How to Combine Two Sound Sources into Headphones- Complete Guide

Although headphones are designed to be used with one sound source at a time, there may be times when you need or want to use two. For example, if you’re a musician, you may want to use headphones to listen to music while you practice. Or, if you’re watching a movie on your laptop, you may want to plug in headphones so you don’t disturb anyone else in the room.

There are a few different ways to combine two sound sources into headphones. One is to use an adapter that connects the two sources into a single input on the headphones. Another way is to physically connect the two sources together and then plug the combined output into the headphone jack.

Using Line Splitter Cables

Line splitters are a type of cable that is used to connect two devices together. They are commonly used to connect a computer to a printer or an external hard drive. Line splitters are also used to connect a microphone to an amplifier.

Line splitters come in different sizes and can be purchased at most electronics stores. They typically range from six inches to two feet in length. The most common type of line splitter is the three-pronged splitter, which has three connectors that fit into three corresponding ports on the devices being connected.

To use a line splitter, first, make sure that the devices you wish to connect are compatible with the line splitter you have purchased. Once you have confirmed this, simply plug the line splitter into the appropriate ports on each device. You may need to use an adapter if the ports do not match up perfectly.

Using USB Sound Adapters

If you’re not happy with the sound quality coming from your computer’s built-in speakers, or if you want to add audio capabilities to a computer that doesn’t have them, a USB sound adapter is a simple and inexpensive solution.

USB sound adapters come in a variety of shapes and sizes, but they all perform the same basic function: converting the digital audio signal from your computer into an analog signal that is playable through speakers or headphones after being amplified.

Most USB sound adapters also include a microphone input, so you can use them for voice chat applications like Skype or Discord. Some even have built-in microphones, so you don’t need to use an external one.

Using Audio Mixers

An audio mixer is a vital piece of equipment for any musician, band, or audio engineer. They are responsible for taking the various sound sources and mixing them together into a cohesive whole. Without a mixer, live performances would be nearly impossible to pull off.

There are many different types of audio mixers available on the market, from small, portable units to large-scale consoles. The type of mixer you need will depend on the size and complexity of your setup.

Using an audio mixer is relatively simple: each input (e.g., microphone, instrument, etc.) is assigned its own channel, and each channel has its own volume control. By adjusting the levels of each input, you can create a balanced mix that sounds good to your ears.

If you’re just getting started with mixing, it’s important to experiment and find what works best for you.

Potential Issues with Multiple Audio Sources

As technology advances, so too does the audio industry. With the advent of digital audio workstations (DAW), it is now possible to have multiple audio sources in a single project. While this can be a great way to add depth and texture to your music, it can also lead to some potential issues.

One issue that can occur is phase cancellation. This happens when two signals are not perfectly in sync with each other, causing them to cancel each other out. This can lead to a thin or muddy-sounding mix.

Another potential issue is comb filtering. This happens when two signals are combined and their frequencies interact with each other, resulting in an uneven frequency response. This can make certain frequencies sound much louder or quieter than others, and can ultimately make your mix sound less balanced.


Combining two sound sources into headphones is a great way to improve your listening experience. By using two different sources, you can create a more full and immersive sound that can help you appreciate your music more. Additionally, this setup can also help you save money by eliminating the need for two separate sets of headphones.


How do I combine two audio outputs?

To connect the two audio outputs we use an adapter such as a 3.5mm stereo adapter or a 6.3mm stereo adapter, through this, we can get clear sound.

Can headphones play from two sources at once?
