I still recommend you to use headphones.
Low end. First push
The bass performance of Kossspp is very strong, and sound stage is full.
Followed by mx660.
This is the middle and low-end earphone with the best comprehensive performance I have ever used.
You can read it in the encyclopedia. The prices are all between 300 and 500.
In addition, don't use the speaker. One is disturbing the people, and the other is not effective.
