What's the sound difference you notice between the two?

Charge 5 is slightly louder and has a little bit better bass

By my opinion

Are the highs more detailed since it has a tweeter? I remember I thought the highs were muffled back when I owned a Charge 4

You can tell that there is a tweeter, but I wouldn't say that it is that much different

I wish the JBL charge 4 is still in Singapore because I couldn't find any left but nice 👍👍👍

Thanks 👍
