So I am preparing to send my second set of HF3's in for replacement after less than three months use, first pair went pack after 1 month. I travel and work nights frequently, so I wanted a clear IEM to block airplane and hotel noise, which these do exquisitely with comply tips. I typically listen to classical (more piano and violin then full orchestral) which these excelled at as well. I use my iPhone with them exclusively and never over 50% volume, in fact 10-15% is normally effective with the comply P-series tips. On occasion I will sleep with them in, but on the lowest volume possible just to drown out daytime chatter while working nights.
If the etymotic reputation is to be believed, what can I be doing to blow the drivers? I've tried replacing tips, filters, and even holding the monitors up close to my ear with no tip or filter and the distortion is the same. Its very clearly a blown scratching sound and is very pronounced on voice calls and seems to get worse as the volume is increased with music, though not consistently at the same points in the track . I have tried both calls and tracks with my other earphones - iPhone speaker, skull candy buds, skull candy aviators, sony MDR 1, and none repeat the scratching. I was sooo happy to finally get a decent sounding set of buds, but bummed that they don't seem to last. Surely they are designed to be more robust than this..?
Thanks for all the reviews and info in the forum!
