It pairs with them perfectly and gives them their own independent power supply, so they don’t drain the battery of the phone or other device they are plugged into, and it gives them up to 5 hours of extra listening. FiiO also names it as a power source for the QX11’s Desktop Mode. It weighs about 30.8g and comes in a choice of colours.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/FIIOESTICK_790x656_8b06b0a8-4a1a-4bb3-a42a-f0597d20842f.jpg?v=1767217501\" alt=\"FiiO ESTICK alongside a FiiO KA17 dongle DAC\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003ePure power for a purer sound\u003c\/h3\u003e\n\u003cp\u003eThe output circuit uses AVX low-ESR tantalum capacitors for a stable, pure supply with less power ripple, which FiiO says leads to a purer, more detailed sound.
