The Etys' microphonics is a non-issue to me. I drape mine over the ears and down my back. I operate machinery at work that requires me to move around quite a bit, and I have zero problems. I appreciate the hearing protection they offer me. The only time they are a problem is when some idiot...

I think it depends on your ears (as in how much wax they produce and how clean you keep them). I have had my ER-4Ps for a month now and the filters are still clean.

The SlimX does not have that flaw. There is no hissing on mine. Iriver posted that the problem with the IMP/SP-250 was due to having more than one supplier of the amp, but the IMP-350 does not have that problem. I am still very impressed with it, and that is after nearly 3 weeks of heavy usage...

MusicJunkie, I swear by my SlimX CD/MP3/WMA player. I use it with my ER-4P and it is divine bliss.

I find bringing the cable up my back to work really well. Looping around the ears helps with the weight and block microphonics from the cord. I do have one issue though. When I walk fast, I hear the breeze in my ears. It is a "whooshing" sound that picks up as I take a step, then dies down...

How are the ER-6s with regards to microphonics and how well do they stay in your ears? I am looking to replace my Sony MDR-A30Gs with something at least as comfortable, offers sound isolation, and much better sound experience. I am very tempted by the ER-4P, but I do not want to pay that much...
