I know there are lots of threads asking for recommendation like this one and as I don't want to steal much of your time I'll try to be as clear as possible about what I'm looking for.
My Brainwavz M3 broke after a year and a half of moderate use (its actually possible to listen to them but it's f**ing hard to get the cables in a valid position since they are really damaged in the inside) and I'm looking for a cheap replacement for them without losing much audio quaility. I liked the M3 mainly because they were very versatile, and I want to keep it like that but centering on my favourite music genres which are metal (from classic metal to sludge/stoner, progressive death, etc.), rock (Led Zeppelin, Pink Floyd, Foo Fighters...), and sometimes electronic (Aphex Twin, Chemical Brothers, Squarepusher...). I know it's a little difficult to combine electric guitars with punchy bass, so if I have to choose I prefer sharp guitars over overwhelming bass, but I'd like the earphones to be balanced if possible. Anyway, I rarely listen to very hard techno music.
Having a look at joker's multi-iem review i have narrowed the options to Xears XE200PRO and VSonic GR06, . The last ones are 10€ more expensive but they seem to have better build and sound quality and more accesories, but can only be purchased from China through eBay. Xears, on the other hand, seem more comfortable. Another option is VSonic GR02 Bass, but I don't know how it compares to the previous ones in terms of sound quality.
Just in case, some IEMs I discarded are Fischer Audio Eterna (seem too bassy) and Fischer Audio Silver Bullet (too fragile and poor build, considering that I have already broken a pair of IEMs).
Thanks in advance.
