Can use Alexa on normal mode but I also have it on my phone and other devices! Have tried +5 sleep headphones and these are by far the best. Best flip flop ever dressy girly casual comfortable I have the adult version and I got my daughter these and she loves them as well just a great quick slip on that goes with everything three seasons out of the year its worn Particularly the ones that have a slightly larger (flared out) bottom than the body of the spice jar. I labored over buying them because there is sort of a stigma the goes along with Croc wearers. You wont believe your ears. I like this lightweight headset. Was not expecting this for the cheap price. Easy to put on and off Très belle sandale et me vont très bien.
