The sound quality is comparable to other basic headphones, and is good for music, audiobooks, and even phone calls. Initial evaluation :Best one Ive had. However?if you like very fluffy pillows, this one is definitely worth a try for the price. Very easy to use on a laptop. ???? (40 inches). sorry. Ive worn them three times now--theyre comfortable and they stay put. What a scam! Meaning, button or no button, on ANY headphones with a mic, or having your phone nearby (which obviously has a mic), the assistants work.
