There are 3 versions, one with only a 3.5mm jack (which is what I ordered), one also with a USB charging port and one with a lightning port. The product (and Revain) says not to charge and play music at the same time (so probably some people had sound issues). But if you install and use it properly, it should work just fine. Two other things to note: 1) If you have a case on your phone or device, you should probably get a slim adapter so you don't have to take the case off. . The 3.5mm jack on this product is not thin and will not fit in most cases. I ordered this adapter (https://www.amazon.com/gp/product/B074S15X7W/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1) and the sound is still great.
