Hello dear Giacomo Paganelli The small Cassette players currently on the market do not have the automatic stop function in the fast forward and rewind functions, which requires us to stop manually We are also satisfied with the level 4-pole jack you mentioned, but you are buying the basic style, this function can be matched with you only if you choose it Thank you very much for purchasing our products, and thank you for giving us positive feedback. We will pay attention to these issues and continue to optimize them in the future. Thank you
