I'm honestly blown away by the value of these cheap earphones. I didn't want to spend a fortune on a set of Samsung or other brand name set and I was keen to give these a go. They're so easy to use, simple to work, and easily pairs via Bluetooth to my Samsung S9 – doesn't need any additional apps to work or anything, just straight connection with Bluetooth. I'd say the only issue – and it's something you'd get used to – is that they immediately connect at full volume which is a startle, but again it's something one will get used to. I'm absolutely thrilled and fully recommend to others.
