These headphones are made very well, are good size, and are comfortable to wear. All the functions work well, but on occasion, the Bluetooth connection appears to be weak, or the microphone volume may be weak (people have a hard time hearing you). Sound quality is excellent. The radio function is a plus as well, but I have only used it a couple of times.
The cons are: the placement of the multi function button, and the battery life. It takes about 30 minutes to fully charge the headphones, but the length of time to listen wirelessly is about 2.5 hours, which is considerably less time than other headsets in the same category.
I found that the micro SD card is great for listening to audio books.
I also like the fact that there is an actual on/off switch.
These headphones also take a little longer to connect to Bluetooth than others.
