I am switching from headphones to IEM's and need advice. I'm going to get either an entry level CIEM (CTM-200) or mid-level IEM (Heir, Westone, SD-2) I have read tons of reviews and posts about CIEM fit and comfort, but I need opinions based on my listening habits. I listen for 30 to 45 minute intervals, several times a day. For those of you with CIEM's, would you consider it too much of a hassle to put in your CIEM for that short of a listening session, several times a day. I have some inexpensive IEM's (VSONIC) that are no hassle to put in and remove, but I need input on CIEM's. Thanks in advance for any input.
