Hi guys,

I got a filter blocked on my Chu2 as well as on my Kefine Delci (original). Whilst ordering replacement filters on Ali, Kefine sent me some for the KLEAN instead of the Delci.

Surprisingly those fit the Chu2. It makes the tip significantly wider though. I'm therefore using coffee eartips.

I cannot tell about changes tonally as I just don't use the Chu2 for music. I use it for calls and those eartips don't seal much my ears but are very comfortable (I know that's very personal).

Cheers!
