When I am using my headphones and listening to music on spotify I get an echo in the music. The background music is fine but the voice of the singer fluctuates. Mostly the voice decreases below the normal levels and it constantly echoes. I have tried fixing it through alsamixer and by installing spotify again but no solution.
How do I stop the echo?

I finally got it fixed after going through hundreds of lines of code and deleting and installing numerous software. the problem was solved when i slided the balance slider in sound settings to the right or left. it was initially in the middle which was causing the issue in the first place. after sliding the balance slider the issue was immediately fixed. no echo in sound and no bad sound quality. i suggest that people try this option.

This sounds more like a mechanical fault in the headphones or the jack.
There are three wires, left, common, and right.
If there is not a proper connection for the common wire, you'll still get sound, but it won't sound right.
What you'll hear is the difference between the left and right channels, with anything that is the same on both channels being cancelled out. You'll hear the various instruments fairly well, as they tend to be more in one channel than the other, but central sounds, such as a singer's voice, will be almost eliminated, sounding like what you call an echo.
What your solution of shifting the balance to one side did was to provide no signal on one channel, so there was no cancellation, and the one channel you were listening to sounded correct.
If what you hear is the same in both ears, with no stereo effect, this is almost certainly the cause.
A lot of times, toggling the bluetooth on/off works.
Command line: systemctl restart bluetooth.service
GUI: Settings->Bluetooth Click on the bar in the top right corner.
