Review on Decibullz Custom Molded True Wireless Earphones - Premium Noise Isolation, Bluetooth 5.0, Sweatproof | Buy Now with Charging Case and USB-C Cable! by Jessie Ritchie

I had some doubts about that. I didn't even dare to dip the molds in boiling water. Surprisingly everything works! The custom fit is perfect. The connection is difficult at first, but be patient and it will come to you. As you move away from your device, they appear and disappear, but stay where you are and they disappear. The sound is great, including volume levels, but I'm thankful for the airtight seals. The battery is standard +, 3 - 3 1/2 hours is what I get. I'm happy with them now that I've gone through the trial and error phase. I'm not sure if they cost $100. Maybe $75.
