Having a quick listen with my iPhone & Fiio E11.
Not as harsh as I thought. A hint of sibilance but not prominent. Highs certainly sparkly though.
Thankfully the mids are quite present, I would say on a neutral scale (compared to AD900)
Without the E11, these are ice cold, giving that metallic sound signature. The E11 is adding a hint of warmth for sure.
And yes there is BASS! Nicely textured with body and smooth extension. Its Ultrasone punchy (not AD900 punchy).
It will never have authoritative slam like the Pro 900, but I'm appreciating the quantity so far.
Just documenting a few things from a fresh 1 hour perspective. More to come.
