hey thanks for that and the info about where I can try emOne more option at $299: https://www.massdrop.com/buy/inearz-zen-2-zen-4-iems - The InEarz Zen 2 with ADEL technology. If she listens to music at high volumes, that could damage her hearing over time - but the ADEL tech protects against that by releasing the damaging pressure. While it may drop isolation a dB or two, it is not enough to be noticeable, but creates a much nicer soundstage - think full sized HP. Was just on the tour and it sounds very nice. If you are in the US and want to hear them, you can try contacting @BulldogXTRM who is about to close up the tour. However, the Massdrop sale is only going on for another 5 days so you wouldn't get them in time and they are normally $370.
I've read about Adel and Apex and apparently (at the time I researched them) there was no hardcore data to prove it really does reduce hearing loss. I guess it needs more longterm use to see the results to compare to the typical rate of hearing loss. that's also why I thought an L shape signature would be good for her or at least a decent roll off on the treble. thank you!
for now I've lent her my e5000 but I'll eventually help her decide between the se215, some chifi iems I've been into recently, and now this Zen 2 ( soon before the drop ends)
thanks!
