Newbie here, and I apologize if this isn't the right place to post this, but I've got a new pair of HF3s (about 40 hours of burn-in on them at this point) and I've noticed some buzzing/light distortion when they encounter bass (and higher sounds) in certain songs. The volume on my iPad (all I have inbetween iPhones) is under 50% (and I'll hear it down around 10% too), it will happen on several songs regardless of the EQ (which is often off), and it's occuring on tracks that are 256kbps. These things have never been above mid-level volume. An example is Coldplay's "Lost!" track - in the fadeout where it's just the keyboard/, after each time it's played, I'll get a slight constant buzzing sound like the earphones are blown, or are just cheap. I alternate between the foam buds, the gliders, and the tri-flange tips, and I'm getting a good seal (deaf to the outside world with overall good sound). The same thing happens on other tracks which are a good bit "bassier" (e.g., "Daylight Dies" by Killswitch Engage). I know Etys aren't known for thumping bass, and I'm OK with that, but it's quite another thing to not even be able to properly play it. Given their stellar reputation, I'm assuming I'm doing something wrong, or I've got a bad set. Ideas?
