There are several warning messages strongly recommending users to read and be aware of before starting to use this device.
Earcup rotation: a) Each earcup is 90orotatable; b) Rotate earcups slowly and carefully; c) Resistance will arise when a rotating move is in a wrong direction or out of 90o capability; d) Immediately stop rotating when resistance arises; e) Ignoring arising resistance and forcely rotating earcup in a wrong direction or beyond 90o capability may result in hinge damage, where two screw holes in the hinge will break under overstress.
Replace earpads: Please be aware of earcup rotation resistance during earpads replacement. When focusing on putting back earpads, there is a chance to ignore the arising resistance signalling earcup ratation in a wrong direction or out of 90o capability. A recommendation is to keep earcup in 45o position during earpads replacement.
Elastic Rubber band: Because elastic rubber band in traveling EVA case is tight, users may have to push headphone earcup to pack or unpack headphone. If the push turns into a force overwhelming rotation resistance, hinge damage may happen. A recommendation is to remove the rubber band by cutting it off at both ends.
If users have any questions about those warning messages, please contact us via support@mo-electronics.com. If users already broke up the hinge, please also contact us to get a replacement.
Was at RMAF17 and met Dr. Wang and heard these headphones. Lightweight and comfortable, yet still maintained a firm fit. Frequency response, from top to bottom, was very even , with no undue emphasis on any range. Smooth and detailed, never fatiguing. Highly recommended!

Mountainman: Oh my word these are really great! Perfect for extracting the maximum sound quality you can get out of your phone. I find it humorous that some people spend hundreds and hundreds of dollars on headphones for their phones... I mean, you are limited by your lowest common denominator. For most people, that is the music streaming through their phones... Ugh! But these headphones do compete well with others that cost three or four times what these cost (probably even more). I don't know how they supply such great sound at this price...
S2kPanda: Sound: 6/5 - The most important part of a headphone review... how does a headphone score an extra point on a 5 point scale? I'll tell you that out of the box these headphones sound spectacular for their price.
PACsman: Best Bluetooth sound quality I have heard! Layered sound! I didn't know Bluetooth could deliver layered sound! Bose, Sennheiser, Sony, B&O, Bowers and Wilkins, and other's don't provide any sound detail. M&O does!
S. Riley: A Great price performance Bluetooth headphone
InvoluntarySoul: Supreme bass, detailed mids and rolled off highs, I find this signature very enjoyable and non fatiguing
Akhilesh Bjaj: Superbly designed device that improves your life significantly. My strongest recommendation.
Silver: The highs are crisp and don't drowned out by the super clear mids.
Regina Hammock: Smooth and detailed, never fatiguing. Highly recommended!
