as you like, but Z5 excellent headphones that I had to listen to.
They are good, but was looking for better seal and next level of sound. Can't listen properly even with just a small fan in front of me, or while taking a train. Only in a quiet room can I hear small subtle difference of the Z5 vs my B&O H3 IEM, which is not what I would like to use the IEM for.
JH has improved their top end alot, much better than my JH16pro, and much much better than my Z5 obviously.
BTW, the B&O H3 anc is designed with a 10.8mm dynamic drivers, and it has very very similar sounding as the Z5. Under usual environment, I can't tell a difference between both.
