good+ Otium Customer Service is

7 Waterproof Stereo Earphones (Bluetooth 4.1, Secure Fit Lightweight Design, CVC 6.0 Noise Cancelling Mic, Fast Pairing)These great sounding Otium earphones provide crisp, clear sound and dynamic bass for a small fraction of what you would think they cost

I do have to say that for bike riding I perfer the larger Otium Best Wireless Sports Earphones w/Mic IPX7 Waterproof HD Stereo Sweatproof in Ear Earbuds.

My favorite for sound quality and comfort would be my Beyerdynamic cans, but it would not be right to compare those to these entry-level / affordable Otium bluetooth headsets
