Testing and Quality Control is Something We Take Extremely Serious!

At Rock Jaw Audio, we take pride in products like the T5 Ultra Connect and the Alfa Genus V2. We want to make sure that the product we put on shelves and send to customers is the best we can achieve. To do so, we take a long time to bring a new product to market, and any new product goes through a lengthy prototyping stage, as well as a comprehensive testing programme to make sure they meet our high standards.

The Rock Jaw Audio product line has always been known as being British Engineered, and we stand by that. Product development starts in the UK and products are only put into production once they get the go ahead in the UK. New products are developed for roughly 12 - 16 months, from sketches to CAD drawings all the way through to driver selection and beyond. We put our new products under the microscope during their development to ensure that all details are 100% before we go any further. During this 12 - 16 month period, they go into quality assurance around 9 months, and are tested for a further 3 - 5 months before we put them into production and then put them up for sale. 

It's important to us to make sure that our customers get the Rock Jaw product we know we can deliver, and testing products rigorously is how we make sure things meet our extremely high earphone standards. 

Why our tuning filters actually work.

One of the big reasons that customers keep on coming back to us and recommending products.  We explained what each of these do in an earlier post, and while you might think these are gimmicks, this post is here to explain why that's just not true. When we decided to offer something above and beyond the usual earphones on the market, we settled on the tuning filter system to offer some flexibility and to appeal to a wider audience. 

It's arguable to say that the driver configuration inside (the driver) can't be changed too much through the use of a filter, but subtlety is the key here. After all, a little treble can mean much more detail to one person, but sound too harsh to another. Which is exactly why we provide three options in the box. When a customer purchases a pair of earphones like the Resonate from Rock Jaw Audio, they get flexibility and choice. Everyone hears things the same and for this reason we chose to develop our tuning filters to be as effective as we can.

Our tuning filters are precision engineered and CNC milled from the same aircraft grade aluminium we use in the shells for products like the Alfa Genus V2. On top of that, each of the tuning filters feature a rubber gasket to ensure an airtight seal, which both ensures a quality sound and ensures safety, too. All of our tuning filters screw in with ease and are super-easy to change, while our packaging gives you an opportunity to keep your filters safe when not in use.

A gimmick is something that attracts attention, something that feels part of a fad. Our tuning filters are anything but an attention grabber. They set our product aside from the rest and they offer a little more value, while ensuring that the set of earphones you've paid for suit you.  


Here at Rock Jaw Audio, we've been creating quality audio products for some time now. We know, however, that having the product isn't enough these days. Consumers expect quick shipping, easy ways to purchase the product and the knowledge that their new item is going to arrive safely. 

When a customer chooses to purchase a Rock Jaw pair of earphones as their next pair (which we're super thankful for!) their order goes through a number of stages. Obviously, the first step is adding the item to your basket and checking out, which by the way is super-secure that's to our choice to use a similar online store to millions of others online. After that, the order is passed to our warehouse team which will select your chosen pair of earphones, check to see that all ear tips and accessories are accounted for, test and package carefully. 

Shipping time varies depending on where in the world you are, although one thing doesn't change; shipping is free worldwide with Rock Jaw Audio. If you're in the UK, we'll provide you with free tracked delivery and if you're outside of the UK we'll send your new pair of earphones to you via recorded international mail. All orders go tracked directly to your door.

Once your new pair of earphones reaches you, what you do with it next is up to you. We hope, however, that you unbox them, plug them in and give your favourite music a listen. Selecting your perfect tuning filter.
