Good news everyone! After many weeks of waiting and arguing, the shop agreed to give me another pair of Havi's or give me back my money. But they said if I get another pair of Havi or any else chinese brand the warranty will not be applied to the cable. So I took my money and now deciding what to buy. The problem is I live in place where all shops are not easy to deal with when you have an issue while on the warranty.
I have listened to some other popular IEMs such as Brainwavz R1(V-shaped too much), Brainwavz M3(too flat mid-highs), MEElectronics M-Duo(V-shaped too much), MEElectronics A151P G2(less bass and sub-bass, less soundstage), HiFiman RE-400(less sub-bass, less airy) and T-Peos Opera(more detailed in acoustics genres, but too sibilant in rock/metal).
And I must say - Havi B3 Pro 1 is the best of them all for me when it comes for sound and fit. T-Peos Opera is better in some genres of music, but Havi is just good in much more quantity of genres if you have a good source. But the cable is terrible. The first day I saw it I thought "I should use it very careful" and I was right about that.
So maybe you can give me an advice what IEMs to choose to replace the HAVIs? If I don't find any I will buy Havi again and make some cable-mod or something like that to prevent it from braking.
