Hi guys Spent the last while reading up on here, and on the av forums, trying to work out what IEM's to upgrade to. Been rocking Sennheiser CX400s for the last 2 years or so - Bought for £50, loved them, felt like a real upgrade from the PX100's I owned previously. Previous headphones: CX400 <- PX100 <- CX300 <- MX500 <- crappy bundled headphones Current Equipment: HTC Desire Z, Cowon iAudio S9 (gathering dust at the moment but some new headphones might re-ignite my love for it!) Budget £100 ABSOLUTE MAX - ideally less. So, the situation is: My poor old Sennheiser CX400s have been through the washing machine 3x now, and are starting to come apart... I appreciate that they're not particularly audiophile-esque but they've served me well. As you can see from the list above I pretty much have only owned Sennheisers. The kind of music I listen to: These are an example of some of the albums on my phone, a typical example of music I listen to: Justice - Cross Nitin Sawhney - All Mixed Up Braintax - Biro Funk Biffy Clyro - Blackened Sky Elbow - Build a Rocket Boys Plan B - Defamation of Strickland Banks/Who needs actions when you have words Nine Inch Nails - Downward Spiral/With Teeth Chase and Status - No More Idols/More than A Lot Cinematic Orchestra - Ma Fleur At the Drive In - Relationship of Command Atmosphere - God Loves Ugly A Perfect Circle - Mer De Noms Yo-Yo-Ma - Bach Cello Suites As you can see, fairly eclectic. I would describe myself as a "bass-appreciator" rather than a bass-head! But bass is important to me... So far I've been looking around and have thought about... "portable headphones" - decided against due to size/looking a bit silly! - also I like to run/weightlift, and IEMs have always served me better in this. Etymotic xx - no bass/aneimic bass/accurate bass - none of these terms appeal. Klipsch S4 - sounds quite exciting, but not much of an upgrade from CX400s? - put off by the idea of sibilance Westone 1 - Top end of price range but apparently worth a look Shure SE215 - from the first impressions thread these sound like they might be perfect, but priced prohibitively at £99!!! (especially when you can pick them up for $80 stateside ) So guys, for someone who really *does* appreciate hiphop, but also has an ear for a lot of other music, please recommend me a decent upgrade for the poor old abused CX400s I've been lugging around.
