Im guessing this one will make some waves. Been keeping an eye on it. I think fit is kinda of a problem tho

BA’s are strong with this one :+1:

Oh… I’m screwed.

@hawaiibadboy @Resolution Take one for the poor team?


This is a project I think a guy named Toranku took part in.
We had an amusing back and forth way back. He seems like a good guy. I hope he does well with his company which this is not. This is a set whose creation he took part in though.

I wish him luck. The tuning is aimed at Monarch and Variation fans and that is a lot of folks so I’m sure it is going to have a lot of fans.


Thanks for saving my waller, master. That won’t fit me confortably for sure.

Thank you! My firm (subtonic) did indeed help tune the Helios.
We’ve had a lot of fun doing this collaboration with Symphonium, and you will continue seeing our input in their future products. Stay tuned! :grinning_face_with_smiling_eyes:


I have just posted my review of these IEMs in the Acho Reviews thread:


The Helios is an astonishing first effort for Symphonium Audio and Subtonic and deserves to be considered a worthy contender in its price range.
