I bought this product because my friend bought it and recommend it to me. It sounds way better than you might expect from IEMs at that price. The materials used are great. Execution is also very good. I recommend for everyone who needs good earphones for very low price.
I bought this product becouse my friend bought it first and told me: "This is best earphones I ever had." So i don't wait more time and I bought a pair for me. Shipping was verry fast (+/- one week) and free! The sound is pretty amazing for this price. All sequences play in the ideal harmony. This earphones is better than AKG K370 but much cheaper than it. AKG cost 80$, JBM cost 14.50$. JBM had better sound and much better price so the choice is only one. I chose JBM, now is your time to chose.
