This is the first time I have spent this much time with a planar iem. As far as my understanding of planars goes, they are a hit or miss in terms of timbre. However, with the S15, both timbre and tonality reach great levels. It is one of the good releases from the year 2023. Throughout my time with these iems I never had any complaints, and I enjoyed them as much as I enjoyed my other sets.
But the real question is: Is the price tag justified? I think that's a big question to answer. It's evident that Letshuoer has dedicated significant effort to deliver a comprehensive package with these in-ear monitors. The appealing aesthetics, solid build, generous accessories, and quality cable all underscore the team's commitment to providing a satisfying user experience. While all these elements are justifiable, comparing the S15's price point with other planars and some good non-planar iems reveals a potential disparity. Something like the Hidizs MP145 at 130 USD is a lot more justified when we talk about the price-to-performance ratio. In terms of sound quality, the S15 excels, but the pricing might be perceived as less justified when considering alternatives.
That being said, these iems are one of my favourites from the last year, and I am sure most of the people who have tried them would surely recommend them. They are a lot more than just impressive. Not only are they aesthetically pleasing, but their sound is also beautiful. Who knows, Letshuoer might introduce attractive discounts, making this great experience more accessible to a broader audience.
