Pros: -Comfortable -good battery life -good audio quality Cons: -The first pair i brought were fine for 4 hours then the left earphone refused to charge. -The second pair I received, after a couple weeks of use (5 hours a day, low volume), the right earphone is getting quieter and quieter each day. Conclusion: I would not buy these again, nor would i recommend anyone else getting them. Especially for $200.
