I'm looking for a truly silent practice solution and have been considering getting a set of IEM's. I'm drawn to IEM's for several reasons: They look to be light weight and comfortable enough so I cold wear them for a few hours if I wanted. I have found that over the ear closed back headphones are bulky, heavy, and clamp my head enough to give me a headache if I wear them for more than an hour or so. There are some models that are geared towards neutral frequency response which is attractive because then I could transition between my Adam A5X monitors and the IEM's with minimal tweaking. It seems that most over the ear closed back headphones have unnaturally hyped bass response and a very small sound stage. They could be useful in a live setting if I end up in a group that goes the IEM route. I have a few questions: Is going custom worth it? I'm willing to spend the money if it means having a more comfortable fit or better audio quality, but it is a big cost increase. Is there a model or brand that you think is king of the hill? I've seen people recommend Westone, Sensaphonics, 64Audio, and Alclair. The max I'm willing to spend here is $1,300. My two biggest criteria are comfort and sonic neutrality. I've read statements that more than 3 or 4 and you can't really tell the difference beyond that. Is that true in your experience? I'm aware that for live use I would need to get a transmitter and other outboard gear, but that's not a concern for right now as I would be strictly using these at home in a wired setting.
