TSMR 4 Pro Review – Love and some more

There are a few Chinese brands that have left a mark in the market lately with their tuning and fantastic value propositions. Tansio Mirai or better known as TSMR has been one of them. TSMR has been very precise and careful with their earphones. The solid build quality has been consistent since their inception. They started with the TSMR 3 back in 2017 and now they have some of the best IEMs which are equipped with tuning switches to provide some variations of the base sound signature.

The TSMR 4 pro is one of the most promising earphone for under $500, priced at $319, it house 4 BA drivers in a 3 way crossover and comes in a lot face plate and shell color options. The market is flooded with options in this price. The TSMR 4 pro faces tough competition from earphones like Moondrop Blessings 2, Penon Orb, Secret Garden 3, Avara Av3 and the DUNU DK-2001.

Get the TSMR 4 pro from here:


TSMR hasn’t changed the packaging scheme, it is exactly same as the TSMR2 and 3. Similar set of accessories too.

The retail package is not exactly elegant, it is more functional though. One basically doesn’t fight with the box while taking the earphones out. You get a large zipper pouch stuffed inside a card board box. The carry case is as big as old gen external hard drive case. It is big enough to carry the earphone and a portable DAP.

Inside the box are the earphone and a pocket friendly carry pouch. Placed inside the pouch are 6 pairs of tips, a cleaning too and a tool to flick the tuning switches.

One will find a hand book explaining the switches finishes the list of accessories.


Build quality of the TSMR 4 is very good. It doesn’t have the semi custom type body but sits inside the ear comfortably. The shell is made out of resin and feels very solid to the hand. The back plate is fused with a few layers of resin on it and the shells walls are thicker than most of the earphone.

There is a reason why the body feels stronger, you cannot put the switches on a weak shell and expect it to hold up. The switches are nicely fused and there is no need to worry about the setup coming off. Feedback of these switches is good but it is on the stiffer side. The 2pin port is flush on the body and removing the cable is fairly easy and smooth.

The nozzle is wide. Any T4/500 size tip will fit, I am using stock wide bore tips.

The resin..


The cable is okay. If the Inear SD5 and Fibae 3 cables are bad, there is no need to complain here. The biggest thing I don’t like about the cables is its cable guides. It is tight and can be uncomfortable over a longer period. Yes, this much of clamping is helpful when you like to go jogging with the earphone, but I don’t find it good to use headphones or earphones while on the road where one has to be aware of the surroundings.

Moving on to the braided 4 core cable, it is supple and doesn’t have much memory problem. It is not bouncy and doesn’t have much microphonics either. The 3.5mm jack is metal clad and has good amount of protection to it, same goes for the y splitter. There is a cable slider too. The minimalistic design of the slider and Y splitter is always welcome.


I find the TSMR 4 pro to be more comfortable inside the ear compared to the Fibae 3 or Shozy pola, the reason being the combination of nozzle depth and size of the shell. The shell fits better inside the ear and the longer nozzle gives very good stability.

Ergonomically it is average, it doesn’t have any type of wing to have better grip inside the ear. What really helps is the light weight. It is far less heavy compared to the Shozy Pola and is easy on the ear too. Thanks to the aggressive cable guides one need not to worry about the earphone falling out of the ear.

TSMR 4 has very good isolation from outer noise.

My humble audiophile journey started in 2010, when I was in college, where I fell in love with the elements, nuances, and variations of this mesmerizing world. The ability of tiny earphones to recreate amazing sounds made my bad days tolerable and good days better! Now I am a full-time audiophile with a preference for musical tracks, especially vocals and engaging ones. I must admit I am addicted, but not to drugs or alcohol, but to earphones. Come join me as I share my experiences, bad or good, and let’s have some fun!
