Great pair of entry level iems, especially for the price. I wish they came with a pair extra small sancai ear tips (the smalls are just a little too big for me) but that’s just a matter of how my ears are built. Been loving them so far!

TUNING PHILOSOPHY
In terms of sound performance, the Shangguan Wan'er SE has a more neutral sound style with less coloration, focusing on restoring the natural sound and the authenticity of instruments. Additionally, the overall resolution and clarity of the sound have been improved.
Compared to the previous version. The thickened diaphragm, lowered unit height, and enlarged hole in front of the diaphragm adjust the sound output, reducing bass to enhance treble clarity, making the overall listening experience more impactful.
ABSTRACT MINIMALISM
This time, we have redesigned the earphones to better match a professional appearance, with a stylish, minimalist, and understated style, highlighting the new professional tuning.
BLACK AND WHITE
Showcasing Elegance
Under the minimalist style, the black and white colors showcase an elegant demeanor: white like magnolia, black like onyx, calm and serene.
