I currently have a stationary system based on the Stax SR-009 and I am fully satisfied. I have recently acquired a SRS-002 set, but for maximum portability i'm very curious to know something more about the custom IEMs, which I only read good things.
I have no experience with them and I have many doubts about how many drivers are the necessary or ideal for a good configuration, sealing capacity, brands and models..
Some of my questions are:
What are the main differences between the CIEMS and the IEMs?
How is the request? I do not understand very well if they are personalized by the customer based of the type of morphology of the ear canal.
What are "custom" refered? Drivers? Sealing caapacity?...
Are they difficult to drive? Do I need a dedicated amplifier? I would like to use with an iPhone 4S
Are they comparable to a Stax SRS-002 set?
Thank you for your attention and help...
