Stereo Test - Left and Right

Earbuds, earphones, or speakers' left and right channels should be tested.

An app called Stereo Test - Left and Right allows you to determine which earbud or speaker is on the left or right.

Some speakers, earphones, or earbuds don't tell you which ear is on the left or right. This can be a problem because we need to put speakers or earbuds in the right position when watching movies or playing games.
