Brief Introduction to Open Audio Witch
I’ve heard Open Audio (later will be reffered as OA) since 2018, but they use illegal drugs as product names (which is not good IMO) such as Khat (2BA), Ecstasy (3BA), Marijuana (4BA), Ketamine (6BA) and Alkaid (8BA).
At beginning of 2021 they released OA Witch which use 10MM Titanium Diaphragm Dynamic Driver combined with Single BA (Bellsing 29689).
OA Witch has stunning box presentation with lot of small details (definitely a good one).
OA Witch equipped with lot of accessories such as 6 pairs eartips, Magnetic PU-Leather case, cloth wipes and lastly 4-core SPC cable.
Build quality is excellent, very light and really good fitting.

Sound Quality Evaluation
This Review using Quloos QA390, YinLuMei A1S and F.Audio FA2 as source.

High Frequency
Slender and clear treble with good amount of quantity, though upper treble control kinda lacking which result upper treble feels a bit fluttering.

Mid Frequency
Forward vocal, thin cold sounding, good control there is no sibilance nor harsh sound, good vocal texture

Low Frequency
Deep, powerfull, good texture elastic bass. Overall good control with few exception the bass could be lack of control if the song demand large dynamics. But it’s should be one of the best bass performer for the price range

Separation, Soundstage & Resolution
Soundstage width is good, while the depth need some work (acceptable on the price range, almost all IEM sub $200 quite lacking in depth). Instrument separation is good enough. For resolution just at the right level for the price range.

Personal Comment
Hybrid single DD and single BA, kinda hate that combination because there’s always some problem. OA witch also has that incoherency though not as bad others (like QOA vesper or Pink Lady). Put aside incoherency problem, OA witch actually quite balanced and quite good product, don’t forget it has really good box presentation and build quality

It just need to understand what OA aims with this product, definitely not an allrounder IEMs.
Should I buy OA Witch?
Depends on what you’re looking for. If your playlist full of Pop / Vocals / ACG, then OA Witch is a good to buy, but if you looking for allrounder IEMs, you can choose something else

Recommendation Level: ★★★☆☆
In the end only 3 stars recommendation, good sound is not enough for today competition. There is so many good product at low price which can offer higher value. Audio brand need more effort to acquire marketshare.

That’s all my review of Open Audio Witch, hope it helps, Cheers~
