Tansio Mirai TSMR-4 Pro

Rich & Detailed.

PROS: Sound and build quality, detailed sound (good amount of micro-details), good attention to design details and QC, customization options.

CONS: None really at this price point.

Disclaimer.

I would like to thank Tansio Mirai for sending me the TSMR-4 Pro to test and review. I am not affiliated with the company or any of its sellers and write this review with an unbiased opinion regardless of how the review turns out.

Genre preferences.

I majorly listen to rock, acoustic, pop and metal and occasionally listen to EDM songs which are doing the rounds on the radio and charts.

About Tansio Mirai.

Tansio Mirai is a boutique brand manufacturing in-ear monitors out of Beijing, China. TSMR is a few years old and is run by a young entrepreneur who was initially an artist and sculptor before turning to manufacturing earphones. Since he studied art and sculpting in college, you can see the finesse in his craftsmanship, designs and custom hand painted shells. He runs a tight ship and anything coming out of his laboratory guarantees high quality craftsmanship.

Included in the box.

I was sent just the IEMs. I do not know how the packaging looks or the accessories that will be in the box. So, for that matter, I’ve left out the ‘In the Box’ section of this review empty on purpose.

Build Quality, Fit and Comfort.

The universal shells of the whole TSMR line up are the same. The shells are made from resin and are stunning to look at. There are innumerable customization options where sky is the limit. The shells are extremely well made and you can clearly see that the attention to detail is top notch.

Fit, like previous TSMRs I’ve tested is very comfortable and snugness primarily depends on the choice of ear tips. The shells aren’t like the semi-custom shape that you see a lot of companies using but they still provide similar isolation from outside noise. I’ve used them while travelling by public transport and never knew what was happening around me while listening to songs. Also, the nozzles aren’t intrusive and remain comfortable over long sessions.

Pictured case and cable not included in the package. This Tanchjim upgrade cable was used for testing.

  1. Hi!
    Did you listen TSMR-4 Pro with Opus #1s?
    I’m looking for multi drivers IEM with neutral sound.
    I prefer refined sub-bass, clean, not receased mids and natural treble with good extentions without any peaks…
    Thanks!

    1. Hey! Sorry, I don’t have the Opus #1s. TSMR-4 Pro is very much like what you’re looking for. If your budget is around its price point, give it a shot.
