Very sturdy and easy to install. I get asked about them all the time. Couldnt seem to get the combo I was looking for until I found this. Worked great for a few weeks, but less than a month in, the right ear bud stopped holding charge. I ordered the black t-strap and they also fit well! I have done the infamous Big Shoulders 5k open water swim and the monster swims (100x 100s on set interval) with this unit and never had an issue following the tips I shared above. All very good! So I got these and was super surprised, even if I paid full price it?s super worth it , the bass is better then apple ones (but not overpowering like beats) and sound quality over all is fantastic for the price. Sturdy and good looking. incall sound is good as well but the people youre phining claim you sound like youre on a conference call and are always asking you to repeat everything.
