Where do you live and in what country do you plan to buy?
United Kingdom
What is your budget?
My budget is £100 to £150
Are you OK with open cans like the ones you mentioned (they leak sound)?
Interpreting this as would I prefer open or closed. Ideally closed, but I can be persuaded if it would benefit the intended use more. On-ear or full sized would be fine.
What equipment will be powering these cans? Will you be using an amp?
The output from my Xonar D2, the headphone output on my Genz Benz Shuttle 9 (Class D Bass Guitar Amp), *possibly* a Samsung P3 (MP3 Player).
What is the format of your music and other sounds you will putting into these cans?
Format will vary, 192 VBR to 320 Kbps MP3, FLAC. However I have a down-tuned 5-string Bass guitar that I want to monitor.
Describe the sound signature that you are seeking?
Balanced, with leaning towards a punchy well defined bass output, I plan on using Dolby Headphone with gaming.
If you don't know your preferred sound signature (and even if you do), what genres of music do you plan to run through these cans?
Mostly metal, but will be used for gaming and monitoring my bass guitar playing, (Could be a bit too varied in scope I know).
Do you plan to use them outside your home? If so, in what way & with what equipment?
Unlikely, nice to be able to, would be used on a Samsung P3 (MP3 Player).
