I have had my Etymotics ER-4S for almost 10 years. I started out using them with and Airhead and a CD Player and then of course iPod, now iPhone but stopped carrying the amp when the iPod came out. I am very frequent business traveler so that is where my cans see all the action.
I stopped off at one of those Inmotion stores in the airport and started trying out new ear buds looking for something with better low end extension than my Ety's. After listening to several I liked the Monster Coppers the best. Came home found a pair bought them...for hundreds less than Inmotion.
So I just got home from a trip and this is where I am at.
I love the fit of the Ety's miles better than the Monster. I can get them in and out of my ears quickly. I also love the well documented high end of the Ety's but think they lack bass in compared to the Monster Copper's. However I think the bass on the Copper's can get overwhelming bordering on annoying. The Coppers are way more efficient and can be easily driven to the point of "way too loud' even by my 32gb iPhone 3GS and I like that as I don't intend to carry a portable amp.
I guess I am looking for some suggestions on what to get. I'd like to morph the high/mid attributes of the Ety's with a toned down low end I get from the Coppers plus the comfort of the Ety's. I don't find the Copper's easy to get in and out of my ears. I think that is mostly to do with the narrow design of the Ety's. The Klipsch go in and out really easy and as you probably know they are physically the most similar to the Ety's. Another very superficial thing I do not like about the Copper's is the copper finish. Looks like ear jewelry.
I closing I tried the Etymotic HF5 and liked them and I did not buy them because I will never use the mic part of it. I'd also like to try the Ety ER-4P which is what I am leaning toward I read somewhere that the HF5 and the ER4-P are sonically very similar if not exactly the same, any comments??? Any non-Ety product that I should be checking out?
