Update on my E8 journey from the prior pages (last post here ICYC:
https://www.head-fi.org/threads/goi...are-we-there-yet.861024/page-83#post-14533225)
The new pair of E8s has burned in and the volume is almost as loud as the Soundcore Liberty Lites that I used as a volume measuring stick. They will not make my ears bleed, but they're too loud for most purposes. The old pair couldn't be heard clearly over airplane noises, So, tremendous improvement.
However, it's also much, much warmer and "friendly" sounding - not at all clinical like the defective pair I had previously. Lots of mid-bass, recessed high-mids, the top of the highs cut off. Seems like this formula is now the go-to for most wireless headphones. Detail and separation is pretty impressive.
The app seems to make a whole lot less difference with the new pair, too. "Warm" just fuzzes everything up. "Energetic" and "Bright" don't do a whole lot, but what they do sounds a bit artificial. The widened soundstage seems to remove the details too much. Everything sounds best with it centered and the circle at its smallest.
Unfortunately, what I think I want is a pair with the sound signature of the first pair but the volume of the second pair. My dream would be wireless ER-4Ps. Sigh.
