Summary: I've tries earbuds many times over the years and always end up going back to a pair of lightweight Yamaha headphones from the early 80's that we sold to use with electronic keyboards.
Pros: These little earbuds do a great job of noise filtering and provide a nice crisp sound with clear highs and mids. Base is a bit weak, but they are earbuds and you can't really expect big base out of them. Overall very satisfied.
Excerpt: Good sound for something at this pricepoint - my M9-SLs sound about the same, but have a better fit/more selection of tips, and also a soft carry case (which I assumed was just more or less a given at this price point).I think overall good sound, but not a great value.
Summary: I have a problem with headphones staying in my ears. These seem to stay put. They are contoured to fit in your ears comfortably. My 10 year old also likes them so I had to buy another pair so we both would have some.
