DUNU has equipped the EST112 with a quad-driver triple-hybrid driver configuration on both sides. The pair features a powerful dynamic driver unit with dual-sided beryllium coating paired with a premium Knowles BA unit and two high-performance Electrostatic drivers. The EST112 is the first pair from DUNU to feature a triple-hybrid driver configuration.
Powerful Dynamic Driver Unit With Dual-Sided Beryllium Coating:-
DUNU has equipped the EST112 with a large 13.5mm dynamic woofer. It has a dual-sided beryllium coating. Its diaphragm is thicker with a finer & regular grain pattern. It helps bass and lower midrange frequencies maintain their palpable texture and separation with ultra-low distortion ratings.
High-Performance Knowles Balanced Armature Driver:-
DUNU has featured a high-performance balanced armature driver from Knowles in the EST112. It handles the mid-high frequency response in the pair with a transparent and reference response. The pair produces lively and engaging vocals with high-resolution clarity.
High-Performance Sonion EST Drivers:-
Long gone are the days when EST drivers were only being used in high-end headphones. The technology is advancing at a rapid speed with its implementation in many flagship IEMs. DUNU has implemented two high-performance EST drivers from Sonion(a highly renowned audio driver manufacturing brand). They present a smooth, elegant, and well-detailed high and ultra-high frequency response with the EST112.
All-new Lightweight & Elegant Aluminium Alloy Shell:-
DUNU has designed an all-new shell package that encapsulates the re-engineered driver circuitry. The ear cavities are made with a high-precision machining process using lightweight and durable aluminum alloy material. They are finished with scratch-resistant gunmetal anodizing and feature polished stainless steel faceplates for a simple yet timeless design.
Silver-Plated Copper Litz Cable With Patented Quick-Switch Modular Plug System:-
DUNU bundles the EST112 with its premium DUW-02S cable. It is a high-quality Litz braided silver-plated copper cable with DUNU’s patented Quick-Switch modular plug system. Apart from the standard 3.5mm single-ended plug, the package includes 2.5mm and 4.4mm balanced termination plugs.
When Taron and Andrew Lissimore started headphones.com, they wanted to create the headphone store they wished existed. As headphone enthusiasts, they wanted a store with 365-day returns.
So they decided they were going to try to make 365-day returns work - no matter how ridiculous it sounded to their wives.
Years later, they're still doing it, and their wives still think they're crazy.
So take some time to get to know your new gear. We want you to enjoy your purchase for years, not just a few weeks. If you're not satisfied, you can return items in like-new condition for up to 365-days.

Return Policy Abuse
In order to provide a 365-day return policy, we need to take abuse seriously.
We monitor a buyers ratio of purchased to returned products. If it exceeds an internal threshold they will no longer be allowed to place orders with Headphones.com. This includes customers who spread returns across multiple accounts.
We made our return policy to help you find gear you feel great about for a long time. Most people use it exactly as intended. We don't want the handful of people who attempt to abuse our policy to ruin it for everyone else.
If you paid with a cryptocurrency, the returned amount will be equal to the USD equivalent of your payment on CoinGecko.com at the time the refund is processed. The return will be made in the currency of your original order.
After You've Made a Return
Each return is inspected at our warehouse. During busy times these inspections may take a few extra days.
Refund or Credit
We will notify you by email when your refund or credit has been processed. It may take a few business days for a refund to appear in your account. This is determined by your financial institution.
If you still have questions, please email firstname.lastname@example.org and an advisor will be happy to help.
One of the key things we pride ourselves on is our customer service and one of the most important aspects of our customer service is getting you your product on time! But not only do we want to get it to you on time, we want to make sure we are using a reliable courier so the experience for you is the best possible. That is why we ship all of our orders with FedEX.
While couriers like USPS are tempting because of their low cost, we have found that they are not a good experience for our customers. Nobody wants their package to not be delivered and then have to spend an hour on hold with the local post office trying to get information. To that end, all of our packages are shipped signature required with FedEX to make sure your package arrives in your hands safe and sound and if there are any issues, your time isn't wasted.
However, if you are looking to ship to PO Box or APO address, we can definitely accommodate your shipping needs!
