I'm driving myself crazy the last few days reading reviews and other links on the forums about each of these IEMS but I'm just getting myself more turned around.
I had a set of M1's that I liked a lot but had an unfortunate run in with the washing machine, so I'm currently using my backup set which is Sennheiser 475. I'm not a big fan of these Sennheisers so I'm in a hurry to replace my M1's.
I'm looking for something with good sound isolation, I listen mostly at work, at the gym, or while remodeling my house. I like bass at times but I'm not the type that wants it all the time because it can end up giving me a headache. Also I'm generally listening to music on my razr smartphone (root with Beats drivers).
How powerful is the base on the FX3X? Headache inducing?
The M5's are described as "allowing you to hear each instrument" - Does that mean they are the cleanest of the 3 for vocals? Does it also mean you get less listening fatigue from them?
The M2's have the highest price tag, are they the best all around?
I'm open to getting 1 set for the gym (probably the FX3X?) and another set for work, but I don't want to buy all 3!
Secondly, is there any benifit to buying a FIIO amp with the headphones? I'm not sure if it's a waste on razr smart phone streaming pandora...
Guidance would be appreciated!
