I grabbed the Soundmagic E10 refurbs that were either listed here or on the deal discussion thread that were $14 for my son. He's hard on IEMs (and he tries to take care of them). So I have to watch for bargains. He likes the Bass Colours I got him, too.
HE-400s are weighty. That's the only comfort issue really. And if one has a bunch of other headphones and IEMs (like us--lol), then it's easy enough to use switch to another pair after an hour or two if the weight becomes a little much. They really are some excellent headphones, although lately I have enjoyed some K612 Pros for their more neutral sound and bit better soundstage (and yes they are more comfortable).
I'll have to remember the bass colours the next time my son ask for new IEM's. Gives me a good reason to hear them
Yeah the weight of the HE-400 combined with my very small head makes me worried. TBH I really hate having great sounding headphones with lack of comfort. They don't get the amount of use they deserve and I cannot let go if them because I love the way they sound when I eventually listen to them.
I actually had a hard time deciding between the 612Pro and the Q701. I went to by the 612Pro in a store but they were sold out and when I got home to order on the web I found the q701 for similar price and went with them due to the detachable cable.......
