T3™ In-Ear Monitor

 A decade of heritage
The T3 is our original in-ear monitor built with a single lightweight driver in a canal-mould shell delivering the full dynamic range of sound from a clean, simple and discreet package weighing in at only 13 grams. First manufactured in 1999, the T3 has been delighting audiophiles and performing musicians alike for more than a decade giving people the freedom to enjoy sound just as they want to hear it without interference from outside noise. The T3’s latest incarnation offers up the most dynamic and accurate driver in its history that gives you reference quality sound from a tiny package that keeps the T3 as discreet and lightweight as possible without compromising on the substantial soundstage that monitor users demand.

Creating clarity
The isolation provided by a custom-fit earpiece brings not only safety benefits but allows lower listening volumes, even in noisy environments, which means you get better sound and a much more comfortable listening experience. The T3 is manufactured from soft medical grade silicone which warms to body temperature in just a few minutes creating a snug, airtight fit that makes them far less noticeable to the wearer. Because the earpieces are flexible they are able to maintain a perfect seal at all times, even during vocal performances when the shape of the ear canal changes with the movement of the jaw.

Continuous innovation
Over the course of the last ten years no aspect of the T3 has stood still. The ACS spirit of innovation has meant that the T3 has been tweaked and improved every year of its life to give us the product that many people still swear by today. Improvements to the silicone, the build method, the driver and the cabling have kept the T3 at the forefront of cost-effective in-ear monitoring and this innovaton continues today. Making sure that we use the right cable to deliver your sound is as important as every other aspect in the design of our monitors so we make sure they are just as well thought out. Starting with the best conductive core we then add Kevlar threads for strength and flexibility so that we can be sure you’ll get the performance you demand. Each cable is sheathed with a special finish that reduces the transmission of friction noise to the earpieces so there’s as little interference as possible.  The cable is then clamped at the Y divide with a custom pressed lengthened binder to give it extra strength where you need it most. Finally, each cable is finished with our custom-moulded right-angled plug offering high levels of resilience as well as quality with a gold-plated 3.5mm connector and iPhone compatible shoulder design.

A personal finish
It’s the finishing touches that make every one of our hand-made monitors completely unique from a choice of cable colours to a selection of bespoke silicone finishes. Every monitor can be laser etched with lettering of your choice.

Please note - ACS products require good deep impressions in order to create a seal in the ear so it is important there is no wax block in the canal that will stop the audiologist from taking an impression. If you think you may have a wax build up, please visit your local GP for a consultation before booking an appointment with a dealer. You may be charged a fee if the audiologist is unable to take an impression.

Where can I buy ACS products?

ACS products are available from a nationwide network of Audiologists as well as directly from us at our offices in Banbury. You'll need to make an appointment to have impressions taken which will then be sent on to us to allow us to manufacture your custom-fit products. To find your nearest Audiologist see the complete list on our Find A Dealer page. Please note that production time is always dependent upon orders received.  The skills and experience involved in making our hand-crafted products are not acquired overnight so employing more staff, whilst increasing our labour force, does not bring an immediate reduction in production time - please bear with us in times of increased demand for our products

Since the charity’s foundation in 1911, it has grown to be the UK’s leading deafness charity, supporting more than a quarter of a million people each year and running the world’s largest donor-funded hearing research programme.
