Great Sound but I should have bought the FLEX version for multi connections
6 September 2014
Summary: Note that there is a difference between the S11-HD and the S11-Flex HD. The Flex can be connected to two Bluetooth devices at one time - according to the instruction book for the difference versions. This model does not. SEVERAL basic areas. SOUND: Great Sound. Crank up the MP3 and the sound on this device and it is very clear.
Summary: after owning several pairs od the s10 headphones , (which all by the way we excellent for everything but a heavy workout)I decided to mve to the next model the s11 flex. the feel was very similar, and the power button was no longer on the back center ( where all of m s10's had failed from on/off failure) the welcomed better bass sound and equalizer with 5 presets all wrapped in a multifunction bow was very very cool.However that is where the awesome factor ends.
Summary: I bought this hoping for a great product. That's just what I got! I was tired of my earbuds getting torn out of my ears at the gym when the cords caught on various objects. I figured these were worth a shot and I'm very happy with them. I can even lay on a flat bench and the wrap around band does not even get in the way!
Summary: So far so good. Only complaint I can find about the headphones is on occasion the headphones have a 2-5 second delay when powering on the device. They are comfortable and loud enough for my workout.
