Hi. I own Etymotic Research ER4SR in-ears, with standard 3.5mm termination. If I understand correctly, the SR25's balanced output is more powerful. Etymotic is now carrying balanced cables - at a pretty reasonable price. I'm not very technical & don't really understand the relationship of impedance, sensitivity, power etc. Are the Etymotic's are considered 'hard to drive' with an impedance of 45 Ohms. Would it be beneficial to switch from SE to BAL with these earphones? What *might* I expect? Also - if anyone can direct me to a site with layman's explanations of some common specs, terms, etc for headphones & DAPs- much appreciated! Thank you!
You are going to get varying opinions here, but the reality is that you don't need balanced for the Ety's. Balanced will play louder, but I can't imagine that you need more volume. Etymotic will be happy to sell you a cable, though... And yes, the ER4SR are somewhat harder to drive than some IEMs but the SR25 should be more than capable single-ended.
