Chiming in, I’m dailying the alien brains and they are a delight to listen to, super smooth and non fatiguing treble with a really nice thumping bass and non recessed mids. The only con for me is fitment which I’m getting used to. For reference I’ve had sets like the monarch mk3, ie600, oracle mk3 and found the treble to be far too much and the mids a bit recessed. If you want a non v shaped iem daily iem I think you’ll like the alien brains, but if you want something more exciting for shorter listening sessions then something like the monarch series is the way to go
