I bought these a few months ago as I needed earbuds that would withstand rigorous exercise, and these definitely fit the bill! They fit my ears better than several other wire-free earbuds I had bought in the past and the music quality is good. I can also use them to make phone calls without any issues. The only con is that the plastic charging case is a bit flimsy. I prefer to store these in their case and initially would carry it in my jacket pocket to the gym, but the case slipped out and fell on the ground a few times and broke apart. I was able to put it together, but now have issues charging it. I would really prefer a zippered case as it would prevent this issue.
