The DA90 look plain and basic, however they contain some very powerful drivers in them, at least for bass! The loudness as a whole is higher than most earphones, and the frequency response is quite extended. However, this emphasized frequency range (especially the upper-lows/lower-mids range) causes the sound to be marginally bearable. Also, the special design is very comfortable at first, but after prolonged listening, some soreness or discomfort may occur. Use with caution.

Comfort & Fit
The earphones hold pretty well inside your ears by pushing against it. This, however, proved to be not entirely comfortable on long listening sessions, as the ears could feel a bit sore.
Lows / Bass
Excellent low frequency response. However, there's a high emphasis on the upper-lows, that cause the sound to be much more impactful and upfront than most earphones. This could lead to fatigue.
Mids / Vocals
Highly emphasized mids with an especially emphasized lower-mids cause the vocals to be loud and somewhat bloated and nasal. Also, louder-than-usual upper-mids cause percussion instruments to have some extra impact, which may cause discomfort and you might find yourself turning down the volume a bit. I should also mention that separation of different instruments isn't the best I've heard so far.
Highs / Treble
The highs are very pronounced and loud, but aren't that crisp. There's some slight darkness in their tone, which may have something to do with the emphasis on upper-lows, whose effect is felt throughout the whole sound spectrum.
