Spectacular unboxing, I never thought a headphone costing this much would be this good, and not just in the unboxing, heh, great accessories with a nice case, good cable, only the Eartips kit from Tangzu already costs half the price of the headphone, haha. Fortunately, it comes with a cleaning cloth that, to be honest, is a work of art. In fact, everything about this headphone is a work of art. The case has a magnetic closure, the cable is nice and beautiful, everything matches well. The headphones have a good but simple construction, made of high-quality plastic, but there may be some small details that could be an issue during use. The material is simple plastic, so you need to be careful with drops and similar situations. And the main thing in an IEM is the sound. The sound quality is a spectacle, I'll exaggerate a bit, it's almost like a mini orchestra, deep sub-bass, strong bass when needed but without invading the midrange, natural and sweet mids without being too advanced or lacking in balance, and good, controlled treble with great brightness but still controlled, a great purchase and excellent IEM.
