Headphoneus Supremus
He is a one-person business. Actually it is probably more like an enthusiast hobby for him (I don't think it's possible to make a living from building custom earbuds). He runs his business from his Facebook page and that is the way to contact him. You can ask if he is willing to meet with you in Singapore.Thank you example if i can travel to Singapore. Do you know where to try his product or contact to buy from him ?
If you haven't seen it, there is a Blur earbuds thread and it has contact information:
