The product arrived on time (less than 30 days, which is fast for my country), well packaged, and with all the contents inside the box. The earphone is really bluetooth, the finish is good. I used two weeks to run and the battery has a good life. The sound quality is good, it's not super, but it's good, and it reaches a very high volume, enough to suppress any sound in a gym with ease. I leave a photo for you to see what comes in the package. It has different plugs for each ear size.
