Headphone impedence

Im looking to upgrade the phones on my walkman A series which has a volume limiter. The headphones that have a decent volume tend to distort.
Is there an ideal impedence range for mobile devices for a clean sound ? They seem to vay a lot.

Exactly what im looking for thanks. I dont think many manufacturers state SPL but i will look out for it.
It is not just impedance, but also SPL (sound pressure level) that makes a headphone easier to drive by low power amps, such as those in mp3 players. As a rough guide less than 50 ohms and more than 100 db/mW SPL will be fine, but to give you an idea of how this works, you need a 10,000 ohm headphone such as the Sony DR4C before it just will not work.
Internet - laptop - DAC - amp - lots of headphones.
