Product Details

A completely fresh approachACS T2 Triple Driver IEM

The T2 represents a completely fresh approach to dual driver in-ear monitor design with a complete ground-up redesign. The all-new dual driver design and custom crossover bring improved range, clarity and accuracy to the T2 giving you an in-ear monitor with power and breadth that are ideal for the live environment whilst keeping your sound accurate enough for mix monitoring and intricate vocal performances. The T2 brings new depth and sparkle to your sound and to your performance.

The same accommodating approach

Just like any ACS product, the T2 is manufactured from soft medical grade silicone giving you a fit like no other earpiece. We use the softest material in the industry to give you unparalleled isolation in the most demanding environments with a consistent seal at all times and, because your earpiece can flex with your ear as you move or sing, your monitors stay comfortable without fatigue or irritation. In addition to comfort and isolation, using silicone allows us to seal the speakers into the mold and take control of their acoustic environment, this means we leave no room for the shape of your ear to affect how your monitors will sound or for your drivers to misbehave so they sound just as our technicians intended every single time.

So much thought into such a small object.

ACS in-ear monitors are designed and produced according to some simple principles that we think help us to focus on what’s important rather than just chasing the pack. Our earpieces are flush and discreet in the ear, we don’t just throw more drivers into the mix in the hope that it will make the monitors sound better, particularly if that means delivering ear shattering volumes. We pay attention to every aspect of the T2, from the 3.5mm plug right to your eardrum to make sure it’s performing as it should and we don’t do as others do if we don’t believe it is right. Based on our proprietary cable design, the T Series offers removable cables featuring one of the smallest and most resilient connections around. Keeping the connector as small as possible means that we can keep the cable discreet and mounting the socket right in the silicon means your cables will stay put in performance but come loose if the cable is pulled from the ear minimising the risk of damage. Not only that but by simply moving the pins from the plug on the cable to the socket in your monitor we’ve minimised the chances of damage to the cable even when it’s not connected. With the pins in the socket sunk into your earpiece there is no chance of them coming to harm and with no pins at the cable end at all it’ll take a lot more than a size 13 Doc Marten to put you in need of a replacement.

The home of audio innovaton

In choosing ACS you’re choosing a refreshingly different approach to innovation. Our products have been designed and refined by everyone from our customers and sales people to our lab technicians and acoustic engineers so you can benefit from all of their combined experience. With a dedication to leading rather than following the field, ACS has set the bar for second generation silicone in-ear monitor design leaving others replicating our first generation breakthroughs.

Comments from Mal Herring, a customer that bought the ACS T2 Classic...

If you like listening then you'll love feeling it. Words cannot describe the feeling you get when you hear clarity that cannot be described. I was very sceptical spending such an amount on headphone but boys will be boys and I so I brought the best gadget I own. Feeling like you're onstage with Queen or in the same room as Bill Withers while recording is amazing. Every note, every sound can be pinpointed in the room. No matter what's thrown at the T series you'll feel shivers as you wake to how good music can feel, no matter your taste, be that Prodigy or Pendulum to Duran Duran or Bob Dylan, Take it from me if you will - You'll never regret your first pair of T's.

Comments from Ola Onabule, the Soul and Jazz singer songwriter who uses the ACS T2 Classic...

I tell myself “I've been around, I know a thing or two about my game” , the singing game that is. I tell myself I can distill this thing or two that I know into a few handy aphorisms. Some of the better known ones in said game include the evergreen: “You can't polish a you-know-what, but you can stick a flag in it, hype it up and sell it to a lot of people (…as art?)”. Another favourite goes like this: “Don't expect to hear yourself as you'd like to ...or as you think you sound in your head, through the monitors at a live performance. Somethings belong in the controlled environment of the studio, not on a raucous stage at a jazz-funky gig!”. Fair do's, I guess. I've repeated this particular little maxim to myself countless times. Often at the point where I've felt the last spark of positivity fizzle out in my soul at the prospect of an entire gig with scant vocal intelligibility, presaged by a deeply unsatisfactory sound-check, where my voice is little more than a pathetic mid frequency interference amongst competing sounds, squashed behind an immutable feedback curtain. However, I think ACS killed this last adage. I'll explain. 

ACS (Advanced Communication Solutions) make bespoke Silicone moulded, multi driver In-Ear monitors of exceedingly high quality. I got a pair of their 'T' series and and toddled off to Germany to perform with the Grammy Award winning WDR Big Band. A musical experience every singer both intensely relishes and is slightly apprehensive of. This band swings, real hard! With masterful dynamics that cover the gamut of whisper quiet delicacy to thunderously loud blasts! For mere vocal chords and ears, keeping up with all that power, requires superior monitoring. Such monitoring should present a wide frequency range to the performer. A range wide enough to recreate the ensemble, the ambience of the room and the audience response with stunning realism and yet place him/her solidly at the center of their sound field with a clarity that competes effortlessly with that 'In-the-recordingstudio' quality. The ACS T2 Classic's did all this and more ...and at a very comfortable volume, with bags of headroom to spare on my receiver pack. The unstrained aural performance was underpinned by the sheer comfort of the bespoke moulded silicone ear pieces which warm up to body temperature in no time such that I quickly forgot I was wearing them. 

Finally, as a singer I have few/no pieces of kit to pack up at the end of any gig but all of a sudden felt on the same footing as the Drummer as I 'packed' my 'plugs' into its sturdy yet tidy little Pelican case! This is a phenomenal piece of equipment for the ear-health conscious and discerning professional. Simple as! Life before my 'plugs' is a distant memory' I can get on with the business of doing my business to my own high expectations, without whinging on to stressed-out monitor engineers about not hearing myself... ...and I'm glad that ACS T2 Classic In-Ear Monitors debunked one of my little aphorisms. I think the other one may well stand the test of time though!
