Is the recitation of the Quran and listening to it acceptable from a person who watches pornography and masturbates almost constantly?

You must initiate sincere repentance, for sins can lead to a bad ending and make acts of worship burdensome, just as they tarnish the heart. Therefore, beware of them and do not underestimate them. As for your good deeds, Allah will not deprive you of their reward if they were performed in a way that pleases Him. However, beware that your sins might nullify the reward of those acts of obedience.
