I always use a headset with my phone, and I bought these as I was really getting sick and tired of being tethered to my phone by a cable. Plus I have a regular Skull Candy headset that is really good. So glad I did buy them! The offset earpieces fit my ears perfectly and don't cause any pain or problems with sound. I have not been gentle with them.. shoving them into my purse, dropping them on the floor of the car, etc. They just keep working. Best of all, I have been very impressed with the sound quality. Great stereo separation and clear highs, midrange and bass sound. I use them with my I Phone 7s, my Android Galaxy Tab 10 tablet and with my MacBookPro.
I find the charge on these lasts longer than the 6 hours specified, because I tend to keep them turned on and around my neck for almost all day, particularly if I am on a long drive. They also charge by mini-usb cable very quickly, so they are ready to use again in no time.
I do use the detachable collar, as it is comfortable and half the time I forget it is there!
I recommend these highly, and I'm sorry other reviewers had a bad experience with them.
