If you want to play audio from your phone while the video is displayed on the display that your Chromecast is connected to, this post will show you if you can do it.
It is not possible to play Chromecast audio from your phone while you stream just the video to the Chromecast. However, you can get it to work with downloaded videos using the LocalCast app. You can also connect earphones to your TV or Chromecast (if you have a newer version) as a workaround.
Can I play Chromecast audio from my phone?
The way Chromecast works is your phone sends the audio and video as an integrated signal to your Chromecast and then that is used as an input into the display that the Chromecast is plugged into.
As a result of this, it is not usually possible to listen to just the audio on your phone while you are watching the video on the device that the Chromecast is plugged into.
However, there are a couple of workarounds which can allow you to achieve what you are looking for.
The first option is to use third party apps such as LocalCast which you can download on Android as well as iOS.
However, this will only allow you to do it with videos that you have downloaded. This will not work with videos that you are trying to stream from Youtube or Netflix.
The other option is to plug a bluetooth transmitter into your TV and then to connect some bluetooth earphones to the transmitter.
This will allow you to listen to the audio coming from the TV without having the sound come through the speakers.
If you have a TV that features Bluetooth, you can also connect some earphones to the TV. Additionally, if you have Chromecast with Google Tv, it features bluetooth so you could also connect the earphones to that.
Can I listen to Chromecast audio by plugging headphones into my phone?
You can listen to Chromecast audio by plugging headphones into your phone if you use the LocalCast app and you want to watch videos that you have downloaded.
If you want to stream videos from services such as Youtube or Netflix, it will not be possible to listen to the Chromecast audio by plugging the headphones into your phone.
However, what you can do is to plug a audio aux extension into the 3.5mm out on the TV and then to plug in the headphones into the other end of the extension.

Can I connect my earphones to Chromecast via Bluetooth?
Whether or not you can directly connect Bluetooth earphones to your Chromecast will depend on what version you have.
If you have Chromecast with Google TV built in, you will be able to connect your earphones directly with the Chromecast because it features bluetooth.
Otherwise, if you have a bluetooth smart TV, you can connect the earphones to the TV.
If the TV does not have bluetooth, you can also connect a bluetooth transmitter into the TV then connect the earphones to the Bluetooth transmitter.
