Sengdong Hack 1.0 + Redeem Codes

This is not as useful as it could be. When looking at the volume screen, making a change in volume to the headset directly does not automatically sync with the volume screen.There is no explanation of what differentiates the four pre-programmed presets. it would be extremely helpful if after choosing one of the presets, when you look at the equalizer page it would show you exactly what each frequencies are being affected. Sadly this does not show you that. Certain parts of the app show Chinese characters instead of English. The overall design of the app needs work.
