Here is a link to my review:

Here is my summary from that:
Overall
What we have here is for £115 a great IEM and a real contender in the price range. It offers a great neutral dynamic signature with mid-bass no BA IEM will be able to replicate but that being said BA IEMs do things that the GR07 can not. If you want neutral with good mid-bass slam then for £115 this would be the obvious choice in my opinion but if that is not your priority then do not right out the Rock-IT R-50 and the Brainwavs B2 from the scram and I am sure there others that would join the scram.
I have enjoyed my time with these dearly and would like to think my review of these is a bit more controlled compared to some peoples rambles of love about them being a review so I hope you enjoyed this and thanks again to Nuckin Futz for loaning me these!
