Pros: Got these headphones on sale for 20 bucks. Great quality and awesome sound. I have had several interchangeable ear buds, and usually they start to hurt after 1 hour of wear. The Pioneers stock interchangeable fits my ears perfectly and I can use them hours ends without any pain.
Cons: Could be better if they had a volume switch attached to the cord. I ride a gsxr and its an annoyance to get out my ipod and adjust he volume.
Pros: The sound from these is better than I hoped for...it is exceptional. Especially for all of us bass fans. I have used them in several devices and the sound is perfect for any genre of music. I am a long time audiophile and these fit perfectly in every way.
Pros: These buds have very clean mids and highs. They are comfortable after getting the right size tips installed.
Cons: The bass was surprisingly weak. I expected these to be bass-heavy, but they have very little lows at all. I tried them with my iPod, also with Marantz and Pioneer receivers, and the bass is just not there. Even at $20, I find these to be disappointing, and I'm surprised that Pioneer has their name on them.
