I find it a bit bothersome that most custom IEM makers don't cover the cabling under the warranty because braided cables have a tendency to start debraiding regardless of whether or not they have been abused.
crappyjones, can you diagnose why the left earpiece is cutting out? is it because of the hardware within the earpiece or the cable (swapping the left and right cable can determine if it is the cable or the earpiece itself) also, were the phones regularly cleaned of earwax?
I actually bought a pair of sth840's from electronics expo, shipping was fast, no issues. Though others have had issues with receiving a keyboard/mouse set when they ordered a pair of $500 denons
