Here are some of the TB review comments I extracted from Don Scorpio Dolphin and Drama headphone. However, there ain't much comment on DRAMA.
Suitable for live vocal or sparse instrument music. Not appropriate for heavy, orchestra, rock and similar type of music.
It is the sound that I like. Highs are not dull with controlled bass. There is sound seperation.
Though not as stunning as DRAMA. High and mid are more thorough (revealing).
Those who prefer more bass should go for DRAMA, while those who love vocal should go for DOPLHIN. It tends to give an air of clarity. New headphone may sound thin and hopefully, it should resolve upon burn-in.
DOLPHIN looks better than DRAMA and it has the same type of good built quality. Pearl white does not look as good as shown in the photo. Thus, recommended to go for luminous ocean blue color.
The sound quality is good, but it has a different sound characteristics which tends to clarity. DOLPHIN low cannot be compared with DRAMA but has better high and mid. At least it sound more balanced. 480 is definitely value for money.
Meanwhile, I just have to save up for DRAMA. I still cannot forget DRAMA's comfort ever since, though it does not look as good as DOPLHIN.
Lows are well controlled, high and mids performances are very outstanding.
Hopefully, it will give us an idea of their sound difference.
