Decibullz Custom-Fit Bluetooth Wireless Earphones

What makes these earphones unique?

The Decibullz Custom-Fit Bluetooth Wireless Earphones utilize earpieces that are made exactly for your ears, by you. The earpieces are easy to mold to your ears and they provide you with earphones that are very secure in your ear and offer excellent noise isolation.


I’ll start out with what was included in the packaging with the Decibullz Custom-Fit Bluetooth Wireless Earphones. The box includes Decibullz Wireless Earphones, 2 Custom Molds, S,M,L Silicone Ear-tips, Protective Earphone Case, Micro USB Charging Cable, a Cable Clip, and instructions. The protective earphone case has a nice zipper and two interior pockets, perfect for storing your silicone ear-tips. The cable clip is an optional accessory that can be used to tighten up the slack in the headphone cable behind your neck.

Making Your Mold

In order to get the most out of your Decibullz Custom-Fit Bluetooth Wireless Earphones you will need to spend around 5 minutes making your custom molded earpieces. The custom molding process is very simple. Here are the steps that I followed:

  1. Heat up water in a cup using your microwave
  2. Attach a silicone ear-tip to each custom mold
  3. Place one custom mold into the hot water and let sit for 5 minutes (I put both molds into the water at the same time, but this is not suggested)
  4. Remove the custom mold from the hot water using a metal spoon and let cool for 30 seconds
  5. Snap custom mold on to earphone
  6. Place the custom mold with the earphone into your ear and gently shape the mold into your ear with your finger. Let sit in your ear for 5 minutes
  7. Repeat the steps with the other custom mold, in your other ear. If the custom mold doesn’t turn out as well as you hoped, follow the steps again to remold.

These steps are shown here in this video made by Decibullz:

Here is a video made by myself showing my experience with the custom molding process:



These earphones are the most comfortable in-ear earphones that I have ever used. I barely even notice that they are in my ear because there are no uncomfortable points of pressure created by the earphone.  Thanks to the custom molding, these earphones really stick in my ear no matter what I am doing. The custom molding works significantly better than any other mechanism that I have ever seen to keep ear-bud style earphones securely in your ear. No matter what you are doing, they simply stay put in your ear.

Noise IsolationDecibullz Custom-Fit Bluetooth Wireless Earphones

If you are looking for earphones that will allow you to listen to your music in peace, then look no further. The Decibullz Custom-Fit Bluetooth Wireless Earphones cut out almost all noise around you. This is great when listening to music at the office, while mowing a lawn, while riding a motorcycle, or any other time when you want to cut out background noise. However, one situation where I recommend taking caution is when exercising on a road. These earphones stay in your ear excellently while doing most activities, but you can’t hear any of the cars or people around you.

According to Decibullz support website these earphones provide a NRR (Noise Reduction Rating) with silicon tips of 24, or 31 if you use foam tips. I decided to put these to the test using the provided silicone ear tips at a shooting range. After shooting various hand guns and rifles for about 2 hours, I was able to walk away with zero ear pain. These earphones, surprisingly to me, provided more noise reduction than my big over-ear earmuffs that I typically use while shooting. I can only imagine that these earphones would provide even better ear protection at a shooting range if I was using the foam tips and the percussive filters made by Decibullz.


One of my favorite features about these earphones is the fact that they are wireless. I hate having wires dangling from my head that are likely to get caught on things. With the Decibullz Custom-Fit Bluetooth Wireless Earphones simply pair them with your device using Bluetooth and never worry about tripping on cables again.

There is an inline earphone controller a couple inches down from the right earphone that has 3 buttons, a microphone, and a micro-usb port. These 3 buttons can be used to control volume, skip songs, play/pause songs, and answer/end calls. When making calls, you will never have a complaint with these earphones. The microphone works great, and the noise reduction of the custom molds provides you with no problems when trying to hear the people you speak with.

The micro-usb port can charge these earphones in 1 hour. With a full charge, these earphones will provide 3.5 hours of music playing time, 4.5 hours of talk time, or 150 hours of standby time. Most of the time when I listen to music, I don’t listen for longer than 2 or 3 hours, so these seemed to always last long enough for me. If you absolutely need your earphones to last longer than these then I would recommend the wired headphones from Decibullz found here.


I love these earphones and highly recommend them to anyone. Thanks to the custom-molded ear pieces, these earphones are very comfortable for people with ears of all shapes and sizes. They provide excellent background noise reduction helping you to be able to clearly hear your music or your conversation. With the ear pieces custom molded to your ears, you will never have to worry about these earphones staying in your ear. Go buy yours today from Amazon.
