I bought this earphone as the birthday party to myself. unfortunatelly, the Australia post lost my parcel. I ran to the post office for more than three times, but all the answer I got was the parcel was delievered. but I didn't get it. I was so upset, coz it's a lot of money for a student, and I want the earphone so deadly. after I connected with Thomann's stuff, they told me dont worry about it. They will investigate the issue and give me feedback. when they found the parcel was lost, they sent me a new one for replacement. this earphone is sooooooooo good. it's perfectly suit for my ear, and the bass is enough for me, maybe a bit more will be better. the midrange is well-positioned. and the top end is a bit too much for me. but i think after burning in. it will be much better. Thanks for all of your help. Thank you Cristina.
