The are very well made. I love the magnetic lid close and set of the buds in the case. The sound is amazing, much more base than I expected with great highs. I am very happy with my purchase. For me, the only negative is the ear cup material. I have small openings and use the smallest set but the right bud come out easily. I am curious to see if my free gift foam replacements remedy this. Overall I am very pleased with this purchase.
My 1st earbuds as an old timer my hearing loss on higher frequency was interfering with my foreign language lessons. These have helped a lot. The product design and execution just blew me away! So now I've bought the Jlab studio pro and headphones too. Only one small improvement would be if they added a ridge around the edge of the plastic body to help catch a fingernail on to help leverage the bud out of the case. I put a tiny piece of bandaid to help get some friction.
