Pros: Comfortable, Optimal clarity, Great sound quality, Ample storage, Good battery life
Cons: Fogs up, not 100% rain proof

The thump pro are perfect for any cyclist especialy duing training. Sound Quality is excellent and frame is light weight and controls easy to use. Only issue you may have if you want to do training indoors on a trainer is that the heat of your body will fog up the lense. This is where a flip up lense would be suitable for this application. Alternatively if the speaker booms were a littile longer you could put the frame on the top of your head for indoor useage and still have the speakers in your ears to continue listening to tunes.
