Description
This AK70 MKII comes with an official red AK case and 256GB SD card. It is in good condition with a screensaver on. It works very well and holds excellent battery charge. Issues: It has a small scratch on the right hand side of the unit, on the aluminium, shown in the second picture. I have been unable to get the 2.5mm balanced headphone socket to output correctly. I believe this is an issue with the connector I have not being 4 pole, which is required, but I have no other to test it with. The 3.5mm, USB and Bluetooth outputs all work perfectly. So the unit can be used with headphones with these connections. If you have a 4 pole 2.5mm connector, this may well work, but I can not guarantee this. The case is slightly worn on the edges. Specifications below. Any questions please ask.
