Here I have the Tanchjim Mino: Asano Tanch from Tanchjim—a model as adorable as its name suggests. Thanks to HiFiGo and Tanchjim for the opportunity. Let’s see how its BE-coated diaphragm translates into sound performance. Since the previous TWS model, the Tanchjim MINO, also featured a BE coating, these two will inevitably be compared.
Sound Details__
Without using any dedicated software, even on an iPhone, it delivers sound that far exceeds what I would expect at this price point. As I play Riverside – Friend or Foe Live, I feel like I’m right there in the middle of an excited crowd. The band performs with all its bass, drums, synths, and guitars in full force. Vocals are decently clear, and the sound fills my entire hearing space as if my surroundings are immersed in music. During the guitar solo, the notes soar skyward, and thankfully, the upper treble holds its ground. The bass-driven rhythm at the end of the track was a unique and unforgettable experience.
Then came Shaka Ponk – 6x Love. It’s like the track demanded my attention. This time, I switched to Foobar2000 as the source. By the time the famous Samuel Jackson-inspired monologue rolled in, I was already in an eargasmic state. The musicality and technical clarity were so tangible—it’s hard to believe this is coming from a TWS.
Later, I queued up Avantasia – The Tower, a song I first heard back in my college days on a cassette from a hardcore Manowar fan. Back then, it left me awestruck, and this time, the Asano Tanch left me just as amazed. The majestic bass-heavy opening and rapid power metal rhythms took me away, as I sat in my darkened room with the lights dimmed for a late-night Squid Game binge. What truly stunned me was how clearly it rendered the riffs—something I never thought possible on a wireless device.
From there, I jumped back to the ’80s with Toto – Africa. The Tanchjim Mino: Asano Tanch showed a command over playback that rivaled wired headphones. Everything was smooth, with punchy bass rhythms and solid control. The mid and upper treble exceeded the typical limitations of TWS devices, delivering playback that genuinely felt Hi-Fi. However, when I tested Alboran Trio—a more challenging piece for headphones—I had a “wow” moment. It managed to deliver tones in such a way that both its technicality and musicality stood out as exceptional for its price.
Comparison with Tanchjim MINO
Looking at it from the start, the BE diaphragm in both models ensures that the musicality isn’t radically different. Like the Kiwi Ears Cadenza, both models lean towards a dark, calm, and musical presentation. However, the Asano Tanch manages dynamic range better, handling even the most complex passages with more finesse.
One area where it shines is its handling of string instruments—they’re reproduced without becoming boomy, maintaining a Hi-Fi level of precision. This improvement is noticeable even without actively focusing. Similarly, wind instruments sound authentic and true to their source.
Pros
• Outstanding musicality
• Lively and dynamic playback
• Hi-Fi-grade sound quality
• Retains control even in multi-instrumental, organic passages
• Dark-leaning tonal balance without sacrificing clarity
Cons
• It’s difficult to find an objective downside.
• The accompanying app is only available in Chinese.
• The soundstage isn’t particularly wide, tall, or deep.
Final Thoughts on the Tanchjim Mino: Asano Tanch Review
For years, TWS earbuds were more about convenience and call quality than music. But as technology advanced, finding a TWS in 2025 that is balanced, clear, detailed, musical, and dynamic is extraordinary. The Tanchjim Mino: Asano Tanch proves that wireless earphones can now truly cater to audiophiles, blending convenience with a rich, engaging sound signature.
Could this be the future of TWS devices? With models like this, I’d say yes.
