A little headphone store filled teddy bears that has a collectibles of headphones, earphones, portable amplifiers, digital analog convertors (DAC) and many other fun stuffs!
I tried the JH16 and I dare say it was the ultimate in IEMs.Unfortunately the fit wasn't right so I won't put it down as comfortable.
JH16 is a custom IEM, you'll get yours customized just for your ears ^^
Hie, chen, that JH16 is other people's ear, so it is naturally not comfortable to you. You need to custom make the earmold, personalized.
