I think my comparison wasn't very good. It isn't a matter about sound signature, but it´s about characteristic of most BA earphones. The ATH-CK10 and Westone 4 have this a slightly plasticky character in the mids, but the GR07 and EX1000, like all dynamic IEM that I heard, don´t have that.
My friend has the JH Roxanne. He told me that Roxanne is unique BA earphone that doesn´t have this a slightly plasticky character in the mids.
I didn't mean the sound signature either - I meant the character of the mids specifically. If you're looking for something that sounds more like a dynamic driver or SM3, the JH13 isn't it.
