That depends on what I'm listening to - and how I'm listening.
Today at work I was listening to the utterly amazing TRON soundtrack by Daft Punk while churning out Powershell scripts (automating the deployment of SCOM clients for new customer servers in our hosting center, thanks for asking) the music and (c)iem combo served to keep me motivated as well as block out the background noise of the office. Went with the K10 for their combination of soundstage for the orchestral pieces (
Nocturne) and hard-hitting, flawless bass for the EDM bits (
End Of Line,
Derezzed).
After lunch I started work on a new script (automated validation of backup configuration; super exciting, I know). Starting a new script from scratch means pen and paper as I jot down the logical steps needed and starts to work out how to get them done as fast and efficient as possible with code. So instead of coding
like this, I'm working out stuff in my head
like this. This is where I put on something like
Fink Meets The RCO or maybe
Agnes Obel... and the Katana.
I do tend to use my K10 a tiny bit more than the Katana, but that's simply due to its superior comfort (ciem vs universal) for me and my wonky ears.
By sonic merits alone, I could live happily with either one as my only headphone.
Well, until The Wizard finds a way to magic K10 bass into a Katana, that is.
