Sound quality is better than the originals for as little 'On Ear headphones are convincing and by far.
For those who like to carry the cable under the clothes: The cable is relatively long, so you can take the phone out of your pocket and use, without having to open the jacket.
A small drawback for those who live a long headphone cord like behind the head: The cable from the microphone to the headphones is not long enough for me. For Normal type of head but more than adequate.
This headset has only one button (the S4 supports 3), it is also recognized the right place and functioning properly.
From me so strong buy recommendation for the original BlackBerry Stereo Headset - HDW-14322-001 5
