"Best in class in audio, design, and durability."4.0 starson by konradjohn
Pros: I have had a pair of Sennheiser PMX 70 Sport headphones for two years now and I have had no problems with them what so ever. They hold firm to my ears, are lightweight, sound great, and come in vibrant green and orange colors.
Cons: I believe they could be a bit more comfortable with some gel like ear inserts that are softer on the ear. Also they might take some adjustment to find that "sweet spot" in your ear.
Summary: After testing many different styles of headphones and earbuds I have settled on the Sennheiser PMX 70 Sport headphones. I can affirm that they won't fall out of your ears like earbuds and at the same time don't have to cover your whole ear. They are light and tend not to hurt your eardrum if properly positioned right. They sound great with a surprisingly deep bass. Overall I believe Sennheiser has found the middle ground between over the ear headphones and earbuds. I will definitely recommend this set of headphones to my family and friends.
