Using the S-11 Flex has advantages when doing vigorous workouts. The buds stay in the ear due to the pressure from the headset frame. Theres no need to continually adjust the buds due to rapid head movements or excessive perspiration. Bluetooth connection works well, but if you have devices competing for the same Bluetooth connection, youll have some difficulty with getting the signal to stick with your device of choice. I found it better to have other devices forget the S-11 signal so that theres simplicity in receiving the device connection.

The EQ choices are helpful, and the sound of music coming into the ears is average. Nothing terrific is happening with the music quality in any of the settings. My point of reference is the Apple EarPod, which, from my POV, offers surprisingly superior sound from what appears to be three drivers in each EarPod. Id rather write about Apples pods due to the great sound quality, but the Flex S-11 nonetheless does what its supposed to do: stay in the ear, offer adequate sound, and establish a good Bluetooth connection between earpieces and the sound source.

Pros: excellent sound quality
Cons: poor build
Althoug I was amazed by the sound , the quick charging time , long range and battery life. I was quickly disappointed as the neckband broke literally for no reason in one week of very careful use then a month later one of the earpieces also broke and a few weeks later the entire unit is barely holding itself together by the internal wires. Such a pitty because the electronics are top rate but the structural integrity is way below the reputation of a well known manufacturer
