Could someone explain to me Ohm's had a quick look at wikipedia and just went oevr me head. At work currently and had a customer moaning about some headphones and Ohms on one set being better than the other and didnt really know what to say tbh. Was going on frequency range on one pair being better. Cheers guys!

You work in PCWorld you arn't expected to know anything about computers, just how to ripp some old people off into buying something by bullshitting and using technical terms haha

Ohms are not power rating.

Ohms are the unit used to measure resistance of an electrical component/circuit etc....

In relation to what your asking about sound then resistance plays a part. The higher the resistance of the speaker then the harder the source amplifier (be that an internal amp of an ipod or external in a house/car) has to work to provide it with power. This increase resistance effectively limits the power it can be given which in customer terms means loudness.

If the resistance is lower then the amp can supply more power to the speaker due to the lower resistance of the speaker. The knock on effect is the amp gets hotter and requires more power to run it.

So a 32Ohm earphone would be better than a 60Ohm speaker for example. Cheers Scott!

Daryl, unfortunatly im too honest to rip people off, i have a conscous(sp) I like to advice what i think is best and let them choose. Although many customers moan as i dont force them, and dont like it when i have to ask someone else for help. But i cant know every specification and what everything does for every product we have!

it would be louder yeah, but not necessarily 'better' dude.

sound quality is more do with the materials chosen and design of the speaker assembly.
