a couple of short single presses to the multifunction button on the right ear bud to increase volume and all set. Also, I like that this is a double-tap to end calls; many are single tap, and I would constantly be accidentally ending calls. Its a great home studio mic. Its not the best but neither it is the worst. These slippers are a bit more expensive, but worth the cost. Están un poco grandes, pero A mi hija le gustaron y pronto le quedaran. I highly highly recommend them. The other odd thing is you have to get into the sandals by undoing the Velcro strap that goes across the ankle area. I have always loved Reef for comfort and last summer bought some Reef slides that STILL hurt my feet and arches after plenty of breaking in. I am exceedingly happy with these towel warmers in my renovated bathrooms and the consistently excellent customer service the whole way.
