At nearly £100 they seem like quite an expensive IEM. How would you compare them to the likes of the IE7, EQ7 and SM3? I'm trying to get an idea of how these sound like, but from your "current iems" list there is little to compare them to! The Vsonic GR07 can be grabbed at just over £100, do you think these guys give them a run for their money? I realise the sound signature is very different, but in terms of technical ability and price/sound quality, how do these fare up? Certainly an interesting find. I'd personally probably be more interested in the neutral versions and not the extra bass one.
