I have scoured this forum for advice on a good classical music IEM, however the only general consensus is Ety ER4, is the best. But I dont have that much money to swing on a pair of headphones. I have included a list of other headphones people have talking about in the other forums. I am a college student and needless to say, I love listening to classical music. The majority of my iPod is classical music, all CD quality 320 or better. Microphonics is kind of important, I move around a decent amount and I would not like that to interfere with my music. Isolation should be enough to tune out annoying kids in the library. One with a microphone would be awesome but I dont really see IEMs that have. Other headphones that users have said that are good for classical music: Westone UM1 RE0 Ety ER4 Shure SE215 Ety HF5 My main concern with IEM is the price, i wont think I will be willing to pay more than 150. tl;dr hear ER4 is the best for classical music, what is a good substitute if i cant swing 250 for a pair of IEMs? Thank you very much in advance!
