And I am a professional sprint racer and athlete I always need a earphone type music listening device to stay be more motivated for proper training.
But when I am sprinting on the road the wires of the earphone get tangled with my forearm and remove the ear phone from my ear.
Then suddenly I saw the advertisement of Sennheiser Bluetooth headphone in to Mall and I take a free trial of it and you know what I found it pretty useful for me because it is connected to Bluetooth device of the phone and there are no wires to be Tangled.
Range of the Bluetooth is also for enough to continue my practice session the sound of the headphone are also very good because they provide 20 decibal of sound
The one thing I didnt like is the style and design of the headphone they could have made it better.
If you really want to eliminate Tangled wire from your earphone it would be useful
