I tried to delete the two songs and could not. I could not turn on the English version and there were no instructions on how to do it. I tried using it for maybe an hour or more with no luck . It only had 3 buttons, volume and screen. The touch screen did not work for me very well. It had instructions to reset, it did not seem to work for me. I am sure it is a very good unit , and someone with a little more tec knowledge would really enjoy it. I elected to return it ! ## Features - 300mAh lithium polymer battery with low-power design offers about 50 hours of wired earbud playback and 7.5 hours of FM radio recording. Fully charges in 2 hours, perfect for travel and sports. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0GC4HWKF5 | | Batteries | 1 Lithium Polymer batteries required.
