I'm new to the forum and relatively new to the Hi-Fi headphone world. My favorite set of headphones, the Etymotic Research ER6i just died on me (the wiring in the plug is broken) after almost 7 years of loyal service. I'd try wiring a new plug in but, this hasn't really worked out well for me in the past. I'm thinking it's time to pick up another pair of comparable headphones and am tempted to go back to Etymotic, as I really love their sound quality and unmatched (as far as I know) noise cancellation with the flanged ear tips. I was wondering if anyone here could help me figure out which of the newer models are comparable to my current set.
I'm looking into the mc3 model (about $70 on amazon) or the hf2 model (about $110 on amazon). The only differences I see in the specs is that the hf2 have a "High-performance balanced armature" and 105dB sensitivity vs. 100dB for the mc3 with a "High-output 8mm neodymium moving coil driver". To be honest, I have no idea what they mean by hi-perf. balanced armature and how that compares to the driver in the mc3. My question is, does anyone here have experience with the models I've described (or the mc5 and hf5 which I assume are the same models but with no mic and/or volume controls, please correct me if I'm wrong). If so could you please give me feedback on how they compare, and if the hf2 are worth the extra $40. Furthermore could anyone please confirm if either the mc3 or hf2 are the comparable models to the ER6i or if I need to step up to the more expensive ones.
Thanks in advance for all your help.
