I recently got the ACS T1 IEM. Although all the pictures I found of it have acoustic dampers in the tubes, mine don't. Does anyone else with recent models also have the dampers missing? I know this affects the shaping of the sound on the high end.

Has anyone had experience with both ACS and Sensaphonics custom IEMs? I think I want to go the silicone route, but am unsure which may be better for music listening. Any input would be great. Thanks!

Intro Here is a guide on how to slightly modify your ER4 custom IEM tips to make them sound much better.   Background Some others on Head-Fi had mentioned decreases accuracy and shrill sound after installing the custom tips on their etymotics. I recently bought a pair and also noticed a...

I recently acquired some laboratory tubing that is the exact same dimensions as the tubing in the stock foamies for the Ety er4. Therefore you can make your own foamies. With the polyurethane earplugs and a 2.5mm leather punch, you can use this tube without glue, so the tubing is reusable. If...

Ive had my ER4p for many years. Im looking to improve it somehow. What would be the best thing to do / get? I currently have a zero audiocraft amp. I use the triflange eartips.

I have an Idea. What if we came up with a standardized test CD (or flac, ape, whatever) to put headphones through their paces. I have the means to put something like that together, but I'll need ideas on what to include. We should be able to use snippets of music tracks under fair use. In...

I don't know if I should put this in the group buy section or not, because i'm just gauging interest. So if it belongs there, please move it. Idea is to see if we can get a group discount on the little green filters for the etymotic ER4. Don't know if we can, but its worth a try.

What would be a good amp for the ER4s, I have a zeroaudiocraft (dual cmoy). Is that sufficient or are there better options? Thanks

For the ER4 foamies, which side goes in the ear, the glossy side or the other side?

Is a custom ear mold for the ER4 worth it? Where is the best place to get one?

Here is an interesting audio sample I've made. Give it a listen all the way through - it works with some headphones better than others. ER4Ps are freaky, as id imagine any IEM is. I wont spoil it, you'll just have to listen. I've found some other interesting effects. If there is some interest I...

I have had my ER4Ps for a few years now, I use them every day. They go where I go. Last year I had to have the cords replaced because the connector on the left earpiece kept falling out. The old cord was rubbery and looked well made, the new cord is plasticy and shiny. It looks like a piece of...
