Sound quality description

In this review, I use the standard eartips size L and drive it with the FiiO M15.

 

Open Audio Alkaid has a V-shaped sound balance with emphasis on high and low frequencies.

 

Please see here for detailed reviews on sound quality.

 

Sound quality general comment
  • Original Sound Fidelity: A-
  • Recommendation: S-
  • Personal preference: S+

 

The Open Audio Alkaid generally meets the price point standard and has the ability to be a high-end earphone.

 

It has a delicate, shimmering high frequency range, a soundstage with depth and analytical sound with high resolution.

 

However, for the hardcore audiophile, who generally tends to focus on the purity of the sound image in the midrange, its slight lack of midrange may push the Alkaid somewhat lower from being a candidate for best companion. The overall range reproduction is also slightly lacking for a high-end product.

General comment

The Open Audio Alkaid is a high-end earphone with a delicate, analytical sound with high transparency across the entire frequency range. Although it suffers from a relative lack of midrange clarity, the perfection definitely meets the price point, and it delivers vivid, sparkling music with a deep soundstage.
