some help to choose my next pair of earphones

[Ma77z]

Hi! I'd like to hear your opinion for a pair of <40€ earphones.
 
In the last 2 years I used Brainwavz M5 and Pro Alpha and was satisfied with them, but yearly one transductor stops working and I have to change them.
 
As usual I'm not sure about the next product I want to use. (I am tempted to go back to M5 or pro alpha but, to be honest, I can't remember how M5 sound compared to pro alpha)
 
I like earphones with some good bass (at least for this price) but I listen to kind of a lot of different music genres so I think I need something versatile like my two previous choices.
 
I always found good advices here, can you help me out?

thanks! Are brainwavz M2/M5/ProAlpha worth being considered or there is something better for their price? 1-2 years ago I had the impression that a lot of people here considered them sort of a must buy.
