I've been a long-time Etymotic IEM user. Have had the ER-4P's and the hf3's and like both. Still do. They are high quality headphones to be sure. Partly out of boredom to try something new and partly to get a nice pair of over-ear headphones I picked up a set of Sennheiser Momentum's. I liked them a lot at first. After about a month I absolutely love them. Maybe the cans have broken-in more or maybe I've just gotten used to them or maybe both but all I can say is that they sound incredible to me now. Also super comfortable too.
This brings me to the predicament that when I put on the Ety's they just sound a little flat, a little lacking in life, a little lacking in soundstage (not wide or deep) and separation, too much high emphasis, too little bass (both volume and impact wise, most notable on drums) and not as comfortable as I remember now that I got used to the over-ears. Don't get me wrong the Ety's are still great it's just that I have now realized that I prefer the richer, warmer and fuller sound of the Momentum's. I also understand the Momentum's are very highly thought of in the first place with rich deep bass and a balanced and warm (and darker) sound with slightly rolled off highs, are obviously over-ears with 40mm drivers and cost a good deal more so not a fair comparison of course.
As a result I am looking to replace the hf3's (no longer have the ER-4P's anyways) with another set of IEM's that will provide a sound signature that is closer to the Momentum's. I'm also trying to keep it under $250 as I will mostly use the Momentum's but will likely use the IEM's on vacation, etc. Looking around the headphone.com charts I see that the Shure SE315's have a somewhat similar frequency response curve.
Any advice on how I can as closely emulate the Momentum sound in IEM's would be appreciated. Another option seems to be the GR07's (likely bass edition?) though I've never tried or seen those anywhere. Can't seem to find their frequency response either. Any thoughts?
Update: In the end I do understand that I just may not be able to get a sound that is similar and as good as the Momentum's for that price range in IEM's in which case I could keep the hf3's but if I can I will be tempted to swap out the hf3's if I can sell them at a good price.
