Sadly these are not functional enough to keep. This last pair I bought has remained water proof for 6 months. Solo falta ponerlo en las bases del coche. I used it on a custom 450 size drone and just used the servo lead to open and close the pin setup, works great. Perfect size for the side of my sink, which was very difficult to find in the quality and finish I wanted. Pros:- Good noise cancellation- Audio quality is very good- Battery lasts a while (though it would be nice for a little bit more time, since some flights can be 15+hrs)- Earbuds fit well, the attachments are quite nice- The carrying case is very useful- Their customer service/warranty people are amazing and the process is seamlessCons:- Construction could possibly use some improvement (my first pair died due to an internal component becoming dislodged, after 20~ uses); NOTE that Bose fixed this very 2nd picture - For comparison I put them against my birkenstocks in the same size (size 8/ 39). What?s a little bizarre, is that I?m not sure why this matters?they seem to be identical on each side. 2) the rubber straps that secure the bike frame into the grooves mentioned above are a little difficult to get on tight and then get back off due to the position of the notch being so close to the arm of the rack. ( will not test it :) ) Overall I?m happy with it.
