Summary: A family member received these as a Christmas gift last year. He was so impressed with them. I had to try them for myself. I have to say that it's good quality compared to the pricier counterparts.
Excerpt: My fiancee and I were using Apple earbuds on our iPhones, and I was looking for something louder that would cut background noise. WE LOVE THESE! The price is right, they're loud, they cut background noise a lot, and they even feel good in our ears. We use them for cell calls, cutting background noise at work, and for books on tape while driving.
Pros: Cut Outside Noise, Louder Than Apple, Nice and loud
Cons: Volume Buttons Stiff, Wire Is A Little Stiff
Summary: Had these for a few months now and I'm impressed. Before these I had a set of V-moda Vibe Duo, which is considerably more expensive. This Panasonic set fits better and doesn't fall out as much, and is more comfortable for prolonged use. The sound quality isn't perfect, but it's not as bad as some people here seem to be making out. The only time I've had a problem is with heavy metal. Anything else they will play well.
Summary: I love these headphones. My first pair lasted over 3 years which considering I use them daily whilst commuting is great value for money. I have previously had issues with canal in-ear headphones as after a while my ear tragus (the flap bit) hurts from them being pushed out by the headphones, not with these ones. Because of the design of the ear piece they fit perfectly and I can wear them for hours with no issues.
