TRN ZS1 IEM earbuds

This is the last IEM model i received bu this time from the ebay in around 25 days via speed pack the newse4rice between eBay and China for a bit 'faster reception'. There is a problem with this service that the packs ater being delivered in Greece are then left in the carrier service for unknown time and finally delivered in more than 20 days after. This happened with some midMay orders As for example a ties mini pack has been sent form the seller on 10May , arrived on my country on May 26th and still on 14-6 the parcel has not been received . This is the biggest problem of someone who monitors the orders via various tracking services

Now back to the subject . TRN is a company as the KZ in the same city Shenzhen making IEM earphones with good specifications . But just look at the box design Its very similar to the KZ models The only difference are the size by only 1-2 mm wider . Buds are put in exactly the same way as the KZ The only materiel that separates from th KZ crowd are the mini information , in different folded document and of course the angry Chinglish but using good and easy to read fonts The wording seems as like it was translated by Google !


The cable is quite thin and sodt and can be  tangled very easy 'As sluts' as ew call this phenomenon in Greek Many times i spent too much time to untangle it in order to use it in my ears . I kept the, plugged into the earbuds and i do the same in all other models

The buds are very close to the ZSN in size and appearance but the design is quite different 

Performance

The audio level is not so strong as with the KZ models and is much closer to the Sound magic model And very different to the KZ models and is heard as generally poor  INoder to get the best audio i had to add the wide eartips that add a huge bass in the sound

This is a comparative comparative audio response as based in aural listening There are a little bassy adds but the trebles are qiute higher which remind the standard audio quality of BLON03 as noticed by others IN a way this can be called as subtle trebles especially in the higher part of the band 

Comparing to the ZSN its sounds with deep bass missing and treblier in the higher part 

in this article i have listened to these very beautiful story songs from MSia and Insia

  1. Segalania pasti by Aida Agil a rock song 
  2. Euphoria by Rere Reina a disco song in English
  3. Semaking Sayang by Wulan Alora a dangdut pop song


They were also tested and compared with the tones test  audio yelding the following curves

The part on the left is from KZSN the other is the TRN with just 3 db of difference in amplitude 

And  this is the difference between the two earbuds in terms of frequency response


-------------------


A nice notice

Just looking at the plugs the have nearly the same length and distance between the poles 

As for example  the plug of the EDX can fit perfectly into the socket of the BLON03 but the cable plug of the BLON 03 cannot be plugged into the EDX as tits cable is protected by a cover 

this is the proof of the above 

I have also tested the plug of the TRN to perfectly suit into the socket  of the KZ ZSN . in this way i have tested  he sound of both and well he
