Package, Design & Isolation;

Tansio Mirai TSMR-3Pro comes with simple white cartoon box. There is a big black case inside the cardboard box and the entire package is in this case. The package content is not bad at this price. There are lots of tips, a magnetized carrying case, cleaning tools, tuning switch pin. I would prefer hard case instead of that magnetic soft rubber case, but that’s fine.

The earphone design is very stylish. White faceplate and transparent body color are quite beautiful. You can make custom faceplate as well as many different color options. There are silver color brand name and logo on the faceplate but as I said, you can choose different customization options. TSMR-3Pro uses industry standard 2 pin (0.78mm) pin socket. You can use stock cable or you can upgrade it. The shape of the TSMR-3Pro is extremely ergonomic and it has a like ear-shaped design. I did not have any complaints for long periods of use. There are switches on the back of the earphones and they are pretty solid and not flimsy. Stock cable looks good and the cable itself is black 4 braided with 2 pin connectors. There are Left and Right marks on the connectors. Thanks god there is no memory wire and it is easy to use it. The isolation is also very successful and sound is not leaking outside. But like all other earphones, it depends on what kind of tips you are using.



Sound Type:

There are 3 switches and you can select from 7 different sound tunings with lows, mids and high switches. TSMR-3Pro has slightly warm bass, with smooth and slightly laid back mid and relatively prominent trebles. All switches have some affect on their frequencies but the difference between them is not drastic. Differences were mostly just a nuance and I listened mostly all the switches are down.

Probably treble is the best part of the TSMR-3Pro. The detail and the resolution level of the upper frequencies are impressive at this price. The sparkle and the extension are quite high. It is airy and spacious which makes the positioning of the instrument easy to hear. I have not come across any sibilance or harshness and never noticed any uncontrolled tones in the fast passages or multi stringed instrument parts on the music. Detail and resolution level are pretty impressive. TSMR is source sensitive and its sound character is drastically changing with the sources. In my listening with the AK120, the tops were slightly muddy and grainy, but when I listened with Opus # 1, I got a great clear clean performance. It is quite successful and natural when it is combined with the right source. It doesn’t make any mixing in the music and keeping its control. Overall, lively and airy presentation of the high frequencies is quite good, especially for its retail price.

The mid-frequencies are slightly leaned back and the overall presentation is lively and dynamic. The details are quite good and the presentation is musical. Even though the mids are slightly back into the overall frequency, the vocals are relatively forward. The vocals are smooth and realistic. I find it more successful especially in women vocals. The lower mids are a little lack in quantity, but with their success in other areas it doesn’t bothered me. Overall, the quality of mid is pretty successful but slightly missing in low-mid quantity makes the sound little bit thin.

The bass is not dominant and it has a nice authority in overall presentation, but this is not for bass-head level that’s for sure. Bass frequencies are sufficient in quantity and I can say that it is ideal for many types of genres. Some people may still want more in quantity for sure. Basses are not dry and it doesn’t feel artificial, timber is relatively natural. Lack of power and boomy type of beats offer advantages such as speed and recovery time. Sub-bass is not too deep and relatively rolled off, but this is not a problem for many types of music. Although it’s not good for EDM genres, it does well with other genres. In general, bass is quite successful with a quick and tight presentation and a relatively adequate detail and resolution.




TSMR-3Pro has a spacious soundstage and there is no problem either horizontally or in depth. It is airy and roomy enough to perform successfully on stage. With its clean background, the instruments are quite comfortably located on the stage, and are listenable without mixing and losing their resolution.




At 200$ – 300$ level competition is pretty tough in the market and there are many good earphones in this price range, and TSMR-3Pro is one of them. If you want it to get slightly warm, musical with highly detailed earphone, you might want to look at TSMR-3Pro. This is a great sounding earphone for its price. And also 7 different tuning option is great for whoever wants to play with various sound signature.
