2-way frequency division

To achieve high quality performance with minimal distortion, Witch uses a two-way physical frequency split arrangement for both driver units. The dynamic driver unit delivers quick, punchy, deep bass and rich mids, while the balanced armature driver delivers high-resolution detail in vocals, mids, and highs.

The one I borrowed from the manufacturer this time is not the official package, so I give it a rating of 7.5.

 

The full version comes in a package with a cute picture of a witch.

Sound quality general comment
  • Original Sound Fidelity: B+
  • Recommendation: C
  • Personal preference: C

 

The Open Audio Witch is supposed to be the maiden product of Open Audio, but it can be said to sound like a cheapo, as is often the case with bubble manufacturers. The sound is reminiscent of the early days of Chinese earphones just 10 years ago, and in terms of sound quality, it is not a model that one would pay 10,000 yen for. The specs are lacking, and the tuning is at a level that audiophiles with even the slightest ear for detail would criticize harshly, and it really isn't good.

 

There are better competitors in the same price range, such as the Tin HiFi T3 Plus and the ThieAudio Legacy 2, making the Witch's presence even more hazy.

Fortunately, I have already reviewed the Alkaid from the same brand and know that Open Audio's sound has rapidly refined since Witch.

As such, we do not recommend Witch if you have heard of Open Audio's excellent reputation and are considering it as an entry-level device.

General comment

The Open Audio Witch is an earphone with a heavy donkey sound. The build quality is not bad, and the distortion ratio and other measurements indicate that they are probably made of materials that are worth the price. However, the tuning is simply not good, and we do not recommend them.
