I use it in almost any situation. Whether, bike, walk while running go or even at home. These cordless headphones are really fantastic. Freedom of movement is optimal and the headphones are comfortable and do not bother if I do wear glasses.
That you can fold the headphones together I find awesome. The headset complies with the expectations well and I saw him often in use. The sound quality is for my ears top, pairing worked without any problems, I could find no disconnections. The volume also for bicycle rides sufficient.
Even as a speakerphone can use the headset. About the middle button on the right earpiece to make calls accept, reject, voice dial the phone, start redials or to transfer an ongoing call from the headset to the smartphone. The voice quality for both conversation participants completely OK. Both can well understand each other.
About the included mini-USB cable of the headphones can be charged. This lasted for about 3 hours. One battery charge is sufficient loose 5 hours.
Conclusion: Successful headphones not only priced but high especially has convinced.
