I‘ve had the Clears for 2 years and IMO they pair well with the Chord DACs, I use them mainly with the Hugo2Go.
Their signature is balanced and detailed, really leaning neutral with a touch of warmth and a little bit of bite in the treble.
What strikes me about the Clears is how realistic and natural they sound to me.
That can take a moment to adjust to when I change from a more colored IEM or my DCA AEON Noire headphones to the Clears.
Especially coming from the DCA AEON the dynamic capabilities of the Clears stand out too.
One thing to keep in mind, being open back dynamic driver headphones the Clears have some limitations in sub bass boosting capabilities.
Listening at normal levels they are very good, but with sub bass heavy music at very high volume or with a digital bass boost you can reach their mechanical excursion limits.
What IEMs are you using and what is your tuning preference?
