This red and black pair are not the same quality of grippies on the bottom. Im very pleased with this purchase and would both purchase again and recommend to friends/family. This dress was worth the gamble, for sure, but my advice to other buyers would be to order a size that you normally are in tops. - There is a microphone somewhere under the spacebar for one of the lightning setting. They’re good looking and my favorite part about them is that the soles Are thick so I can wear them on the cold floor and my feet don’t get cold. So cute, looks like my Sunny. Yes, the Burson with an excellent amp section and the Shanling with its warmer note give aid, but without the IEM bestowing the note, all would be lost. Lo peor es que no deja cambiarla, por lo que tiene que ser un problema de drivers en Windows. It has the Thunderbolt female on the end that goes into the microphone, and a USB on the other that will go into your laptop or desktop computer. It just gives you the material.
