Burn in earphones?

Is it necessary or good practice to expect JVC earphones to improve after some period of time (burn in). If so how long?

No. Please just burn them.
A good seal will have more impact on most IEM's than break-in. If you are having issues I recommend starting with the tips. If you dislike a headphone after the first 10-20 hours you probably should go with something else.

Mechanical things (transducers included) do typically have a break-in period. With earbuds and headphones, I wouldn't worry too much about it. Just use it normally and eventually they'll break-in. There was only one time where I recall something sounded noticeably a LOT better after breaking-in, which was the Campfire Audio Solaris. But then again, Ken Ball himself recommends breaking them in (and it's stated online), and I consider that an exception rather than the norm. Usually, if you don't like the way it sounds when you take it out of the box, break-in is not going to change your mind. Now, NOS tubes need time to burn-in because of the impurities needing to be burned off (accumulates by sitting there unused), but again, wouldn't worry too much about it.
