Summary: I own many Bose products and love them. These head phones are junk. They only sound average, they are not loud, I can not hear anything with the sound half way up & and at full blast I can not even hear the music on the subway. Using these with iPhone 3G. They do NOT stay in my ears! I had a pair of V-Moda Vibe Duos, that really put out!
Cons: Can Not stay in ears, Low Volume, Not loud, Sound quality Average
Summary: These headphones sound great - much better than the stock buds that come with an iPod. The problem is the removable silicon pads that let you adjust the phones based on your ear size - these things fall off VERY easily. This is incredibly annoying and make this product a bust. I expected much better from Bose.
