+1. Btw, I get quite a nice SQ by inserting the ed9's fairly deeply and getting a good seal (which I could only do once I tried some other non-stock tips). Without doing that, they don't sound good. I wonder if that's the problem people are having?
Good points. $155US on amazon is pretty good. The main niggle that holds me back is how the resume works (re-starts track). I doubt that will ever be resolved via FW upgrade. And using rockbox (once developed) has it's downsides for me as well. Hmm. I'm also very interested in the M1s, but the price is higher and it only has a single card slot. Hmm.
I'm usually fairly treble sensitive. But I didn't notice any issues with the ED9 for quite a few days (using the brass nozzles). But then listened to my Nighthawks again for an extended period and switched back to the ED9's. Mistake - the highs sounded a bit much (damn you Nighthawks!). I still like the ED9's though, so we'll see how I feel down the road.
