Summary: I have other JVC Marshmallow headphones (another older model) that stay in place better and block more external noise. But these still stay in much better than regular earbuds, the sound is good, the mic is good, and the color matches my Shuffle and phone case. I wouldn't pay full price of $20 for them, but I'm cheap!
Summary: Works with T-Mobile MyTouch also. I was worried after getting it in the mail since the package shows only ipod & blackberry as compatible. However, the ear buds work great on my phone and have great sound.
