In case you're streaming Bluetooth from a cell phone and notice the sound quality take a plunge, attempt this: Close any applications you have running that tap your gadget's Wi-Fi, cell, or GPS associations particularly those that stream information, in the same way as Spotify or Youtube. These can meddle with the Bluetooth indicator. In case you're utilizing a music application, set it to download tunes ahead of time instead of streaming them continuously. Otherwise you have installed Volume+ on your device, you can navigate to Settings > Sound > Music Effects and activate Volume+. Then, you can launch the app itself to customize speaker/in-call/headset settings. You can choose pre-included EQ settings and personalize your own.
