ACS T1 Custom In Ear Monitor
Active Drivers: 3
Build Material: 40 Shore Silicone with SteriTouch
Mould Type: Full Concha
Cable Type: Kevlar reinforced with anti-friction sheath
Standard Cable: Black only
Cable Length: 1.4 Meters
Standard Colour: Clear
Connector: 3.5mm gold plated moulded
Cable Exit: Top (over the ear) only
FR: 16Hz ~ 20KHz
Noise Isolation: 26dB
Impedance: 17 Ohms
Cost: £629
Turnaround: c. 3-4 Weeks
Items Included: Carry pouch, personalised rugged case, wax pick, care and usage instructions, comfort cream, step-up jack connector adaptor, replacement green filters and extraction tool.
IEM's need to be handled with care as they are malleable and it looks as if to much pressure applied in the wrong place would damage internals (though it would have to be considerable!). The cable is very light, connection is very secure, no chance of bent or snapped pins unless you virtually destroy the monitor, (I would hesitate before swapping the cable myself!).
Very durable but difficult to insert without practice, I recommend a mirror for the first few times.
Crossover in detail.
Replaceable wax filters, I was worried that these may have been acoustic dampeners but they are not as you can see.
The attenuation of outside noise is not as good as the ER4's, I was a little disappointed by this but it only really illustrates how good the Ety's are in the first place.
I wonder if the absorption coefficient of the pipe material effects resonance in an appreciable way and if the fact that the armatures secured firmly in the silicon and not supported in an open chamber, as with many hard bodied IEM's, effects the RT? length of tubing and diameter does; also how much trouble do ACS go too in driver matching? With Etymotic this is a principal characteristic of their ER4S, consistency between two drivers, is the same attention to detail paid with multi armature IEM's containing 3,4 or even 6 drivers?

They do not appear to be affected significantly by burn in but that is my subjective appraisal at about 15 hours of listening.
