Initial impressions of TANGZU XUAN NV
As we are now acquainted with dual dynamic driver sets for the past few years, we are aware of some of its strengths and weaknesses. There are very few exceptional dual dynamic driver IEMS that I really impressed like the reminiscing analogue-ish tuning of the 7HZ Legato and CCA's well-tuned Duo that until now it remains one of my gold standard in terms of a well-balanced sound profile.
This is XUAN NV, TANGZU's latest entry-level product in collaboration with HBB. As I mentioned about the dual dynamic driver technology a while ago, this product also has this type of driver configuration. The dual drivers are encased in a 3D-printed acrylic resin shell with an acoustic tube for each driver.
On power scalability, this set is somehow easy to amplify but putting it with sources with a better power output will unleash its full potential to sound more dynamic.
As for tonal aspect, XUAN NV has a U-shaped sound signature with a balanced-warmish tonality that surprisingly doesn't align with usual HBB-collab sets on budget to entry-level segment. Bass response on this is quite incisive and precise , probably the cleanest bass response among the HBB-approved IEMs on the entry-level. Midrange is well-textured and has a good warmth for most male vocals and contraltos and mezzo-sopranos on female vocals to have an ample lushness, richness and smooth sound. Definitely, if you want a more crisp, energetic and glistening sound, this set will not give you those characteristics as its treble response is rather too smooth and even that treble heads will yearn more bright and shimmer.
On the technical side, this set performs quite average in my opinion on how it projects its sound/speaker stage, typical two-dimensional stereo imaging but it has a rather good separation and layering for a dual DD set. It is quite more resolving in terms of macro-dynamics and micro-detailing appears to be less sharper on extracting nuances and details.
