You could optimize your Android audio experience through the settings. Not all Android UIs have this feature, however, so it won't work for everyone. If your device has it, the procedure is easy, though. And once you've done it for the first time you will be able to quickly enhance your audio settings in the future.For TouchWiz, you need to plug in whichever audio device you want to use (if you're using one). Then, hop into your Settings and tap Sound. From there hit Audio settings. You should have a series of options to enhance your audio experience. MIUI from Xiaomi, has an enhancer for headphones. Just toggle it on and pick the type you're using. You should have the choice between in-ear and normal headphones. Xperia UI allows you use the ClearAudio setting and has an equalizer. You can get to it through the settings. With Sense UI you can toggle BoomSound but there's really no reason to turn it off, as the audio is terrible without it on. You can't optimize your audio settings from Oxygen, Optimus or Stock Android.
The default audio controls on most phones, with the exception of Sony phones and the OnePlus 2, are not exactly comprehensive. Some include a basic EQ but it often only works within the default music app and provides no control over audio not played through the music player.It's important to note that no app works miracles when the hardware is not working properly but with a couple of simple adjustments your sound quality can be improved significantly. So hit the Play Store and get yourself a decent EQ. We can recommend both Music Volume EQ and Bass Booster.
If your phone has a protective case or cover, it will affect the quality of the sound you get from the speakers. All those vibrations coming from inside your phone will be muffled by the additional layer of plastic or rubber that the manufacturer won't have taken into account when designing its speaker system.Not all case makers understand the subtleties of your device. Some cases block essential parts of the phone like the audio jack, microphone or speaker. Before you buy a case be sure that you check to see that it won't block anything.
If you are rooted, there are plenty of app options out there that can bypass the max volume of the Android system with a few simple tweaks. If you don't want to root your phone or simply aren't convinced by the distortions that most volume-booster apps in the Play Store end up producing, then there are still a few things you can do.Get to know a little about sound waves. If you position your phone in a corner and fire the speaker output towards it, you'll get a louder, 'bassier' reverberation than if it was just shooting out into the room. The same logic applies to any object: put your phone in a box, against a bowl or in a glass (empty, of course) and you might be amazed to hear how much louder your speaker suddenly is.
