I would suggest you try watching films or TV programs in English, maybe with English subtitles on, as well as listening to English music. I think that even if you don't understand everything they are saying, just listening to it a lot will help your brain get used to hearing the sounds. Hopefully over time you will start to understand more of what they are saying I am also having trouble understanding native Spanish speakers, and this is what I plan to do with Spanish music and films.

Hmm.. I would recommend you to watch videos from american/brittish youtubers! That's a good way for your ears to get used to how a native english speaker talks in reality since they use a more casual way of speaking, compared to how they talk in for example american dramas and movies ^^

I am crazy about listening English music when I studied in secondry school. My family all thought it would have bad effects on my study. However, they're proved wrong because I am good at English now. I tell you this is not to let you listen English songs but have a great interest in what you learn.

Find a English boyfriend~ haha
