"Overall, I was very impressed and can't believe these have been out since 2018 with very little western presence or hype. In a world where Odin is ~3k USD, and Trailli 6, I'd say these are appropriately priced. I judge pricing mostly on technical attributes (detail retrieval, imaging, dynamics, etc.)" solistice15 Head-Fi

Aroma Audio ACE

Flexible sound signature for all musical preferences

ACE can switch between 4 sound signature modes by moving 2 switches

J --Jack, Bass mode

This is the mode with the widest range of bass Frequencies among the four sound quality modes. As opposed to a general bass boost, it is tuned for the optimal balance taking into account the fog in the mid and low range. Excellent for expressing beats.

Q --Queen, Treble mode

Of the four sound signature modes, this mode optimizes the expression of high frequencies. In particular, it focuses on the output of the ultra-high range, the main point of sound field representation, and is excellent for locating each instrument and expanding the sound field. Suitable for relaxing and listening to great classical music.

ACE, Balance mode

In Balance mode, musical expression is natural and vocal expressiveness is excellent. The localization and presence of the instruments is clear, and the sound field is precise. This is the default mode for ACE.

K-KING Vocal Mode

In this mode, vocals stand out the most among the four sound quality modes. The delicate and smooth sound quality expresses vocals and background noise very well. The sound field is narrower than the other modes, making it suitable for solo singing and small pieces of music.
