Love the sound of this item except for it has a lot of basses and the volume is quite small compared to other true wireless such as WF-100XM4. But the worst part is the app is literally garbage that cannot even able to use. Tried to connect to the soundID app with 5 different devices from DAP, Android phone, Ipad... but none of it managed to connect to the app and just keep showing me a stupid unable to connect screen. After trying like 4 hrs and just ended up just deleting this stupid app. Love the product. But you guy's partners must enhance the performance of the app
