So how to they compare to the competition? An obvious rival would be Shure's flagship SE535, which carries a £478.98 RRP, but can be found online for nearer to £400. The SE535 has been our earphone of choice, but there is a significantly wider soundscape to the T2s: a sense of cinema verses IMAX. The T2s also offer greater clarity and are more immersive. The fact the SE535s don't come with custom moulds may make the comparison unfair, but Shure doesn't offer them. You could get third parties ones but they lack the full ear mould of the T2s and their swanky flush finish, and they'll still then set you back circa £500.
There are a number of other custom IEM manufacturers but several don't operate in the UK and most only offer hard plastic moulds so again miss out on the comfort benefits of the T2s. What's more, the silicone offers better sound isolation, further reducing the need to crank up your music and potentially damage your hearing - one of the key benefits of custom moulds in the first place.
Even in noisy environments like the London Underground the T2s create a serene, calming silence for your ears to enjoy.
What price do you put on the best? The ACS T2 monitors may cost £500, but they represent a new high in earphone sound quality and audiophiles will be bowled over. The custom moulds fill the ear canal to create the perfect soundstage and the flush design is practical when you want to put your head down. Finally the bespoke seal means you will have never enjoyed listening to music at such low volumes. Your bank manager may not thank you, but your doctor, your heart and your soul most definitely will.
Note: Now is probably not the best time to tell you ACS makes a flagship triple driver £650 T1. We'll have a review of this truly frightening creation soon.
