Mine are still burning in and they are a little bass heavy at the moment. I have fitted Spiral Dots which have added a bit of sparkle in the treble and I plan to use a TRI Through cable next although I was surprised by the quality of the stock cable. Work in progress...
I'm using wide + shallow bore CP360 (TWS) that tightens the bass. It is still a significant part of the overall picture but its cleaner. Any silver you can throw it will help too!
