Review title: Fantastic Sound (Especially the Bass)
Product review: If you have an iPod and are not happy with the sound of your current headphones, then try these. The one thing no one explains to you, when you buy headphones, is that you need to match the impedance of the headphones you're buying, to the output impedance of the iPod. Most iPods have an output impedance of 32 ohms. And yet the majority of headphones sold have an impedance of 16 ohms. That mismatch affects the sound quality, especially the bass. I have an iPod Nano and I bought these Sennheiser headphones specifically because they have a 32 ohm impedance. I couldn't be more pleased with the incredible bass response. Fantastic sound !!
