This is a revised review. I bought thee in March 2020, and although I wouldn't call them 'audiophile quality', they do the job I intended. At the gym they are light and unobtrusive, and they SEEMED TO stay snug while walking/jogging/etc. Decent sound quality (a tad 'bassy' imho), plenty of quality to listen to streaming news or Spotify while exercising. In March, I used these when walking, working out, or doing yard work. In April I did not use them at all (sick). In May, resumed use. By Mid-July, these phones had begun to lose the 'memory shop' of the band that goes across your head.... so much so that the thing would just fall off my head if I was the slightest bit sweaty due to activity. So I began to store them with a tight rubber band squeezing the ear pads together in the hope that the phones would 'snug back up' on my head. Seems to work, but only for a short time (like less than an hour), then why become very loose again and are almost more trouble than they are worth. Bottom line: Decent sound for the price, but the quality of construction (usability) is. very bad. Unless I am wearing a hat or sweatband, these thing don't stay in place. I CANNOT RECOMMEND THIS PRODUCT.
