How do I order a custom earpiece for my earphones?

Click on the blue Shop Now button below the product offered. If placing and order for two or more sets of earpieces, let us know if the earpieces are for the same person. If for different people, please specify the name and color for each person in the comment section before check out.

Once your order is received, we will ship a set of impression kits to make an impression of each ear (or in the case of deep impressions, we will email you a Lab Order Form, see deep impression advisory). Mail the completed impressions to our lab using the postage paid mailing materials or to the address at the bottom of the lab order form. We will use your impressions to make a reverse casting and return to you a set of custom made earpieces that will fit on your earphones and are guaranteed to give you the comfort and convenience you have been looking for.

Earpieces can be ordered in a wide variety of colors. If no color is selected the earpiece will have a variable tan color. (The material does not cure perfectly clear.) There is even a glitter option for that personalized touch.

Your comfort is guaranteed, or we will
remake your earpiece for free!

I just wanted to say thank you! I just received my ear pieces and they really are amazing. I am surprised by their comfort and stability. They have made the sound quality of my MP3 player much more enjoyable. It is also great to not have to worry about my headphones constantly falling out! I have already suggested Avery Sound to many people! Thanks again!

So I got the new Sennheiser CX 985 earpieces, and what a wonderful experience! They are comfortable and sound fantastic. Thanks for suggesting the deep molds. The first thing I do when I get new earbuds or a Bluetooth headset is talk to you. I am bit spoiled - the custom earpieces are comfortable and make even cheap headphones sound like expensive ones. And I tell my friends to do the same. OK, now I have to have these for my LG HBS700 bluetooth headset. How much to make a set from these molds?

I just wanted to thank you for my new earpieces. They are really excellent! Now I can listen comfortably to all my favorite recordings. I can even fall asleep with them on. And thank you again for your high quality production standards and your attentive, personal customer service! Best wishes.
