I sleep with my GR07's, like a baby.
Not necessarily, but being strictly over ear and having adjustable nozzles, the GR07 does take some adjustment and getting used to initially. There is a minor struggle every now and then to get them in place, but once they are there, they disappear (for me anyway). Being adjustable, though, means that if the nozzle is moved, you'll have to re-adjust it again to your preferred position. I've personally found silicone tips (stock and genuine sony hybrids) to be the best fit and most comfortable for long listening sessions, but either way you have to get a good seal for the best sound. I think the overall presentation really comes together after about 50-75 hours of use.
I think it varies from person to person, IEM to IEM - some people have slightly different shaped canals in each ear, so getting a perfect fit with universals can be hit or miss. I wanted to comment that I've also narrowed my next IEM down to the 5.0 as well, and recently it's been noted that it relies a good bit on the right tip for optimal fitment - I still think it will varies for everyone, though.
