First CCA iem I all my others are TRN and I'm not disappointed. The only real complaint I have is not enough bass but I think I'm just used to the TRN tuning also eartips it came with are not to my liking, I would suggest the spinfits cp-100 for a good fit as the nozzle is small about 4mm. Casing is a bit thick of course with all the drivers inside, but nice comfy fit.
BASS is more then sufficient for EDM giving you a little "umph" when volume is turned up. Fast and not too forward and so bass heads ight want to try something else.No noticable bleed into the mids. Overall well-done nice bass with enough presence not to overpower.
MIDS ever so slightly recessed but full bodied and warm with voices coming through clear and never over powered violins and horns sound very good. Overall impressed with clarity in the mids.
HIGHS are slightly forward clear sharp with no piercing sibilance electric guitar solos are clean and detailed synths are amazing with these aswell.
SOUNSTAGE/IMAGING is good sounds have more then enough room to not sound jumbled sounds very even in length and width and gives nice 3D immersion. Great instrument seperation and layering you can clearly hear different instruments and where they are located.
Overall very impressed with these IEMs coming from TRN tuning which is a bit more fun V tunned but these have better technical ability and still deliver more the enough fun listening to music I would strongly recommend these to anyone. Also great for games
