I got my hands on the TSMR X, or Tansio Mirai X 10th Anniversary Limited Edition, as part of the AG Türkiye tour. For the first impressions and review data, I used the R4 with stock eartips and all switches set to their default positions. In this review, I’ll also explore how it plays with the high power.

Unboxing TSMR X
The TSMR X’s packaging gives off a premium vibe right from the start. Shiny green and white in color. And another visual fest after I slide the exterior box. When I opened the box, I found a beautifully designed pair of IEMs with a glossy finish on the resin shells and tuning switches at its back. Inside, there’s a well-organized setup with various eartips, a solid cable with 2-pin 0.78mm connectors, and a square shaped faux leather carrying case. Everything is neatly in place and thoughtfully put together, giving off a great first impression.

Sound Technical Details
The TSMR X uses a hybrid setup with 2 dynamic drivers, 4 balanced armature drivers, and 1 custom film retarding driver. All of this is housed in high-quality 3D-printed resin shells, offering a lightweight but sturdy design. The frequency response spans from 5Hz to 30kHz, promising a wide soundstage and precise imaging. With an impedance of 10Ω and a sensitivity of 103dB, it’s easy to drive with most portable players or phones.
The sound signature is both spacious and transparent, striking a fine balance between technical accuracy and musicality. It has a smooth but engaging tuning, with enough clarity to bring out details in complex tracks. The dynamic drivers handle the lower frequencies with authority, while the balanced armatures provide a clean and clear midrange and treble.
Bass
The bass on the TSMR X is smooth and well-rounded. It doesn’t slam with overwhelming force but instead delivers a controlled and tight punch that works well across different music genres. In rock tracks, the bass gives a solid foundation without overpowering the other frequencies. It’s well-balanced, making it a pleasure for both bass enthusiasts and those who prefer a more neutral response.
That said, in bass-heavy genres like drum ‘n bass, the lower frequencies don’t quite dive as deep as some might want. There’s a slight lack of impact, which could be due to the source or maybe the tuning itself. It doesn’t make things go wild, but it keeps everything nicely controlled, letting you enjoy a clean, distortion-free experience.
Midrange
The midrange is where the TSMR X really shines. Vocals come through with clarity and precision, sitting comfortably in the mix without being too forward or too recessed. When listening to bands like Cafe Anatolia, the separation of instruments is so clear that it feels like the musicians are right in front of you. The upper mids are particularly well done, adding a sense of air and space that suits acoustic and classical pieces.
However, there’s a bit of a V-shape in the tuning, so if the midrange isn’t mastered forward, the vocals can feel slightly recessed. This is more noticeable in electronic rock tracks where the midrange isn’t as prominent, but it still manages to maintain a musical presence that keeps you engaged.
Treble
The treble on the TSMR X is smooth and extends well. It has enough sparkle and detail to keep things lively without crossing into harshness or sibilance. This makes it comfortable for long listening sessions, allowing the highs to shine without tiring your ears. Cymbal crashes in rock tracks like those from My Chemical Romance have a natural decay and don’t come off as too sharp.
There are moments, especially in electronic rock, where the treble could use a bit more energy to add some extra excitement. However, it’s a minor issue, and for the most part, the treble is balanced well with the rest of the spectrum, resulting in a cohesive listening experience.
And with high power: source is iPhone 14 Pro Max, Deezer offline, and using the Questyle M15i via BAL connection.
The bass is especially emphasized, but the clarity has also significantly improved. The bass hits exactly as it’s supposed to, depending on how it’s recorded. As for the M15i, which I’ve always highlighted for its soundstage capabilities, it’s already impressive even on the R4, but with this setup, it’s just perfect. Hearing vocal harmonics alongside their physical presence is fantastic. However, due to the limitations of the source, the frequency range doesn’t go as low as it could, leaving both the dongle and IEM unable to fully capture that punch, especially in tracks like Swedish House Mafia. Still, the bass rhythms that follow are felt clearly.
Pros:
– Excellent instrument separation and soundstage
– Smooth and non-fatiguing treble
– Versatile bass that suits different genres
– High-quality build and comfortable fit
Cons:
– Vocals can be slightly recessed in some tracks
– Treble might need a bit more energy in certain genres
– Bass could use a bit more impact for bass-heavy music
TSMR X Review Conclusions
The TSMR X, with its 10th Anniversary Limited Edition status, brings a balanced and refined listening experience. It may not go very deep in the bass or have the most energetic treble, but its strengths lie in its transparency, clarity, and overall musicality. It’s a versatile IEM that handles a wide range of genres with finesse, making it an excellent choice for those looking for a premium yet engaging sound signature.
