I spent a couple weeks researching and picked these. At first blush I did not like these headphones. I have not had to wear them out for the day yet but I will update my review once I know the comfort level after a full day if wearing. It supports 3A Power Delivery charging for my nexus 5X. It?s just an all-round perfect book. 3 1/2 years later I have worn these to stores and outside in bitter cold to my car or mailbox and slippers still going strong. make sound. Excellent price and quality. After doing a chat with Amazon they told me I had to handle it with the seller who is supposed to be calling me to provide me with a prepaid label to return it and to discuss a replacement phone. Theyre simply competent with near zero excitement.
