The silicon tips offer much more stability in the ear. So $150 mic +$30 high quality USB a to c cable = $180 for a working USB mic. Fit: I have smaller ears so I always have trouble fitting these type of headphones in my ear. They also play the same role of the next track and the previous track as well. With a corded headset, if you so much as touched the plug, it would stop playing. 1 sound from its 2x10w drivers and a 20w subwoofer with bass port for a total of 40w. Also the wrist rest is something I didnt know I even wanted but its actually really nice and isnt too soft, the top 1/4 inch is nice padding and it is medium hardness underneath, a very nice balance, non intrusive and a good width but not too wide to where its awkward to use. Belin is usually a good brand but these things are straight garbage. Other complaint is that I bought these because they have wide sizes but these are definetly not wide shoes compared to other wide shoes i have purchased in the past including from this brand. All for under $20 - Im thrilled with these and am about to buy another set right now for my girlfriend.
