1. The button SWEEP generates a sweep of variable frequency from 10 Hz to 20 KHz and constant volume, however most headphones will not reproduce all the frequencies of the ends and will show variations of volume throughout the range.
2. The VOICE button shows an acoustic recording to check a natural sound in your earphones or speakers.
3. Earphones Test+ is an application designed to test your earphones or speakers by evaluating different quality parameters and verifying compatibility with your android device.
4. MUSIC plays a digital recording to check the fidelity and clarity of the sound in your earphones or speakers.
5. STEREO test to check the perception of the stereo and sound location. BUTTON test.
6. Press the 1000Hz reference button and the variable frequency button alternately to compare both volume levels.
7. Find the minimum level you can perceive and see if each jump is heard as double the volume of the previous sound.
8. DYNAMIC plays a fixed frequency with variable amplitude to see if the headphones enhance or attenuate the weaker sounds.
9. This is another way to check the linearity to find if there are tones that sound louder than others.
10. At the right and left ends you will find more frequency values to help find the response limits.
11. With the CHECK LR button Identify the left and right channels to verify that they are properly wired and placed.
1. What I was really looking for is an app that would let me check the audio quality of my headphones : the app would play a music track, then degrades some aspects of it (encoding bitrates, low frequencies, high frequencies) and asks me if I notice a difference.Great app.
2. My thanks to the developer! 👍 Keep up the good work!!!Great tools!! Will be more great if it can identified what kind earphone does user use, is it TRS, TRRS, CTIA/OMTP, USB, BT.
3. Adding microphone test would be great too1st thanks for this app and i'm using lot of time when repair my headphone or earphone.
4. Also it would be great if there was a left - right test with different tones to test balance on both device and ears.Great this app cleared a lot of things for me.
5. I would really recommend it to anyone and no ads, thats great.Keep up the good work.This is probably the most effective and accurately described app that i have ever downloaded free or othersise.
6. The audio output is nice and loud, which helps me to locate my TWS earbuds if I manage to drop one or both of them.A free,lightweight,ad free app, fantastic ! Just for that, I can't give less than five stars despite some shortcomings.
7. Thanks a lot.This is an awesome tool for checking quality of headphones, and also can check if stereo speakers are wired properly.
8. I suggest having different voices for the voice test, adding a female voice would be nice.
9. With the relevant test I can quickly estimate headphone quality, and identify issues and with the physical connection.
10. Thank you to the developers!Love it! Great interface! I like the customizable buttons.
11. I advice lowering the volume if you are testing using headphones, might get a jump on the high frequencies.
