Decibullz Custom Molded Earplugs Review

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

This is hardly a consumer tech product, but as I get older, I have started to get some tinnitus and have become increasingly concerned about hearing loss later in life. You don’t really care about loud pubs and clubs in your 20s, but I can assure you that you won’t feel the same later in life.

On top of being concerned about my hearing, I sleep terribly and wake up with the smallest noises.


Decibullz Custom Molded Earplugs Review1

I have bought various well-reviewed earplugs off Amazon, the last being EarPeace Concert Ear Plugs.

They work well, the clear silicon is reasonably discrete, and they have a filter which goes inside them. You can then filter out different levels of noise, and this is perfect for pubs and clubs because you can reduce the harmful noise while still (just about) being able to hear people.

However, the big problem I have with them is the panic that settles in when you struggle to get them out. This is amplified when I am drunk. You can get earplugs with a cord attaching them, which is what I should get real.

Therefore, the main appeal of the Decibullz to me was that the moulded design means that they are never getting lost in my ear canal (unless the tip comes off).

That’s not supposed to be the selling point of Decibullz, but it was for me.

What these actually do is offer superior noise-cancelling thanks to an improved fit due to them being moulded into your concha.

These claim to offer 31dB of noise reduction but this is when you use the foam tip instead of silicon. They don’t seem to provide the data for performance with the silicon tips.

In comparison, the EarPeace I have provided 17, 20, and 26dB of cancellation depending on the filter. Decibels are a logarithmic number, so 31dB is significantly higher than 26dB. The downside is that Decibullz have no filter, so they are not really designed for music/pubs where you might talk to people.

Moulding Process

The moulding process is quite simple, and there is a YouTube video to guide you. Basically, you attach the silicon ear tip to the earplug and drop it in a cup of boiling water for a few minutes. When you take it out, wait for it to cool down, insert the earplug into your ear and mould it for a secure fit inside your concha (ear dome).

If you don’t get the fit quite right, you can redo the process.

Performance in loud environments

I have predominantly used this with the silicon tips mainly used in pubs and with live bands. They have worked well, doing exactly what I want, making the noise bearable and avoiding next day tinnitus.

I’d say they are easier to insert than standard silicon plugs, the moulded design means I am not messing around trying to find the best fit.

I wouldn’t say the performance feels significantly better than the cheaper none moulded silicon tips. However, logically it makes sense that these would provide better protection in louder environments.

The main thing is that I don’t have that sense of panic when I drunkenly struggle to retrieve the earplug in my ear.

I had hoped the hard plastic cap would make it easy to remove them, but I found that this is quite difficult to grab. However, with the moulded shape, it is easy to push back your concha a little and grab it from the moulded section.

Using while sleeping

I have tried these earplugs for sleeping and had OK results. The main issue you have is that the external cap and mounting for the silicon plug are hard plastic. Sleeping on this is going to be quite uncomfortable if you are a side sleeper.

I ended up just using one plug, and the pillow provided an adequate amount of noise cancellation.

More importantly, I wasn’t worried that I might roll onto the earplug and force it too far into my ear!

Price and Alternative Options

Decibullz are available from Amazon for £30, and they appear to be the best-reviewed earplugs on Amazon. They are also one of the most expensive.

The EarPeace Concert Ear Plugs I have are £21

Loop Experience looks good as they have a nice big loop that sticks out of your ear for easy removal, the loop itself has a hole with a filter in to let some sound through, so you can still experience music/talking. These only provide 18dB noise cancelling, or you can get the Loop Quiet which does 27dB.

Foam plugs are good if you don’t mind the disposable nature and ugly looks. You can get 60-pairs for just a tenner, and these provide a massive 38dB of noise reduction.


For me, the Decibullz work well. They are effective for loud pubs and live music. They are not as discrete as clear silicon earplugs, but they are easier to insert and remove.

You can’t put a price on your hearing, and if you regularly expose yourself to loud environments, you definitely should invest in a good quality pair of earplugs, regardless of the price.
