第四世代カスタム13mm平面駆動型ドライバー搭載
Guaranteed Safe Checkout
「S08」の第四世代平面ドライバーの振動板はマグネトロンスパッタリングという高精度薄膜形成技術によって製造されました。
高純度銅を振動板に吸着させ、振動板の剛性を向上させることにより音の歪みを抑制した上、高安定性と高耐久性を実現しました。解像度が高く、煌びやかな高域表現を可能としました。
高精度薄膜形成技術以外、「S08」の第四世代平面ドライバーは伝統的な平面ドライバーの単層ボイスコイル回路と違い、二層ボイスコイル回路という新構造を採用しております。
二層ボイスコイル回路は直接に振動板を駆動して振動させ、共振を大幅に減少します。共振による歪みが極めて低くなり、過渡応答がさらに改善されます。
従来の平面ドライバーは質感のあり、深い低域を提供することがなかなか難しいです。低域表現を改善するため、LETSHUOERは第四世代平面ドライバーの開発を深く参加いたしました。
「S08」の第四世代平面ドライバーはボイスコイルの側に、PTR弾性フィルムを素材にするエッジを追加しました。エッジによって振動板の延性が増強され、低域の深さを大幅に向上し、弾力のある低音表現を可能としました。
同時に音場の広さと深さも増強され、豊かな音の体験を実現しました。
「S08」純正ケーブルは4芯*30本*0.05mmの単結晶銅銀メッキ線材を採用しており、高い伝送性能、繊細なディテールと豊かな空間感を実現しました。
さらに、3.5mmと4.4mm交換可能のプラグが付属され、 様々なデバイスと接続可能です。
As a professional opera singer and classical musician, I approach audio gear with a particularly refined ear, always seeking clarity, tonal accuracy, and faithful reproduction of acoustic music. I recently purchased the Letshuoer S08 planar IEMs and, overall, I find them to be a solid offering—especially at their price point.
Sonically, the S08 delivers a powerful and engaging listening experience. With the support of a capable DAC (in my case, the FiiO KA13), the IEMs are more than sufficiently loud and offer a smooth and rich tonality. However, from the perspective of someone who listens exclusively to opera, classical music, and jazz, I did find some aspects less suited to my particular needs. The overall tuning leans toward a darker, more bass-oriented sound, with less emphasis on treble clarity and airiness. In full-scale orchestral passages, the soundstage feels somewhat limited, and the distinction between instrumental sections can become blurred. For listeners who prioritize technical precision, openness, and a natural presentation of acoustic instruments, these may not be the ideal choice.
That said, these impressions are highly subjective and based entirely on my specific listening preferences. For general music enjoyment—especially genres that benefit from a fuller low-end—the S08 performs admirably.
The design and build quality of the Letshuoer S08 are impressive. The anodized finish gives the IEMs a premium and elegant feel. Despite being slightly weighty, their compact size allows for a very comfortable and secure fit in my ears. I can wear them for extended listening sessions without any fatigue—they sit so naturally that they’re easy to forget.
One point to note is that the nozzle insertion is on the shallower side. Personally, I prefer a deeper fit, though this may be due to my specific ear anatomy—smaller ears with relatively wide canals—so this may not apply to everyone.
The included cables are excellent in both appearance and function. They have a premium feel and, importantly, they don’t tangle, which enhances overall usability. Additionally, the M11 4.4mm upgrade cable comes with a refined faux leather case, which I find more fitting and protective for the IEMs compared to the standard round plastic twist-case.
Regarding the store: I initially had some concerns, as my messages regarding shipping status went unanswered, which left me unsure about the legitimacy of the site. However, those fears proved unfounded. The IEMs arrived even earlier than expected, well-packaged, and with a thoughtful gift—an M11 4.4mm upgrade cable. I also received a $10 discount through their mailing list promotion, and shipping to Austria was free. In the end, I paid just $79—a very competitive price I couldn’t find elsewhere at the time.
Overall, I would rate the store 4.5 stars, deducting half a star for the lack of communication, but praising the fast delivery and generous inclusion of a bonus cable. I can confidently recommend both the shop and the Letshuoer S08 for casual or general listening. However, if your focus is on high-fidelity playback of classical music, opera, or jazz, I would suggest exploring other options better tailored to those genres.
Classy, smooth (but not boring) sounding IEMs will well defined bass that come well equiped with a range of different ear tips, quality standard cable with both 3.5mm and 4.4mm fittings, and plastic storage case.Shipping was quick.
The S08 IEM is fantastisch in use and unfortunately need more bass
+ Rich sound + Wide soundstage + Excellent balance between coherent, well-tuned sound and strong technical component + Price Definitely one of the best purchases! They can really open up a new world of sounds for a beginner listener. I was pleasantly surprised how many new details I heard, even without an additional amplifier or converter (just by connecting to the iPhone). Very impressed! Now I'm already thinking about buying s15 or Cadenza4. I'll catch a good price 🙂 I want to sincerely thank LETSHUOER for their high level of technical development and desire to create new, high-tech products in their lines!
