Unfortunately, I can't compare as I have not had a BA4. They are a huge jump up from my HY3 however, which were previously my favourite IEM.I would certainly expect them to be a step upgrade from the BA4, but how big that step will be, I am not qualified to judge. You should talk to Phil and he will advise, I'm sure. Proper impressions of the 6P I will post in due course, I want to spend a week with them first and try all manner of recordings with them.
