FiiO BTR3K Balanced HiFi Bluetooth Amp - Used (Very Good Condition). I bought this item like new from a third party seller back in February 2021. Ive barely used it since and am now looking to sell. This item is in very good condition - all of the original manuals and dongles it came with are present, the only thing missing is the original packaging. The item is lightly used and only has some minor chipping on the back - besides that, there are no known issues. Works great in order to enhance bluetooth quality and to ease management of bluetooth devices.
