We used to admire the little boys who build sand castles on the beach. It took them hours to carefully finish each door, gate, wall, to attach each snail shell to the project. But just a wave comes, the castle is gone. The miracle thing is, in the next morning, other castles will be established again. With many years’ experience in the audio industry, our team realize that we can do much more than we assume if not being afraid of failure.

We are all audiophiles and beauty fanatics here in Joinhandmade. We have concerned more than hundred of drafts and sketches in this journey because we strived to develop an earphone that pushes the limit of beauty and functionality. Smartphone, tablet, wireless internet and other high-tech equipment have almost got human online 24/7. Perhaps this has made people lose concentration, which affects our creativity. Therefore, making and using handmade products are the alternative ways for us to escape from that virtual world, to perceive the real world with high concentration and thereby maintain the inherent creativity of mankind. In the world of technology, of modern and mass production, more and more people desire to own something unique and having some “human” in it. That’s what handmade gifts are made for, isn’t it?

“Unlike other mass production earphones manufacturers, Joinhandmade created a very unique headset. From the out-look, design, to sound quality, all show the care and passion of the team. To produce finished earphones, each stage of processing is taken carefully and delicately, just to create stylish and unique handmade earphones for users.”

Charles Bonn (Head-fi)

“It’s not only a good earphone, but also a stylish jewelry. This “made in Vietnam” earphone achieves both sound quality and unique imprint design. thank to its handcraft process.”
