Negative Positive
Title: Good sound...if it stays in your ears.
Review: I actually wanted the MX75 but the store didn't have them. Thought that the MX70 should be ok. That was a big mistake. Like the previous reviewer I couldn't get it to fit in the ear properly. It was constantly shifting when I was using the treadmill or weights. The issue was that the ear buds were just too big and couldn't provide a proper fit. The irony is that the original ipod headphones (the new ones for IPOD Nano) works much better! It just stays fixed even on the treadmill or outdoor runs.
Is the review positive or negative?
