Here is KingSound’s flagship headphone, the KS-H04 and the M-03 headphone amp as a combo package. On its own, both the KS-H04 and M-03 are one of the best buys out there. Great musical pieces in their own rights. We had sold their former flagship before, the KS-H1 and can confidently say, the KS-H04 is a much improved version. It has a lower bass extension (6Hz) than the former flagship (10Hz) but both flagship models sounded incredibly smooth (the KS-H04 hasn’t even been burnt in yet). The M-03 is a rechargeable headphone amp and just require a micro USB cable (the type that is used to charge Samsung/ LG etc phones) to charge it. Once it is fully charge, you can basically use it anywhere. There are two 3.5mm pins for audio in and audio out and a volume control. Very simple and easy to use.
Cosmetically, both units look really good. Minor scuff marks from use but nothing major. Both the headphone and amp will be packed in its folder bag and boxed up for shipment.
