As to the sound, personally I usually use it to listen some Language courses during strolls after dinner. Some times listen some female voice. It is enough for me.
Suggest you to wear it with sponge earmuffs, it would be more comfortable.
Personally, I think the real target of AM90 is BRING PEOPLE A B.A. IEM AT THE MOST AFFORDABLE PRICE. At least, people could only pay RMB168 to taste how does balanced armature IEM like.
