They are ok they fit great and it's nice to see that they have different sizes for ear cups, however, they are very expensive and don't offer much vocal sound in songs because it is overpowered by the extreme bass. The case is unpractical and big which means you won't be slipping it into your pocket easily when you are on the fly. However the passive noise blocking that comes from the ear cups are actually pretty good I couldn't hear people sitting next to me on the bus talking, so they are good if you want to wear them in public places yet still hear your extremely bassy music with average vocals. They do not do Sennheiser as much justice as I was expecting.
After a few days of use, I can clearly recommend these for everyday use.
Mid-High is really nice with clear audio and crisp treble.
That judgment falls on the base, as bass junkie so I think it made it that little extra lash. They're not quite as far down as I wanted but is clearly still working.
For having the fitness center and commuting to work them really good price for a similar price tag. Turns out all sounds really good!
These are calibrated as happy arc with lot of treble. Probably even more than the CX300. But not so much that they sound weak because the base is at least as deep as the CX300. Still have not got used to them really. To listen for long periods to provide a slutgilltig rating.
