Good packing and build quality. take note it some time to hear bass for the earphones, because you need some time at least few hours for pot earphones. tests wire profmance with Samsung s8+, lag v30, iPad 6 generation, sound blaster G5, Meizu dac, realtek alc5686 and ibasso Dc03 all make good volume for the earphones. bluetooth test with Qualcomm QCC5125 ( brought separately), again very good volume. to conclude very good product highly recommend.
blue tooth for the headphones.
Order shipped very quickly. Good seller. Thank You!
