TANSIO MIRAI Spark

Absolutely superb balancing, natural and detailed in a reference spacious dimensional presentation.

Highly refined in all parts of the sound tuning. Exquisitely immersive presentation that has you wanting to listen to just one more track. 3 tuning switches that slightly enhance the 3 parts of the sound profiles to your liking. Above average passive isolation and comfort in a thicker medium sized compact ergonomic universal design. Stunning vocal performance for both male and female.

Easy to drive but not a hiss magnet. Very versatile due to reference level balancing. Don't need an amp to go full on sparks sound. Tonally rich, airy with a clean separation and layering for your tunes that makes you realize just how flat and uninspired sounding your lesser earphones sound in comparison.

The Spark objectively and subjectively meets and exceeds my expectations. I feel like I can listen to this natural-sounding performance for hours, hear every bit of detail, and yet walk away without an ounce of fatigue. The Spark boasts impressive midrange imaging and a nice vocal presentation to go along with that punchy low-end and finely balanced treble. Driver counts do not really matter, but if designers know what they are doing with them, multi drivers can scale hugely and it seems Tansio Mirai has figured out how to implement them properly and exquisitely tune them in unison.
