Thank you for viewing. Please take a look at my profile first. KZ Symphony KZ Symphony I purchased this last month on Amazon. It has a wide soundstage like the PR3, with a combination of the mid-high and high frequencies, and the low frequencies of a dynamic driver. I am selling it because I purchased another pair of earphones. I have used it for about 3 hours. The ear tips and cable are unused. I purchased the cable with a microphone, so you can make calls and record audio. Both the box and the main unit are in good condition! Please understand that this is a used item, so please purchase only if you are okay with that.
