I would appreciate your recommendations for portable headphones for classical, something that has as detailed sound as possible.
I'be been using VSonic GR07 for several years, but I like it less and less. Its highs sound too harsh to me especially with solo violins. Also, I would like to avoid in-ear design: I can never get perfect fit even with a dozen of different tips that come with GR07.
Headphones will be plugged into an iPhone directly, no amp.
