I used for phone calls it was great sound and the volume control worked even I used it with a flip phone (Kyocera s2720) the mic works great the people told me that they really hear me well so its really good buy 2 of these for this price The sound quality is crap unless you get the right seal inside of you ear. they only message only on WhatsApp. Works great in a tight laundry room and easy to install. hope they get this fixed I have thick fingers so sometimes delicate operations are not that easy for me. I normally order shoes in 6 wide; these in size 6 are perfect. She was EXTREMELY satisfied with them. Arrived as pictured, unicorn a little bigger than expected. I was skeptical about this but it works!
