The wireless function works great, and the battery lasts much longer than expected. The lip on the pods are so small when you would try and attempt to stretch it out to put it on the pods. I was going to return them and decided to wear them to work and try them out, I am SO glad that I did. I definitely recommend these slippers. Had to glue covering back on. I only wish they were a solid color but as long as shes happy, Im good. If they were of better quality I would give this product a better rating. En general es complicado describirlos porque no son las perlas de la virgen, pero todo lo que prometen lo hacen de bien/muy bien a excelente. Sound quality so-so, noise canceling non existant. Absolute Kaufempfehlung!
