Fiio RC-BT CSR9645 AptX Bluetooth MMCX HiFi Earphone Cable with Wire Control & Mic


RC-BT Bluetooth Cable

Transform your wired headphones into wireless

Powerful Bluetooth core has the last word on you music

Listen to your lossless music the way it was meant to be heard, but without the mess of wires, anytime anywhere. The RC-BT utilizes the Qualcomm CSR8645 Bluetooth 4.1 chip, which supports the SBC, AAC and aptX audio formats to ensure you get the best out of your music.

Three-button multi-function in-line control center

The in-line control box located on the RC-BT not only allows you to adjust your high quality music playback, but also allows you to stay constantly connected with its high-definition microphone. Make voice calls over Bluetooth with quality on par with the best smartphones.

To enjoy is to be at ease

The RC-BT consumes extremely little power, giving battery life up to 10 hours-enough for a week of listening, 1.5 hours of music per day. And if you do run out of the power, get back up quickly with only 2 hours of charging time. (Quoted times are based on test results under typical conditions. Actual battery life varies depending on playback volume and usage scenarios.)

Get far away from the mess of wires

Enjoy high quality Bluetooth music and calls up to 20 meters away from your source.(Please ensure there are no obstructions between the RC-BT and the Bluetooth device for optimal results.)

Bring your own earphones

While the RC-BT is especially designed to work with the Fiio FH1, F9, F9 Pro and FH5, its standard MMCX connector means you can transform many earphones out on the market into a wireless set with the RC-BT. (The RC-BT is designed for over-the-ear wearing headphones, so it is not suitable for the F5.)

The RC-BT's solitary light indicator tells all you need to know at a glance.

Working: Blue light flashes

Pairing: Red light and blue light flashes alternately
