I have noticed some say their Kemper sounds digitally distorted when playing DIRECTLY out of the headphone jack. I noticed it too. I just received my 3rd Kemper i.e. stage today and noticed it too. Here's what fixed it. I pulled out the headphone jack plug just a LITTLE and VIOLA!!!! STEREO BLISS. True stereo ping ponging with Delays etc. I mean just pull out the plug a LITTLE till you hear it clean up. I'll contact kemper on this as well. As an audio FOH mixer guy etc sometimes these things go bad and or the jack doesn't make the perfect contact. Give it a TRY!
Distortion directly when using headphone jack

Welcome, Michael.
I wonder if the tip of the TRS connector from your 'phones is more-triangular in shape and that a more-rounded one would've provided better contact, or vice-versa.

Are you using your telephone headphones, with a four conductor plug?

I presume many of the people experiencing distortion might be using low impedance phones which are being overloaded by the KPA headphone amp. The amps is designed to run 32 - 600 ohm loads so is pretty powerful.

just a curiosity.
Would headphones with impedance below 32ohm damage the amp or the headphones?
purely a curiosity I run AKG K240 with mine -
No.

... damage ... headphones?

Yes, if you connect very low impedance headphones and have headphones output set to maximum.

Sorry, lightbox is correct about the risk of damage to headphones if you run them too loud (risk of damage to hear g too at that level!). I only skimmed over the initial question and was referring to the fact that using low impedance headphones won’t damage the Kemper’s headphone amp. Solid state amps don’t need a load in the same way as a valve amp does.
