There are a few small issues, but weighed up, they can be overlooked for the price and quality of this product. I wasted a bunch of money on cheaper stuff with no satisfaction, then I discovered the Jabra sets, I bought two of them and the sound is awesome. I will update the results****UPDATE****Went to an indoor range to finally test these and they work great! These stick out quite far. On a weight loss journey and this has been helping me tremendously. So the Bose effectively has a volume adjustment of 0-100 when done manually at the speaker. Yo lo pedí negro pero me lo enviaron azul, la verdad se ve mejor el color azul, pero eso significa perdidas para el vendedor porque tienen diferentes gamas de precio, pero aún así gran servicio! The only this is, is that is burns your eyes if you get this on them. This phone can easily sustain a days usage. If you are looking for the same, you might want to buy these because I did a lot of looking around and a lot of headphones under $20 are really cheap, not quality.
