The sound I feel with UM4 ear monitor as follows;
Bass- a profound, mysterious, broad and substantial bass make the natural sound in my ears;
Midrange-it is a clear,detailed and warm sound;
Treble- it is elevated, fast, precise and detailed sound make me feel with pleasure and vigor

I have a triple fi 10 and I have send it to this company in China to custom mod for me and they did a great job. I'm in love with my tf10 now and they are so comfort , much better than before. I use to hate the look and the comfort of the tf10 before and now i'm in heaven with them.
I will post some pic of my new tf10 later. Looks really cool i think. haha

Davidli, Could you please share your though of UM4 compare to other universal IEM from your experience ?

 

[Akabeth]

Congratulations! I hope you will enjoy them.

Impressions plzzzzzzz

 

[Davidli]

I actually enjoy them for perfect hand work and good sound!

I am happy with UM4 sound now,
It is a right decision that I sell TF10 and buy UM4;Soundstage is the same as ES3,but lower than UE11,Vocals is closer than UE11,But I prefer to ES3 vocals a little more;
Sound quality and quantity in low frequency range is more excellent,and deeper;Sound analysis is very strong,and for body noise detector…..
It is more sensitive for body noise than UE11
