At the minute I am having trouble with fit. I have large canals and have reverted back to the green large silicone tips. I am so used to just putting in my W4 within a second over the ear and now I am fiddling. Once I get myself a tip that is easy then I will be more relaxed. The last tip I found to fit really well with wear down IEMs was the large Phonak. I will have to purchase some unless some kind person has a pair and wants to donate.
With the above in mind, they are growing on me and with a perfect seal are sounding pretty decent. I am hearing things in the mids that I haven`t heard before. Great detail retrieval and imaging. I am not used to this so my brain has to learn somewhat.
Once I get over this tip business then my attentions will turn purely to the sound. I have even tried the left in the right ear but reverted back.
To sum up my early thoughts.... Engaging, very mid centric but I quite like that coming from slightly recessed W4 mids. There is a very slight harshness in the top mids but due to my tip mayhem and "just settling in" hopefully that will smooth out. Bassier than the W4 though. This is where I can hear the "Hybrid". Detail in the mids and highs and dynamic sounding bass.Yes I know that is how they are made but better bass than my BA W4 bass. Fast overall in all regions too. It is like vinyl (bass) meets CD (mids/highs).
All my listening has been the C&C BH amp with LF on which is how I listen to the W4`s.
Anyway, you will be pretty chuffed mate imo, not perfect but I will say again, engaging.
EDIT: Just ordered some red Comply T-400 tips which should be here tomorrow. Quick measurement with my MTPC, although the end of the MTPC is tapered it does go to a max size the same as the h-200. I ordered red also, just to match the cable lol (Which I will swap over tomorrow too from the black)
