Usually narrow bore silicone tips do tame down the treble peaks, including final E tips and something like the Sony hybrid ones. They don’t compromise as much as foam tips and fit great with the tia trio.Trying my new Tia Trio and it’s intense. Don’t know if i can take the highs … love the bass it slaps like no other.. but I think the highs are a little to much for me changing cables trying different sources to see if can control a bit more the treble but it’s aggressive … still my preference is the U4S the treble is on the limit for me , more smooth and I can listen for longer time.
I little disappointed , really wanted to like the trio , I like it but I think I can’t take the treble.
I use the stock spinfit tips and they are a great middle ground compared to the other ones 64 audio provides. Super comfortable too!
