I have a question. Since it involves KZ IEM's so much, I'll put it in this thread instead of the Chinese / Asian Brand IEM thread. I have some KZ ES4's that I really like. I like massive bass, minimal treble, and nice durability. I think the ES4 fits the bill well. Also I have ginormous ear holes and the only silicone eartips that fit are these: Are there any IEM's not made by KZ that are similar to the ES4 for about $15 or less? (The above ear tips have to fit the IEM in question.) Oh, yeah, detachable cables are a nice bonus.
