They fit comfortably in my ear and pairing literally took less than a minute. Only two very simple steps, open the case, headset flashing blue, select the earbud in Bluetooth menu. After the initial connection, the next time you open the case, it will connect your phone automatically. The sound they produce was crisp and clear with nice deep bass. you can hear a nice clear sound even over the noisy square. BTW, you can connect either earbud independently according to your needs, which seems very convenient.
