduce the system volume by 30 percent.

Audio Quality:

USB-C audio quality wholly relies on its specific build quality while the audio quality produced by a 3.5mm depends on its in-build quality & the sound source. You may also discover that other headphones aren?t loud enough when you connect to your device. This reason behind this is that additional power is needed to initiate the speaker (audio drivers).


Most USB-C based speaker/earphones will need an external power-source & some might even utilize power from USB-port itself though more 3.5mm-based headphones will operate with no external power required.

USB Type-C has power transfer specifications which are incorporated with USB-C connector specifications. USB Type-C is very powerful in a way that it can give out much extra pure & premium sound quality. However, USB-C has 24-pins and 12-pin are active at a given time, therefore, when you are using USB-C Audio-Accessory, there?s a Vconn line that can give more power. On the other hand, 3.5mm-jack has minimal power output abilities due to a three-wire connection.

Process Involved:

In 3.5mm headphone the process involved for you to hear the music includes getting the music form file storage then move it to DSP decoder or encoder, then the song is amplified and converted from digital signal to analog signal for transferring it to your speakers via the 3.5mm cable.

In USB-C, the process involved includes getting the music from file storage, take it to DCP encoder or decoder and take it to the USB-C port of your device where it is tapped by USB-C cable and transferred in terms of digital data to a digital-analog converter and then amplified. After all that it is transferred to your speaker (driver) for you to enjoy.


3.5mm headphones are much cheaper and readily available even in your local shop which USB type-C is expensive and one can have a hard time finding one when in need of replacing it.

Extra Features:

  • USB Type-C can be improved to send extra data not just audio whereas in 3.5mm jack it has no room for that. It is just made to transfer audio-only.
  • Smartphones made with USB type-C port are thinner and comfortable than smartphones with 3.5mm audio jack which are bigger.
  • When with USB-C, you will be unable to charge your phone and at the same time use listen to music because you will have to use the same port while on smartphones with 3.5mm headphones jack, you can listen to your audio and at the same time charge your device because it has distinct port for different purpose.
  • USB-C is likely to data transmission errors due to clock jitter while in 3.5mm this is not experienced.
  • USB-C is not compatible with most devices in the market today while 3.5mm earphone jack is compatible with almost all devices that are present in the market.


If you need any of these headphones, make sure that you choose the product that has the most positive reviews and manufactured by a good brand or company for you to have a better experience. When you are buying 3.5mm based headphones, check on the drivers and don?t choose the ones that are too big because they require extra power input for them to operate effectively. Small phones might not have sufficient power to operate with 2 big Left & Right drivers on big headphones which eventually leads to inaudible sound output.

On technology, the best way to go about this is just via a wireless connection. Bluetooth connection is an advanced technology that is compatible with most phones including phones that are not smart. As long as it is Bluetooth enabled, it will be compatible with your Bluetooth headphones. A major advantage of Bluetooth headphones is that it has its power source therefore you don?t have to worry about whether the power of your phone will be sufficient.
