14. About the Bluetooth transmission distance of FiiO Bluetooth amps(BTR3/BTR1K/BTR1)

A: For the three Bluetooth amps BTR1, BTR1K, BTR3, we have tested their Bluetooth distance separately. Click on the video(or this link) to watch it directly.

The test conditions for the three Bluetooth amps are: 1 Bluetooth paired iPhone 6 (AAC codec); 2 Bluetooth amp is clamped in the right of the front trousers pocket.

Scene description: From the source device to the glass door that is facing, the distance is about 25 meters; at the end of the corridor, it is about 34 meters.

BTR1: In the video, the tester walked back to the source device, and when the glass door passed, the sound began to appear intermittent, and the intermittent condition continued to the end of the corridor. The tester retreats to the approximate glass door position and the sound output is stable and uninterrupted.

Test results: BTR1 in the case of people facing the audio source device, the Bluetooth transmission distance is greater than 20 meters.

BTR1K & BTR3: In the video, the tester is facing away from the source device, and when he walks to the end of the corridor, the sound begins to be intermittent. Later, the tester panned in the break position or stepped back a little, and the sound output was stable and uninterrupted.

Test results: BTR1K and BTR3 Bluetooth transmission distance is greater than 30 meters when the people is facing the audio source device.

Note: Due to different usage scenarios, some usage scenarios may have interference, or different factors such as Bluetooth code selection, there may be some differences in the final test results.
