Hi guys, I just got my bezza. But found out the sound quality is not so good. Cant really hear what is the singer singing sometimes.. I suspect it's because the speaker at the door and lower position?

My friend suggest me that adding some small tweeter will drastically improve the sound because the high frequency cant travel far, thus it's good to be close to the ear. But I saw some post above, there are mid-range, full-range, tweeter. I wonder which to get?

Any recommended shop? or lyn user?
Btw, my budget is low. I just want some cheap solution to at least improve the sound quality abit so that at least I can hear the lyrics. probably like 100-200. Thanks
