Hello friend! A friend of mine has bought these to have a sort of Aria sidegrade but in a neutral way. He says that he likes the neutrality and improved imaging too, so I guess it's a good news.

They are overall "lean" in the good sense of the word, meaning that their neutrality is reached with no issues and they are enjoyable. Sure not the most dynamic and fun earphone out there, but as you said there are other options for that in the market.

I tried them with bass boost and love the added punch, but I gotta say that I like them just as they are too (and I am a sub-bass and bass lover so...)
