The 558s are way less portable, I'm pretty sure they don't come with a 3.5mm jack as standard. Weird pair of headphones to be deciding between though...... aren't the 205s pretty cheap in comparison? I'm personally a big Sennheiser fan but if you considering spending toward $200 on those 558s there are some very good alternatives to consider. Namely the Audio Technica ATH-M50 headphones.
