Review: Decibullz – Custom Molded Bluetooth Earbuds


Decibullz earbuds are a game changer for secure and comfortable fit that stays fixed to the shape of your ears uniquely. Earpieces can and should be molded according your own shape of the ear.

The whole process takes less than five minutes. Just heat the earpieces in the water and put in your ears to mold it according your ear shape. If you are not happy with the result first time, you can repeat the process multiple times.

What about the earbuds and quality? Here’s two most important factors: comfort fit and and sound quality. comfort and unique fit with amazing sound isolation is a double win for this product.

On the other side – sound quality is “OK”. Voice calls and audio books works great, but you would feel a lack of basses and full spectrum of music sound.

Decibullz also offers custom fit wired earbuds that fit the same thermo-fit earpiece and come with standard 3.5mm plug for a lower price than wireless ones.

To sum up, if comfort, unique fit and style is the priority to you, these Decibullz bluetooth earbuds are hard to beat. Earbuds are amazing on sound isolation and accompanying during workouts. Though, sound quality is good, but not amazing for the price.
