Ratings and reviews

Couldn't possibly be any easier to use. Wear your headphones, launch the app, and touch anywhere on the screen. A voice will say "left, right" one time in the corresponding ear, while the other side remains silent. It also lights up a drawing of each side of a set of headphones while each tone plays. Touch the auto repeat button at the top of the screen to play each tone and light up each earbud in what is most likely an infinite loop. Easy to use and accurate.

Does exactly what it says on the tin and gets the job done. ✅ This application tests internal and external left and right speakers. This is especially perfect for those external devices that have no markings to determine which is left or right, and the fact that it is "cost free, has zero clutter, is of a small size, and also free of ads" is the icing on the cake. 🍰 This is simply a 5 🌟 application for what is was designed to do. Big thanks to the developer for a no nonsense application. 👌🏼

Simple, lightweight and efficient. Works great for my dollar store headphones. Note: I too was hearing "left" from each channel separately while playing music. Stopped the music and heard both left and right. I think this only happens when media is playing on certain devices or with certain apps (FM radio). App works flawlessly.
