Let’s get this out of the way early, these discounted noise-canceling heapdhones won’t sound as great or block noise as well as a high end pair of Sony or Bose. But at $120, these Plantronics BackBeat PRO 2's are a fraction of the cost and will improve your commute by a significant margin.
If you’re still using those basic ass Apple headphones, these will be a significant upgrade. You can listen to up to 24 hours of music before you’ll need to recharge or switch to a wired connection.
Better still, these are the cheapest these particular cans have ever been.
