Its been wet and worn through sports and its still holding up. I used the size chart included in the photographs of the shoes. Those wouldnt stay in my ears at all whenever I tried exercising plus they were pretty uncomfortable. On the other hand if you need a balanced sound where you can hear the details of the music you should choose PLANTRONICS BACKBEAT PRO 2. Loud sound high quality product very durable, I bought these when they first released and after quite some time I thought it would be best to now get another pair in order to replace the ones that I have now since I have now noticed that after these have been first released I have now almost basically destroyed them from all of the exercise running and water that I have been putting them through they are extremely high-quality very durable and lasted me quite a long time which I am very happy to I downloaded the Sony app and can make the adjustments and will be giving my Bose away. I eventually ignored the instructions and just proceeded using what i saw and common sense. When I read the "Toe box too big" comment about the Vangelos, I knew these were for me. When my legs are cold, the pain increases dramatically sometimes to the point of rendering me unable to even bear weight so, it is critical for me to try and keep my legs warm! Purchased the Mi Air purifier after doing some research on which purifier would be best to help alleviate my husbands allergies and so glad I went with the Mi.
