THE BTR3

The BTR3 is a compact device that weighs just 26g and measures 58mm in length, 25mm in width and 14mm in thickness. In terms of quality the aluminium enclosure which is covered at the top with 2.5D glass may not look special but it's very durable (at the top we see the RGB status LED and the NFC area).

Since we do have a few Bluetooth transmitters/receivers by HAVIT in the lab (HV-BT018) we decided to compare sizes.

On the right side of the BTR3 we find the on/off/reset/switch input button, microphone, reconnect/play/pairing/pause/answer/end calls button and the volume up/previous track and volume down/next track buttons (yes, the tracks feature is inverted compared to what we usually see).

Both the 3.5mm output and the USB type-C port are located at the base of the device.

A shirt clip with the FiiO logo is located at the rear.

For the most part of our tests we used the BTR3 with the M6/M7 music players (again by FiiO) and the Periodic Audio B and DUNU Falcon-C IEMs.
