I bought this pair of headset from Amazon earlier this year. The sound quality is very impressive just as advertised (energetic sounding). After a few months of use, the headphone began to fall apart. First was the rounded rubber. Then the plastic part broke, which can be quite annoying sometimes. Due to those two failures, I had a hard time keeping them in my ear during running workouts. 
 
Overall, I am satisfied with the headset. I would recommend this pair to my friends.

Decent headphone for begineer. It work well on flights. But heavy and warm. Definitely a heavy-duty headphone.
