A week or two ago my dad said he wanted a pair of ipod style earbuds for biking and kayaking, so I ordered a set of Sennheiser MX75 Sports. Maybe not the best ones, but they would stay in fairly well and are supposedly water resistant. I got them today and noticed they had 64 ohms of impedance. I have a set of HD555s and they have 50 ohms of impedance and don't sound all that great unless hooked up to an amp. SInce the MX75s are small earbuds designed to be hooked up to a portable device, they should still be fine coming straight out of an Ipod right?
